Abstract :
Different extracts of piper betle were taken for anthelmintic activity against Indian earthworm Pheretima Posthuma Two concentrations (20 and 40 mg/ml) of various extracts were tested and results were expressed in terms of time for paralysis and time for death of worms. Albendazole (20 mg/ml) was used as reference standard and carboxymethyl cellulose (0.5%) as a control group. Paralysis time can be determined by vigorous shaking when no movement was observed. When whitish substances were secreted from the body that one was termed as death time. Dose dependent activity was observed in the plant extracts but pet. Ether extract exhibited more activity as compared to others.
