    Methanolic extract of Morinda citrifolia unripe fruit (MMC) was tested against heroin addiction using a mouse modified runway model of drug‑seeking. Habituation sessions were carried out for 10 min/d for 3 days. On day 0, the total run time of each mouse was noted (the start box to goal box) during the preconditioning test. This was followed by the conditioning session (30 min), in which the animals were conditioned with escalating doses of heroin hydrochloride (5, 10, 20, 40 and 40 mg/kg) for 5 days upon entry into the goal box. On day 6, the run time of each mouse, from start to goal box, was recorded during the post conditioning test. Extinction trials were performed for the next 5 days, in which no drug/saline was injected upon goal box entry. On day 13, a priming dose of heroin (8 mg/kg) was given to reinstate drug seeking in the mice. MMC given as oral doses (1, 3 and 5 g/kg) dose‑dependently prolonged the run time to reach the goal box, indicating MMC attenuated heroin reinforcement. Moreover, MMC (5 g/kg) was found to reverse the heroin‑seeking on extinction trial 1 and 2. MMC was also found to reverse heroin‑induced reinstatement in mice. This study demonstrates that MMC attenuated heroin seeking at different phases of drug self‑administration in a mouse modified runway model.

    The Noni fruit, or scientifically known as Morinda citrifolia can be found in various parts of the world, especially in the pacific region. It is a small evergreen bushy-like tree originated from the Rubiaceae family. The plant has been used by polynesians as a medicinal herb for more than 2000 years. A substantial amount of phytochemicals can be found in the roots of this plant. Among all, damnacanthal has been found to be the most interesting, versatile and potent compound. Damnacanthal or chemically known as,3- hydroxy-1-methoxyanthraquinone-2-caboxaldehyde (C16H10O5), appears as pale yellow crystals with a melting point of 210-211 °C. This compound is of particular interest due to its striking pharmacological properties. Damnacanthal was shown to inhibit the oncogene Ras, p56lck tyrosine kinase, NF-KB pathway and induce apoptosis in vitro. This review aims to discuss the biological properties of damnacanthal, specifically on its anti-cancer activity that has been reported.

    Cancer is one of the most common causes of death in the developed world, with one-third of people diagnosed with
    cancer during their lifetime. Oral cancer commonly occurs involving the buccal mucosa (cheeks), tongue, floor of the
    mouth and lip. It is one of the most devastating and disfiguring of malignancies. Morinda citrifolia L., commonly known
    as ‘noni’, belongs to the Rubiaceae family. It is native to the Pacific islands, Hawaii, Caribbean, Asia and Australia.
    The plant displays broad curative effects in pharmacological studies. Damnacanthal (DAM) and Nordamnacanthal
    (NDAM), anthraquinone compounds isolated from the roots of Morinda citrifolia L., has been used for the treatment
    of several chronic diseases including cancer. The objectives of this study were to evaluate cytotoxicity, morphological
    changes, cell death mode (apoptosis/necrosis), and cell migration induced by DAM and NDAM on the most common
    type of oral cancer, oral squamous cell carcinoma (OSCC)cells. Anti-proliferative effects of these compounds against
    OSCC cell lines were determined by MTT assay. The mode of cell death was analysed by phase contrast and fluorescent
    microscopy as well as flow cytometry. In addition, cell migration was assessed. The results showed that DAM and
    NDAM exerted cytotoxicity against OSCC cells with IC50 values of 1.9 to >30 μg/ml after 72 h treatment. Maximum
    growth inhibition among the tested cell lines for both compounds was observed in H400 cells, and thus it was selected
    for further study. The study demonstrated inhibition of H400 OSCC cell proliferation, marked apoptotic morphological
    changes, induction of early apoptosis, and inhibition of cell migration by DAM and NDAM. Therefore, this information
    suggests that these compounds from noni have potential for used as anti tumor agents for oral cancer therapy.

    PMID: 22449521 DOI: 10.1016/S1995-7645(12)60042-X
    OBJECTIVE: Toinvestigate the anti-angiogenic activity and antioxidant properties of Myristica fragrans (M. fragrans) (nutmeg) and Morinda citrifolia (M. citrifolia)(mengkudu) oils.

