There is a continuous search for alternative source of medicines particularly from plants. The study aimed to evaluate the anthelmintic activity of aqueous, methanol, acetone and petroleum crude extracts of Tridax procumbens. The aqueous, methanol, acetone and petroleum extracts of the dried powder of Tridax procumbens whole plant was extracted . The extract collected were screened for preliminary phytochemical studies and also tested for Anthelmintic activity against Indian adult earthworm Pheritima posthuma (Annelida) and recorded the time taken for induction of paralysis and death. Three concentrations (10,30,50 mg/ml) of all the form were evaluated in the bioassay involving determination of time of paralysis (P) and time of death (D) of the worms. Albendazole suspension (10 mg/ml) was used as reference standard. Comparative results of present study indicated that the methanol and acetone extracts of Tridax procumbens linn shows significantly dose depending pharmacological activity on the Indian earthworms.Extract possessed wormicidal activity and thus, may be useful as an anthelmintic.
