Abstract
Phyllanthus acidus is commonly known as gooseberry tree belongs to family Phyllanthaceae which usually grow in tropical areas. In order to establish its functional activities, the antioxidant, phenolic content, antibacterial and molluscicidal activities of the plant were assessed. P. acidus aqueous extract showed 57.14 % radical scavenging activity and contained 29. 41 mg GAE/ g total phenolics. The bacterial inhibitory activity of P. acidus hot water extract against E. coli and S. aureus showed a mean diameter zone of inhibition of 0.58 mm and 5. 19 mm respectively. Whereas, the aqueous extract showed no bacterial inhibitory activity against the bacterial pathogens. Meanwhile, the molluscicidal activity of P. acidus against Pomacea canaliculata (golden apple snail) showed that the extract with a concentration of 1000 ppm had a mean of 2.38 which showed the highest mean mortality rate among the three concentration of aqueous extract tested. Results of the screening of functional activities of the plant extract showed a continuous effort to find a new pharmacological potentiality and plant molluscicides