    METHODS: The nutmeg and megkudu essential oils were obtained by steam distillation. The antioxidant activities of both essential oils were determined by beta-carotene/linoleic acid bleaching assay and reducing power while the anti-angiogenic activity was investigated using rat aortic ring assay using various concentrations.

    RESULTS: The results showed that nutmeg oil has higher antioxidant activity than mengkudu oil. The nutmeg oil effectively inhibited the oxidation of linoleic acid with (88.68±0.1)% while the inhibition percentage of oxidation of linoleic acid of the mengkudu oil is (69.44±0.4)%. The nutmeg oil and mengkudu oil showed reducing power with an EC(50) value of 181.4 μg/mL and 3 043.0 μg/mL, respectively. The antiangiogenic activity of nutmeg oil showed significant antiangiogenic activity with IC(50) of 77.64 μg/mL comparing to mengkudu oil which exhibits IC(50) of 109.30 μg/mL.

    CONCLUSIONS: Bioactive compound(s) will be isolated from the nutmeg essential oil to be developed as antiangiogenic drugs.

    PMID: 29374471 DOI: 10.1186/s12906-018-2102-3
    BACKGROUND: Morinda citrifolia L. that was reported with immunomodulating and cytotoxic effects has been traditionally used to treat multiple illnesses including cancer. An anthraquinone derived from fruits of Morinda citrifolia L., nordamnacanthal, is a promising agent possessing several in vitro biological activities. However, the in vivo anti-tumor effects and the safety profile of nordamnacanthal are yet to be evaluated.

    METHODS: In vitro cytotoxicity of nordamnacanthal was tested using MTT, cell cycle and Annexin V/PI assays on human MCF-7 and MDA-MB231 breast cancer cells. Mice were orally fed with nordamnacanthal daily for 28 days for oral subchronic toxicity study. Then, the in vivo anti-tumor effect was evaluated on 4T1 murine cancer cells-challenged mice. Changes of tumor size and immune parameters were evaluated on the untreated and nordamnacanthal treated mice.

    RESULTS: Nordamnacanthal was found to possess cytotoxic effects on MDA-MB231, MCF-7 and 4T1 cells in vitro. Moreover, based on the cell cycle and Annexin V results, nordamnacanthal managed to induce cell death in both MDA-MB231 and MCF-7 cells. Additionally, no mortality, signs of toxicity and changes of serum liver profile were observed in nordamnacanthal treated mice in the subchronic toxicity study. Furthermore, 50 mg/kg body weight of nordamncanthal successfully delayed the progression of 4T1 tumors in Balb/C mice after 28 days of treatment. Treatment with nordamnacanthal was also able to increase tumor immunity as evidenced by the immunophenotyping of the spleen and YAC-1 cytotoxicity assays.

    CONCLUSION: Nordamnacanthal managed to inhibit the growth and induce cell death in MDA-MB231 and MCF-7 cell lines in vitro and cease the tumor progression of 4T1 cells in vivo. Overall, nordamnacanthal holds interesting anti-cancer properties that can be further explored.

