New Guinea has the world's richest island flora

Cámara-Leret R, Frodin DG, Adema F, Anderson C, Appelhans MS, Argent G, et al.

Nature, 2020 08;584(7822):579-583.
PMID: 32760001 DOI: 10.1038/s41586-020-2549-5

New Guinea is the world's largest tropical island and has fascinated naturalists for centuries1,2. Home to some of the best-preserved ecosystems on the planet3 and to intact ecological gradients-from mangroves to tropical alpine grasslands-that are unmatched in the Asia-Pacific region4,5, it is a globally recognized centre of biological and cultural diversity6,7. So far, however, there has been no attempt to critically catalogue the entire vascular plant diversity of New Guinea. Here we present the first, to our knowledge, expert-verified checklist of the vascular plants of mainland New Guinea and surrounding islands. Our publicly available checklist includes 13,634 species (68% endemic), 1,742 genera and 264 families-suggesting that New Guinea is the most floristically diverse island in the world. Expert knowledge is essential for building checklists in the digital era: reliance on online taxonomic resources alone would have inflated species counts by 22%. Species discovery shows no sign of levelling off, and we discuss steps to accelerate botanical research in the 'Last Unknown'8.

PMID: 34066963 DOI: 10.3390/molecules26092741

Leukemia is a leukocyte cancer that is characterized by anarchic growth of immature immune cells in the bone marrow, blood and spleen. There are many forms of leukemia, and the best course of therapy and the chance of a patient's survival depend on the type of leukemic disease. Different forms of drugs have been used to treat leukemia. Due to the adverse effects associated with such therapies and drug resistance, the search for safer and more effective drugs remains one of the most challenging areas of research. Thus, new therapeutic approaches are important to improving outcomes. Almost half of the drugs utilized nowadays in treating cancer are from natural products and their derivatives. Medicinal plants have proven to be an effective natural source of anti-leukemic drugs. The cytotoxicity and the mechanisms underlying the toxicity of these plants to leukemic cells and their isolated compounds were investigated. Effort has been made throughout this comprehensive review to highlight the recent developments and milestones achieved in leukemia therapies using plant-derived compounds and the crude extracts from various medicinal plants. Furthermore, the mechanisms of action of these plants are discussed.

PMID: 17568375 MyJurnal

Seven Malaysian medicinal plants were screened for their antiplasmodial activities in vitro. These plants were selected based on their traditional claims for treatment or to relieve fever. The plant extracts were obtained from Forest Research Institute Malaysia (FRIM). The antiplasmodial activities were carried out using the pLDH assay to Plasmodium falciparum D10 strain (sensitive strain) while the cytotoxic activities were carried out towards Madin- Darby bovine kidney (MDBK) cells using MTT assay. The concentration of extracts used for both screening assays were from the highest concentration 64 microg/ml, two fold dilution to the lowest concentration 0.03 microg/ml. Goniothalamus macrophyllus (stem extract) showed more than 60% growth inhibition while Goniothalamus scortechinii root and stem extract showed a 90% and more than 80% growth inhibition at the last concentration tested, 0.03 microg/ml. The G. scortechini (leaves extract) showed an IC50 (50% growth inhibition) at 8.53 microg/ml, Ardisia crispa (leaves extract) demonstrated an IC50 at 5.90 +/- 0.14 microg/ml while Croton argyratus (leaves extract) showed a percentage inhibition of more than 60% at the tested concentration. Blumea balsamifera root and stem showed an IC50 at 26.25 +/- 2.47 microg/ml and 7.75 +/- 0.35 microg/ ml respectively. Agathis borneensis (leaves extract) demonstrated a 50% growth inhibition at 11.00 +/- 1.41 microg/ml. The study gives preliminary scientific evidence of these plant extracts in line with their traditional claims.

