Anthelmintic and Preliminary Phytochemical Screening of Nymphaea nouchali Burm.f. Against Intestinal Helminthiasis

Extracts from the thalamus of Nymphaea nouchali Burm.f. were investigated for their anthelmintic activity against Pheretima posthuma. Various concentrations (5–20 mg/ml) of each extract were tested in the bioassay, which involved determination of time of paralysis time of death of the worms. The activity of Chloroform and alcoholic extracts were found to be more significant than both the standards even at a dose of 10mg/ml. Piperazine xitrate and Albendazole (10mg/ml) were included as standard references and distilled water as control.