  7. Methanolic extract of Morinda citrifolia Linn. unripe fruit attenuates methamphetamine-induced conditioned place preferences in mice
    Pandy V, Wai YC, Amira Roslan NF, Sajat A, Abdulla Jallb AH, Vijeepallam K
    Biomed Pharmacother, 2018 Nov;107:368-373.
    PMID: 30099340 DOI: 10.1016/j.biopha.2018.08.008
    The first objective of the present study was to determine the appropriate dose of methamphetamine (Meth) to induce a successful conditioned place preference (CPP) in mice. The next objective was to examine the effect of a methanolic extract of M. citrifolia unripe fruit (MMC) against Meth-induced CPP in mice. In answering to the first objective, following the preconditioning test, an intraperitoneal injection of a fixed dose of Meth (0.5 or 1 or 2 mg/kg, i.p.) or saline (10 ml/kg, i.p.) was given on alternate days during the 10 days conditioning period followed by a postconditioning test conducted in Meth-free state. The first experiment revealed that 0.5 mg/kg of Meth could be an appropriate fixed low dose to induce CPP in mice. Meanwhile, in other experiments, the effect of MMC and bupropion (BUPR) against the expression, extinction, and reinstatement of Meth (0.5 mg/kg)-induced CPP in mice, respectively, was investigated. In a separate set of studies on each phase, an oral administration of MMC (1, 3 and 5 g/kg, p.o.) or BUPR (20 mg/kg, p.o.) was given 60 min prior to CPP postconditioning testing or extinction testing or reinstatement testing in mice. Extinction trials were conducted in Meth-free state to weaken CPP over the next 5 days. Reinstatement test was conducted by a single low dose priming injection of Meth (0.1 mg/kg, i.p.). The present study, however, failed to establish a successful extinction and reinstatement of Meth-CPP in mice. Further studies using other doses of Meth are warranted for a successful establishment of all phases of Meth CPP in mice. This study also demonstrates that MMC (3 and 5 g/kg, p.o.) and BUPR (20 mg/kg, p.o.) could attenuate the expression of Meth-induced CPP in mice.

  8. Anxiolytic- and antidepressant-like activities of a methanolic extract of Morinda citrifolia Linn. (noni) fruit in mice: Involvement of benzodiazepine-GABAAergic, serotonergic and adrenergic systems
    Narasingam M, Vijeepallam K, Mohamed Z, Pandy V
    Biomed Pharmacother, 2017 Dec;96:944-952.
    PMID: 29217165 DOI: 10.1016/j.biopha.2017.11.148
    This study presents anxiolytic- and antidepressant-like effects of a methanolic extract of Morinda citrifolia Linn. (noni) fruit (MMC) in well-established mouse models of anxiety and depression. The administration of MMC (1 g/kg, p.o.) and diazepam (1 mg/kg, i.p.) significantly attenuated anxiety-like behaviour in mice by increasing the percentage of time spent and number of entries in the open arms in the elevated plus maze (EPM), and significantly enhanced the exploration in the light box in the light/dark test (LDT). The pre-treatment with flumazenil (6 mg/kg, i.p.) or bicuculline (3 mg/kg, i.p.) or WAY 100635 (1 mg/kg, i.p.) antagonized the anxiolytic-like effect elicited by MMC (1 g/kg, p.o.). These results suggest the possible involvement of benzodiazepine-GABAAergic and serotonergic mechanisms in the anxiolytic-like effect of noni fruit. Meanwhile, in the antidepressant study, the administration of MMC (0.5 and 0.75 g/kg, p.o.) and desipramine (30 mg/kg, i.p.) significantly reduced the duration of immobility in the tail suspension test (TST). Furthermore, pre-treatment of mice with 4-chloro-DL-phenylalanine methyl ester hydrochloride (PCPA; 100 mg/kg, i.p., an inhibitor of serotonin synthesis) for four consecutive days or a single dose of WAY 100635 (1 mg/kg, i.p., 5HT1A receptor antagonist) or α-methyl-DL-tyrosine (AMPT; 100 mg/kg, i.p., an inhibitor of noradrenaline synthesis) significantly reversed the anti-immobility effect of MMC (0.5 g/kg, p.o.) in TST by indicating the specific involvement of the serotonergic and noradrenergic systems in the antidepressant-like effect of noni fruit. Taken together, these findings suggest that MMC has both anxiolytic- and antidepressant-like activities to be resorted as a valuable alternative therapy for comorbid anxiety and depressive conditions.