Letchumanan D, Sok SPM, Ibrahim S, Nagoor NH, Arshad NM

Biomolecules, 2021 04 12;11(4).
PMID: 33921379 DOI: 10.3390/biom11040564

Plants are rich in phytoconstituent biomolecules that served as a good source of medicine. More recently, they have been employed in synthesizing metal/metal oxide nanoparticles (NPs) due to their capping and reducing properties. This green synthesis approach is environmentally friendly and allows the production of the desired NPs in different sizes and shapes by manipulating parameters during the synthesis process. The most commonly used metals and oxides are gold (Au), silver (Ag), and copper (Cu). Among these, Cu is a relatively low-cost metal that is more cost-effective than Au and Ag. In this review, we present an overview and current update of plant-mediated Cu/copper oxide (CuO) NPs, including their synthesis, medicinal applications, and mechanisms. Furthermore, the toxic effects of these NPs and their efficacy compared to commercial NPs are reviewed. This review provides an insight into the potential of developing plant-based Cu/CuO NPs as a therapeutic agent for various diseases in the future.

Mustapa MAC, Batcha MFN, Amin L, Arham AF, Mahadi Z, Yusoff NAM, et al.

J Sci Food Agric, 2021 Oct;101(13):5457-5468.
PMID: 33709409 DOI: 10.1002/jsfa.11194

BACKGROUND: Genetically modified (GM) crops have become a controversial global issue since their commercialization in 1996. However, despite technological advancements, only a few studies have investigated farmers' attitudes towards GM crops in Malaysia. Therefore, this study aims to analyse such attitudes and their determining factors. A validated questionnaire was distributed to farmers in the Cameron Highlands, Pahang (n = 176). SPSS software was used to analyse the descriptive statistics of the farmers' attitudes to GM crops, while SmartPLS software was used to determine the predictors.
RESULTS: Descriptive analysis shows that the farmers claimed to have a high level of self-efficacy, and perceived GM crops as possessing high benefits which translate into a highly positive attitude towards GM crops. However, at the same time, they rated GM crops as involving moderate risks and would incur moderate costs to farm, as well as acknowledging a low level of support from the government. The structural equation model (SEM) analysis demonstrates that five factors have been identified as direct predictors of attitude to GM crops: government support (ß = 0.364, P

Complete genome sequence of plant growth-promoting and heavy metal-tolerant Enterobacter tabaci 4M9 (CCB-MBL 5004)

Abdullahi S, Haris H, Zarkasi KZ, Amir HG

J Basic Microbiol, 2021 Apr;61(4):293-304.
PMID: 33491813 DOI: 10.1002/jobm.202000695

Enterobacter tabaci 4M9 (CCB-MBL 5004) was reported to have plant growth-promoting and heavy metal tolerance traits. It was able to tolerate more than 300 mg/L Cd, 600 mg/L As, and 500 mg/L Pb and still maintained the ability to produce plant growth-promoting substances under metal stress conditions. To explore the genetic basis of these beneficial traits, the complete genome sequencing of 4M9 was carried out using Pacific Bioscience (PacBio) sequencing technology. The complete genome consisted of one chromosome of 4,654,430 bp with a GC content of 54.6% and one plasmid of 51,135 bp with a GC content of 49.4%. Genome annotation revealed several genes involved in plant growth-promoting traits, including the production of siderophore, indole acetic acid, and 1-aminocyclopropane-1-carboxylate deaminase; solubilization of phosphate and potassium; and nitrogen metabolism. Similarly, genes involved in heavy metals (As, Co, Zn, Cu, Mn, Se, Cd, and Fe) tolerance were detected. These support its potential as a heavy metal-tolerant plant growth-promoting bacterium and a good genetic resource that can be employed to improve phytoremediation efficiency of heavy metal-contaminated soil via biotechnological techniques. This, to the best of our knowledge, is the first report on the complete genome sequence of heavy metal-tolerant plant growth-promoting E. tabaci.

