Investigation of anthelmintic potential of some plants claimed by tribals of Satpuda Hills.

Abstract

The aqueous extract of Cassia auriculata leaves (Awali), Erythrina variegate leaves (Pangora) and Dioscorea bulbifera bulbs(Kand) were investigated for their anthelmintic potential against earthworms (Eicinia faeteda), tapeworms(Raillietina spiralis) and roundworms(Ascardia galli). Various concentrations (10-50 mg/ml) of each plant extract were tested in the bioassay and different parameters such as determination of time of paralysis and time of death of the worms were recorded. All the extracts exhibited significant anthelmintic activity at highest concentration of 50 mg/ml. Piperazine citrate (10 mg/ml) was used as reference standard and distilled water as control.