    PMID: 34436826 DOI: 10.1002/tox.23353
    Morinda elliptica L. (Rubiaceae) is a phytomedicinal herb, used to treat gastrointestinal complications in Peninsular Malaysia. The study evaluates the in vivo hepatoprotective activity of ethanolic extract of M. elliptica stem in thioacetamide (TAA) induced liver fibrosis in male Sprague Drawly rats. Thirty adult rats were divided into five groups of six rats each. Rats of the normal control group received intraperitoneal injections (i. p.) of vehicle 10% Tween-20, 5 ml/kg, and hepatotoxic group 200 mg/kg TAA three times per week respectively. Three supplementary groups were treated with TAA plus daily oral silymarin (50 mg/kg) or M. elliptica (250 or 500 mg/kg). After 8 weeks of treatment, all rats were sacrificed. Liver fibrosis was assessed by gross macroscopic and microscopic tissue analysis, histopathological, and biochemical analysis. The livers of the TAA treated group showed uniform coarse granules, hepatocytic necrosis with lymphocytes infiltration. Contrary, the livers of M. elliptica treated groups (250 and 500 mg/kg) were much smoother and the cell damage was much lesser. The livers of M. elliptica treated groups rats showed elevated activity of SOD and CAT with a significant decrease in MDA level at p

  10. Fulltext Noni (Morinda citrifolia L.) fruit extract attenuates the rewarding effect of heroin in conditioned place preference but not withdrawal in rodents
    Narasingam M, Pandy V, Mohamed Z
    Exp Anim, 2016 May 20;65(2):157-64.
    PMID: 26744024 DOI: 10.1538/expanim.15-0088
    The present study was designed to investigate the effect of a methanolic extract of Morinda citrifolia Linn. fruit (MMC) on the rewarding effect of heroin in the rat conditioned place preference (CPP) paradigm and naloxone-precipitated withdrawal in mice. In the first experiment, following a baseline preference test (preconditioning score), the rats were subjected to conditioning trials with five counterbalanced escalating doses of heroin versus saline followed by a preference test conducted under drug-free conditions (post-conditioning score) using the CPP test. Meanwhile, in the second experiment, withdrawal jumping was precipitated by naloxone administration after heroin dependence was induced by escalating doses for 6 days (3×/ day). The CPP test results revealed that acute administration of MMC (1, 3, and 5 g/kg body weight (bw), p.o.), 1 h prior to the CPP test on the 12th day significantly reversed the heroin-seeking behavior in a dose-dependent manner, which was similar to the results observed with a reference drug, methadone (3 mg/kg bw, p.o.). On the other hand, MMC (0.5, 1, and 3 g/kg bw, p.o.) did not attenuate the heroin withdrawal jumps precipitated by naloxone. These findings suggest that the mechanism by which MMC inhibits the rewarding effect of heroin is distinct from naloxone-precipitated heroin withdrawal.

  11. Fulltext Antipsychotic-like activity of scopoletin and rutin against the positive symptoms of schizophrenia in mouse models
    Pandy V, Vijeepallam K
    Exp Anim, 2017 Oct 30;66(4):417-423.
    PMID: 28701621 DOI: 10.1538/expanim.17-0050
    In an earlier report, we demonstrated an antipsychotic-like activity of a methanolic extract of Morinda citrifolia Linn fruit in mouse models and postulated the contribution of its bioactive principles, scopoletin and rutin. Moreover, the antidopaminergic activities of scopoletin and rutin were reported in isolated vas deferens preparations. In the present study, scopoletin and rutin were assessed for antipsychotic-like activity using apomorphine-induced climbing behavior and methamphetamine-induced stereotypy in mice. The results of this study revealed that scopoletin and rutin (0.05, 0.1, 0.5, and 1 mg/kg, p.o.) had a "U-shaped" dose-dependent effect on climbing and stereotyped behaviors induced by apomorphine and methamphetamine, respectively, in mice. A significant reduction in climbing and stereotyped behaviors caused by scopoletin and rutin was observed only at a dose 0.1 mg/kg. This study suggests that scopoletin and rutin can alleviate positive symptoms of schizophrenia only at a specific dose. Further studies evaluating the effects of scopoletin and rutin on animal models for negative symptoms of schizophrenia are required for a novel drug discovery in the treatment of neuropsychiatric diseases.

