Abstract

PlanThe present study was undertaken for investigating and scientifically validating the traditional claims of Clerodendrum paniculatum Linn   for its therapeutic activity.

MethodologyPhytochemical screening demonstrated the presence of carbohydrates, glycosides, and tannins and Phenolic compounds in methanolic and aqueous extracts and sterols in all the extracts used. The brine shrimp toxicity assay was carried out on Petroleum ether, Chloroform, Ethyl acetate, Methanol and aqueous extracts using standard procedure. Brine shrimp assay (BSA) test showed   LC50 of 400, 1600, 1700, and 1700 µg for the Petroleum ether, Chloroform, Ethyl acetate, Methanol extracts respectively. The degree of lethality was found to be directly proportional to the concentration of the extract. Maximum mortality rate of 100% was observed in the petroleum ether extract at 1600µg/ml while least mortality was observed in methanolic extract of 100 and 200µg/ml and 10% at 400 and 800µg/ml 

Outcome: In summary petroleum ether extract has the highest mortality rate than compared to methanolic extract. The methanolic and chloroform extracts of the leaves of C.paniculatum showed effective antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans.
