Comparative In vitro Anthelmintic Activity of Mentha piperita and Lantana camara from Western India

Abstract

Methanol extracts from the leaves, stems and roots of Mentha piperita and Lantana camara were investigated for their anthelmintic activity against Pheritima posthuma. Each extract was studied in the bioassay at 20 mg/ml, which involved determination of time of paralysis and time of death of the worms. Both the extracts of both plants exhibited considerable anthelmintic activities, and the order of sensitivity of the extracts to the worms was stems > roots > leaves for the M. piperita and stems > leaves >roots for the L. camara. The methanol extracts of stems of both M. piperita and L. camara were found to be the most active. Albendazole (20 mg/ml) and distilled water were included in the assay as standard reference drug and control, respectively.