  12. Fulltext The ethyl acetate fraction of a methanolic extract of unripe noni (Morinda citrifolia Linn.) fruit exhibits a biphasic effect on the dopaminergic system in mice
    Pandy V, Narasingam M, Vijeepallam K, Mohan S, Mani V, Mohamed Z
    Exp Anim, 2017 Aug 05;66(3):283-291.
    PMID: 28450692 DOI: 10.1538/expanim.16-0105
    In earlier ex vivo studies, we reported the biphasic effect of a methanolic extract of unripe Morinda citrifolia fruit (MMC) on dopamine-induced contractility in isolated rat vas deferens preparations. The present in vivo study was designed and undertaken to further explore our earlier ex vivo findings. This study examined the effect of the ethyl acetate fraction of a methanolic extract of unripe Morinda citrifolia Linn. fruit (EA-MMC; 5-100 mg/kg, p.o.) on the dopaminergic system using mouse models of apomorphine-induced climbing time and climbing behavior, methamphetamine-induced stereotypy (sniffing, biting, gnawing, and licking) and haloperidol-induced catalepsy using the bar test. Acute treatment with EA-MMC at a low dose (25 mg/kg, p.o.) significantly attenuated the apomorphine-induced climbing time and climbing behavior in mice. Similarly, EA-MMC (5 and 10 mg/kg, p.o.) significantly inhibited methamphetamine-induced stereotyped behavior in mice. These results demonstrated that the antidopaminergic effect of EA-MMC was observed at relatively lower doses (<25 mg/kg, p.o.). On the other hand, EA-MMC showed dopaminergic agonistic activity at a high dose (3,000 mg/kg, p.o.), which was evident from alleviation of haloperidol (a dopamine D2 blocker)-induced catalepsy in mice. Therefore, it is concluded that EA-MMC might possess a biphasic effect on the dopaminergic system, i.e., an antagonistic effect at lower doses (<25 mg/kg, p.o.) and an agonistic effect at higher doses (>1,000 mg/kg, p.o.). However, further receptor-ligand binding assays are necessary to confirm the biphasic effects of M. citrifolia fruit on the dopaminergic system.

  13. Noni (Morinda citrifolia Linn.) fruit juice attenuates the rewarding effect of ethanol in conditioned place preference in mice
    Pandy V, Khan Y
    Exp Anim, 2016 Nov 1;65(4):437-445.
    PMID: 27333840
    Morinda citrifolia L. commonly known as noni or Indian mulberry belongs to the family Rubiaceae. Noni fruit juice has recently become a very popular remedy for the treatment of several diseases, including psychiatric disorders. This study aimed to investigate the anticraving effect of Tahitian Noni® Juice (TNJ) against ethanol seeking behavior in ICR male mice using the conditioned place preference (CPP) test. The CPP procedure consisted of four phases: preconditioning, conditioning, extinction, and reinstatement. During conditioning, intraperitoneal (i.p.) injections of ethanol (2 g/kg body weight (bw)) and normal saline (10 ml/kg bw) were given on alternate days for 12 days. Then, the animals were subjected to extinction trials for the next 12 days to weaken CPP. Finally, CPP was reinstated in the extinguished animals by a single low-dose priming injection of ethanol (0.4 g/kg bw, i.p.). The effect of TNJ (as a source of drinking water) on different phases of ethanol CPP in mice was studied. TNJ-treated mice showed a significant reduction in ethanol seeking behavior in the CPP test. The reference drug, acamprosate (ACAM) also showed a similar effect in the CPP test. The outcome of this study suggests that TNJ is effective in attenuating ethanol craving in mice and could be utilized for the treatment of alcohol dependence. Further clinical studies in this direction are warranted to support the present preclinical findings.

