Investigation of in Vitro Anthelmintic activity of Azadirachta Indica Leaves
HAQUE RABIU, MONDAL SUBHASISH
The aqueous extract of Azadirachta Indica Leaves was investigated for anthelmintic activity using earthworms (Pheretima posthuma), tapeworms (Raillietina spiralis) and roundworms (Ascaridiagalli). Various concentrations (10-70 mg/ml) of plant extract were tested in the bioassay. Piperazine citrate (10 mg/ml) was used as reference standard drug whereas distilled water as control. Determination of paralysis time and death time of the worms were recorded. Extract exhibited significant anthelmintic activity at the concentration of 40 mg/ml. The result shows that aqueous extract possesses vermicidal activity and found to be effective as an anthelmintic. Therefore, the anthelmintic activity of the aqueous extract of Azadirachta Indica Leaves has been reported