Wong LC, Leh CP, Goh CF

Carbohydr Polym, 2021 Jul 15;264:118036.
PMID: 33910744 DOI: 10.1016/j.carbpol.2021.118036

Hydrogels are an attractive system for a myriad of applications. While most hydrogels are usually formed from synthetic materials, lignocellulosic biomass appears as a sustainable alternative for hydrogel development. The valorization of biomass, especially the non-woody biomass to meet the growing demand of the substitution of synthetics and to leverage its benefits for cellulose hydrogel fabrication is attractive. This review aims to present an overview of advances in hydrogel development from non-woody biomass, especially using native cellulose. The review will cover the overall process from cellulose depolymerization, dissolution to crosslinking reaction and the related mechanisms where known. Hydrogel design is heavily affected by the cellulose solubility, crosslinking method and the related processing conditions apart from biomass type and cellulose purity. Hence, the important parameters for rational designs of hydrogels with desired properties, particularly porosity, transparency and swelling characteristics will be discussed. Current challenges and future perspectives will also be highlighted.

Baraya YS, Wong KK, Yaacob NS

Anticancer Agents Med Chem, 2017;17(6):770-783.
PMID: 27539316 DOI: 10.2174/1871520616666160817111242

Breast cancer has continued to cause high cancer death rates among women worldwide. The use of plants' natural products in breast cancer treatment has received more attention in recent years due to their potentially wider safety margin and the potential to complement conventional chemotherapeutic drugs. Plantbased products have demonstrated anticancer potential through different biological pathways including modulation of the immune system. Immunomodulatory properties of medicinal plants have been shown to mitigate breast cancer cell growth. Different immune cell types participate in this process especially cytotoxic T cells and natural killer cells, and cytokines including chemokines and tumor necrosis factor-α. Medicinal plants such as Glycyrrhiza glabra, Uncaria tomentosa, Camellia sinensis, Panax ginseng, Prunus armenaica (apricot), Allium sativum, Arctium lappa and Curcuma longa were reported to hold strong potential in breast cancer treatment in various parts of the world. Interestingly, research findings have shown that these plants possess bioactive immunomodulators as their main constituents producing the anticancer effects. These immunomodulatory compounds include ajoene, arctigenin, β-carotene, curcumin, epigallocatechin-3-gallate, ginsan, glabridin and quinic acid. In this review, we discussed the ability of these eight immunomodulators in regulating the immune system potentially applicable in breast cancer treatment via anti-inflammatory (curcumin, arctigenin, glabridin and ajoene) and lymphocytes activation (β-carotene, epigallocatechin-3-gallate, quinic acid and ginsan) properties, as well as future research direction in their use for breast cancer treatment.

Bioengineering of the Plant Culture of Capsicum frutescens with Vanillin Synthase Gene for the Production of Vanillin

Chee MJ, Lycett GW, Khoo TJ, Chin CF

Mol Biotechnol, 2017 Jan;59(1):1-8.
PMID: 27826796 DOI: 10.1007/s12033-016-9986-2

Production of vanillin by bioengineering has gained popularity due to consumer demand toward vanillin produced by biological systems. Natural vanillin from vanilla beans is very expensive to produce compared to its synthetic counterpart. Current bioengineering works mainly involve microbial biotechnology. Therefore, alternative means to the current approaches are constantly being explored. This work describes the use of vanillin synthase (VpVAN), to bioconvert ferulic acid to vanillin in a plant system. The VpVAN enzyme had been shown to directly convert ferulic acid and its glucoside into vanillin and its glucoside, respectively. As the ferulic acid precursor and vanillin were found to be the intermediates in the phenylpropanoid biosynthetic pathway of Capsicum species, this work serves as a proof-of-concept for vanillin production using Capsicum frutescens (C. frutescens or hot chili pepper). The cells of C. frutescens were genetically transformed with a codon optimized VpVAN gene via biolistics. Transformed explants were selected and regenerated into callus. Successful integration of the gene cassette into the plant genome was confirmed by polymerase chain reaction. High-performance liquid chromatography was used to quantify the phenolic compounds detected in the callus tissues. The vanillin content of transformed calli was 0.057% compared to 0.0003% in untransformed calli.