    Food Funct, 2021 Mar 18.
    PMID: 33734250 DOI: 10.1039/d0fo03402a
    Morinda citrifolia L. is a plant of the family Rubiaceae and is known as Indian mulberry or Noni in India. It is a perennial herb native to Southeast Asia and has been used over the years as a food supplement and medicinal plant. Noni fruits are reported to possess anticancer, fungicidal, antiviral and antiarthritic effects. The objective of our study is the screening of the immunomodulatory activity of the total extract, fractions, and isolated compounds of Noni fruits to identify their bioactive compounds. To achieve our goal, an ethanol extract (EE) was prepared from Noni fruits. Fractionation and purification of the EE were accomplished. The cell-mediated immune (CMI) response in prednisolone-induced immunosuppression rats was evaluated. The toxicity of the EE, fractions and isolated compounds on the differentiated THP-1 macrophage was assessed using the MTT viability assay. Moreover, the inflammation-related immune responses in lipopolysaccharide (LPS)-induced THP-1 macrophage activation were evaluated. Fractionation of the EE gave three fractions, dichloromethane (DCMF), water (WF) and methanol (MF). Purification of DCMF yielded stigmast-7-ene-3-ol (M1), 28-hydroxy-3β-acetoxy-9-dehydrogramisterol (M2), 3β-acetoxy-taraxast-20(30)-ene-21-ol (M3), 22-dehydroclerosterol (M4) and 22-dehydroclerosterol-3-O-β-d-glucopyranoside (M5), while purification of MF yielded quercetin (M6), hesperidin (M7), naringin (M9) and gallic acid (M8). The results revealed that DCMF elicited an increase in paw edema to the extent of 35.8%. All the tested samples had no cytotoxic effect on THP-1 macrophages. Co-treatment of the LPS-induced macrophages with DCMF, M2, M3, and M6 decreased the production of TNF-α, IL-1β, and IL-6/IL-10. The expression of iNOS, COX-2, and NF-κB decreased to 0.14 ± 0.02, 0.15 ± 0.02, and 0.17 ± 0.03, respectively, after co-treatment with LPS and DCMF. M2 attenuated the expression of iNOS and NF-κB to 0.18 ± 0.03 and 0.17 ± 0.03, respectively. Additionally, M3 attenuated the expression of iNOS to 0.18 ± 0.03, and after co-treatment with M6 and LPS, the expression of COX-2 and NF-κB was down-regulated to 0.2 ± 0.03. Our study proves the immunomodulatory effect of Noni fruits and specifies for the first time the compounds responsible for their activity.

    PMID: 27374554 DOI: 10.1016/j.foodchem.2016.05.179
    Morinda citrifolia fruit, (noni), enhanced performances in athletes and post-menopausal women in clinical studies. This report shows the edible noni leaves water extract enhances performance in a weight-loaded swimming animal model better than the fruit or standardized green tea extract. The 4weeks study showed the extract (containing scopoletin and epicatechin) progressively prolonged the time to exhaustion by threefold longer than the control, fruit or tea extract. The extract improved (i) the mammalian antioxidant responses (MDA, GSH and SOD2 levels), (ii) tissue nutrient (glucose) and metabolite (lactate) management, (iii) stress hormone (cortisol) regulation; (iv) neurotransmitter (dopamine, noradrenaline, serotonin) expressions, transporter or receptor levels, (v) anti-inflammatory (IL4 & IL10) responses; (v) skeletal muscle angiogenesis (VEGFA) and (v) energy and mitochondrial biogenesis (via PGC, UCP3, NRF2, AMPK, MAPK1, and CAMK4). The ergogenic extract helped delay fatigue by enhancing energy production, regulation and efficiency, which suggests benefits for physical activities and disease recovery.

    PMID: 27729866
    Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on compulsive ethanol-seeking behavior using the mouse conditioned place preference (CPP) test. CPP was established by injections of ethanol (2 g/kg, i.p.) in a 12-day conditioning schedule in mice. The effect of MMC and the reference drug, acamprosate (ACAM), on the reinforcing properties of ethanol in mice was studied by the oral administration of MMC (1, 3, and 5 g/kg) and ACAM (300 mg/kg) 60 min prior to the final CPP test postconditioning. Furthermore, CPPs weakened with repeated testing in the absence of ethanol over the next 12 days (extinction), during which the treatment groups received MMC (1, 3, and 5 g/kg, p.o.) or ACAM (300 mg/kg, p.o.). Finally, a priming injection of a low dose of ethanol (0.4 g/kg, i.p.) in the home cage (Reinstatement) was sufficient to reinstate CPPs, an effect that was challenged by the administration of MMC or ACAM. MMC (3 and 5 g/kg, p.o.) and ACAM (300 mg/kg, p.o.) significantly reversed the establishment of ethanol-induced CPPs and effectively facilitated the extinction of ethanol CPP. In light of these findings, it has been suggested that M. citrifolia unripe fruit could be utilized for novel drug development to combat alcohol dependence.

