An evaluation of anthelmintic activity of Ricinus communis Linn. leaves by using different type of solvent

Abstract

Aqueous and ethanol ethyl actatate chloroform methanol extracts from the leaves of Ricinus communis were investigated for their anthelmintic activity against Pheretima posthuma and three concentrations (50, 75 and 100 mg/ml) of each extract were studied for activity, in which paralysis and death time of the worm. Both the extract exhibited remarkable anthelminthic activity at all three concentrations. Albendazole suspension is used as standard reference (20mg/ml) and distilled water as control. Therefore the aqueous and ethanol methanol extract of leaves of Ricinus communis has been demonstrated for the first time.