Coca leaf and cocaine addiction--some historical notes

Blejer-Prieto H

Can Med Assoc J, 1965 Sep 25;93(13):700-4.
PMID: 5318484

Coca-leaf habituation has affected millions of Andean natives for over 400 years. In the last half-century it has also involved millions more Malayans. Coca leaf, from which cocaine and extracts for some commercial carbonated soft drinks are obtained, remains relatively unknown by the medical and allied professions elsewhere. A review of the original medical, historical and other pertinent literature of the last 350 years illustrates the origins of the use of coca leaf, its spread, the isolation of cocaine and its first uses, as well as some of the euphoric and other effects of both substances.

The influences of thermal processing on phytochemicals and possible routes to the discovery of new phytochemical conjugates

Wong FC, Chai TT, Xiao J

Crit Rev Food Sci Nutr, 2019;59(6):947-952.
PMID: 29787299 DOI: 10.1080/10408398.2018.1479681

In our diets, many of the consumed foods are subjected to various forms of heating and thermal processing. Besides enhancing the taste, texture, and aroma of the foods, heating helps to sterilize and facilitate food storage. On the other hand, heating and thermal processing are frequently reported during the preparation of various traditional herbal medicines. In this review, we intend to highlight works by various research groups which reported on changes in phytochemicals and bioactivities, following thermal processing of selected plant-derived foods and herbal medicines. Relevant cases from plant-derived foods (garlic, coffee, cocoa, barley) and traditional herbal medicines (Panax ginseng, Polygonum multiforum, Aconitum carmichaelii Debeaux, Angelica sinensis Radix) will be presented in this review. Additionally, related works using pure phytochemical compounds will also be highlighted. In some of these cases, the amazing formation of new compounds were being reported. Maillard reaction could be concluded as the predominant pathway leading to the formation of new conjugates, along with other possibilities being suggested (degradation, transglycosylation, deglycosylation and dehydration). With collective efforts from all researchers, it is hoped that more details will be revealed and lead to the possible discovery of new, heat-mediated phytochemical conjugates.

PMID: 28686974 DOI: 10.1016/j.biopha.2017.06.087

For many decades, natural herbal medicines, polyherbal formulations and/or decoctions of plant-derived materials have widely been accepted as alternative complementary therapies for the treatment, cure or prevention of a wide range of acute and chronic skin diseases including chronic herpes, prurigo, acute and chronic wounds, psoriasis and atopic dermatitis (AD). This review was aimed to summarize and critically discuss about the therapeutic viability and clinical applicability of natural herbal medicines for the treatment of AD in human. The critical analysis of the literature revealed that oral (in the form of capsules, syrup or granules) and/or topical application (alone or in conjunction with wet-wrap dressing and/or acupuncture) of natural herbal medicines exhibit remarkable potential for the treatment of mild-to-severe AD in adults, children, infants and in the pregnant women. In this review, the clinical efficacy of various herbal formulations such as Chinese herbal therapies, Korean medicines, Iranian medicines, honey, natural herbal oils (coconut oil, olive oil and mineral oil), beeswax, dodder seeds and whey for the treatment of AD has been discussed. The clinical anti-AD efficacy of these complementary therapies has been observed in terms of down-regulation in Scoring Atopic Dermatitis (SCORAD) index, erythematic intensity, Children's Dermatology Life Quality Index (CDLQI), Dermatology Life Quality Index (DLQI), pruritus and itching frequency, transepidermal water loss (TEWL) and expression of AD-mediated chemokines. Conclusively, we recognized that natural herbal medicines demonstrate remarkable clinical efficacy when used alone or in conjunction with other complementary therapies for the treatment of AD in patients of all ages as well as pregnant women.

