Abstract

We undertook the present study to evaluate different pharmacological as antioxidant, antibacterial and cytotoxic activities of the crude ethanolic extract of Momordica charantia (Family: Cucurbitaceae) leaves. The antioxidant property of the extract was assessed by 1, 1-diphenyl-2-picryl hydrazyl free radical scavenging assay. The extract showed antioxidant activity where $IC_{50}$ was about ${\sim}500{\mu}g/ml\;and\;IC_{50}$ was about ${\sim}10{\mu}g/ml$ for standard drug ascorbic acid. The extract showed a broad spectrum of antibacterial activity against all the tested gram positive and gram-negative bacteria where Staphylococcus epidermidis, Staphylococcus aureus, Salmonella typhi and Shigella dysenteriae were prominent. And the zones of inhibition were ranging from 8-15 mm for all the tested bacteria. Its cytotoxic property was evaluated by brine shrimp lethality bioassay. The extract showed significant lethality and the $LC_{50}$ value was $20{\mu}g/ml$.