    Cancer is a major cause of morbidity and mortality worldwide and therefore there has been interest in discovering the phytoconstituents of medicinal plants exhibiting anticancer activities. Morinda citrifolia L., commonly known as Noni, has shown anticancer properties in in vitro, in vivo, and in clinical studies. A systematic review was conducted to collate scientific evidence on the anticancer properties of M. citrifolia using pre-determined keywords on 5 electronic databases: MEDLINE, CENTRAL, LILACS, Web of Science, and EBSCOHost. A total of 51 clinical and preclinical studies comprising 41 efficacy and 10 safety studies were included in this review. Our findings showed that M. citrifolia demonstrated various anticancer properties in different cancer models, via multiple mechanisms including antitumor, antiproliferative, pro-apoptotic, antiangiogenesis, antimigratory, anti-inflammatory, and immunomodulatory activities. M. citrifolia is deemed to be a potentially valuable medicinal plant in the treatment of cancer through its many intrinsic pathways. More well-designed and reported preclinical efficacy and safety studies are needed to allow for better translation into future clinical studies which could further substantiate the role of M. citriflolia in cancer treatment.

    The antibacterial activity of solvent-extracted oil of noni (Morinda citrifolia L.), spinach (Spinacia oleracea L.), lady’s finger (Abelmoschus esculentus (L.) Moench), bitter gourd (Momordica charantia Linn.), and mustard (Brassica nigra L.) seed oils, and coconut (Cocos nucifera L.) oil, palm (Elaeis guineensis L.) mesocarp in hydrolyzed and unhydrolyzed form were determined in order to explore their potential usage as antibacterial agent. The hydrolysis process that was catalyzed by immobilized lipase of Rhizomucor miehei (RMIM) showed highest hydrolytic activity with 1.0 ml of added water volume except bitter gourd seed oil and palm mesocarp oil which has maximum hydrolytic activity with added water volume of 5 ml and 2.5 ml respectively. Before hydrolysis, all oil samples did not show inhibition ring zones (IRZ) on any of the tested bacteria strains (Salmonella typhimurium, Listeria monocytogenes and Escherichia coli O157:H7). Hydrolyzed lady’s finger and bitter gourd seed oil showed IRZ on all tested bacteria strains; hydrolyzed mustard seed oil on S. typhimurium and L. monocytogenes; hydrolyzed spinach seed oil and coconut oil on L. monocytogenes; hydrolyzed noni seed oil and palm mesocarp oil did not exhibit IRZ on any of the tested bacteria strains. Most of the hydrolyzed oil exhibit an inhibition activity that was different from their respective dominant fatty acids except noni seed oil and palm mesocarp oil.

    A study was carried out to observe the fermentation process for noni (Morinda citrifolia L.) extract by Saccharomyces cerevisiae. The experiment was based on a central composite rotatable design (CCRD) employing 5 center points with augmented axial and factorial points resulting in 30 runs. The M. citrifolia extract was fermented with different combination of substrate concentration (40, 50, 60, 70 and 80%) (w/v), inoculum size (0, 1.5, 3, 4.5 and 6%) (v/v), temperature (30, 33.5, 37, 40.5 and 44oC) and fermentation time (0, 1.5, 3, 4.5 and 6 days). Five physico-chemical characteristics which include pH, titratable acidity, turbidity, total soluble solids and total polyphenol content were measured. Results showed that all the responses could be well represented using statistical models. For pH, only fermentation time was found to be not significant, while for titratable acidity and total polyphenol content, the effects of substrate concentration and fermentation time were significant. The effects of inoculum size and temperature level were found to be significant for turbidity. For total soluble solids, only the effect of substrate concentration and inoculum size were found to be significant.