Fulltext Investigation of twenty selected medicinal plants from Malaysia for anti-Chikungunya virus activity

Chan YS, Khoo KS, Sit NWW

Int Microbiol, 2016 Sep;19(3):175-182.
PMID: 28494087 DOI: 10.2436/20.1501.01.275

Chikungunya virus is a reemerging arbovirus transmitted mainly by Aedes mosquitoes. As there are no specific treatments available, Chikungunya virus infection is a significant public health problem. This study investigated 120 extracts from selected medicinal plants for anti-Chikungunya virus activity. The plant materials were subjected to sequential solvent extraction to obtain six different extracts for each plant. The cytotoxicity and antiviral activity of each extract were examined using African monkey kidney epithelial (Vero) cells. The ethanol, methanol and chloroform extracts of Tradescantia spathacea (Commelinaceae) leaves showed the strongest cytopathic effect inhibition on Vero cells, resulting in cell viabilities of 92.6% ± 1.0% (512 μg/ml), 91.5% ± 1.7% (512 μg/ml) and 88.8% ± 2.4% (80 μg/ml) respectively. However, quantitative RT-PCR analysis revealed that the chloroform extract of Rhapis excelsa (Arecaceae) leaves resulted in the highest percentage of reduction of viral load (98.1%), followed by the ethyl acetate extract of Vernonia amygdalina (Compositae) leaves (95.5%). The corresponding 50% effective concentrations (EC50) and selectivity indices for these two extracts were 29.9 ± 0.9 and 32.4 ± 1.3 μg/ml, and 5.4 and 5.1 respectively. Rhapis excelsa and Vernonia amygdalina could be sources of anti-Chikungunya virus agents. [Int Microbiol 19(3):175-182 (2016)].

Sit NW, Chan YS, Lai SC, Lim LN, Looi GT, Tay PL, et al.

J Mycol Med, 2018 Sep;28(3):561-567.
PMID: 30060991 DOI: 10.1016/j.mycmed.2018.07.001

OBJECTIVES: This study was conducted to evaluate the antidermatophytic activity of 48 extracts obtained from medicinal plants (Cibotium barometz, Melastoma malabathricum, Meuhlenbeckia platyclada, Rhapis excelsa, Syzygium myrtifolium, Vernonia amygdalina) and marine algae (Caulerpa sertularioides, Kappaphycus alvarezii) against Trichophyton rubrum and Trichophyton interdigitale (ATCC reference strains), and the cytotoxicity using African monkey kidney epithelial (Vero) cells. Active plant extracts were screened for the presence of phytochemicals and tested against clinical isolates of Trichophyton tonsurans.
METHODS: Six different extracts (hexane, chloroform, ethyl acetate, ethanol, methanol and water) were obtained from each plant or algae sample using sequential solvent extraction. The antidermatophytic activity for the extracts was assessed using a colourimetric broth microdilution method. The viability of Vero cells was measured by Neutral Red uptake assay.
RESULTS: All the extracts (except the water extracts of V. amygdalina, C. sertularioides and K. alvarezii) showed antidermatophytic activity against Trichophyton spp. The minimum fungicidal concentration (MFC) ranges for the plant extracts against T. rubrum and T. interdigitale are 0.0025-2.50 and 0.005-2.50mg/mL, respectively. The algae extracts exhibited lower potency against both species, showing MFC ranges of 0.08-2.50 and 0.31-2.50mg/mL, respectively. The ethanol and methanol extracts from the leaves of R. excelsa, and the methanol and water extracts from the leaves of S. myrtifolium were highly active (MFC<0.1mg/mL) and with high selectivity indices (SI>2.8) against reference strains of T. rubrum and T. interdigitale, and most of the clinical isolates of T. tonsurans. Phytochemical analysis indicates the presence of alkaloids, anthraquinones, flavonoids, saponins, tannins, phenolics and triterpenoids in the extracts.
CONCLUSIONS: The medicinal plant extracts exhibited stronger antidermatophytic activity compared to the algae extracts. The leaves of R. excelsa and S. myrtifolium are potential sources of new antidermatophytic agents against Trichophyton spp.
