METHODS: In the present study, the dried roots of Hemidesmusindicus were crushed to a coarse powder and extracted with water under reflux for 36 hours to obtain the aqueous extract of roots of Hemidesmusindicus (AERHI). The extract was reconstituted in 2% aqueous tragacanth just before use and administered orally at a dose 0f 100 mg/kg, 300 mg/kg and 500 mg/kg. In a single dose study, the parameters were assessed after oral administration of the single dose of the AERHI, whereas in a multiple dose study, the animals daily received the suitable oral dose of the AERHI for a period of 30 days. The parameters were assessed on the 15th and 30th day. The antipsychotic activity was screened using Apomorphine induced Stereotyped behavior in rats and Haloperidol induced catalepsy models were used. In Apomorphine induced Stereotyped behavior inhibition of the Stereotyped behavior was considered to be anti-psychotic activity and in Haloperidol induced catalepsy, we observed whether the AERHI potentate or attenuate the catalepsy in rats.
RESULTS: In this study, the extract of Hemidesmusindicus significantly inhibited the stereotyped behavior induced by apomorphine in rats and also potentiate the catalepsy induced by haloperidol, thereby showing its anti-psychotic activity.
CONCLUSION: All these observations imply that Hemidesmusindicus extract possesses anti-psychotic activity in experimental animals.
OBJECTIVE: This review was aimed to critically overview the literature and summarizes the antibacterial, antiprotozoal, and antifungal trends of E. longifolia and its medicinally active components.
RESULTS: Besides its well-documented safety, efficacy, and tolerability, a plethora of in vitro, in vivo, and human clinical studies has evidenced the antimicrobial efficacy of E. longifolia and its bioactive constituents. Phytochemical screening of various types of extracts (methanolic, ethyl acetate, and nbutanolic) from different parts (roots, stem, and leaves) of E. longifolia displayed a dose-dependent antibacterial, antiprotozoal, and antifungal responses. Comparative analysis revealed that the root extract of E. longifolia exhibited the highest antimicrobial efficacy compared to other parts of the plant. Bioactivity-guided fractionation identified that among all of the medicinal compounds isolated/ extracted from different parts of E. longifolia, eurycomanone displayed the strongest antibacterial, antiprotozoal and antifungal activities.
CONCLUSION: Based on the critical analysis of the literature, we identified that E. longifolia exhibits promising antibacterial, antiprotozoal, and antifungal efficacies against various pathogenic microbes and thus can be considered as a potential complementary and alternative antimicrobial therapy.
