The main aim of the study was to investigate phytoconstituents and anti-helminthic activity in the canthium parviflorum root. Roots were collected and shade dried. Extraction was carried out by continues hot percolation method using ethylacetate and methanol as solvents. Both the extracts were subjected to phytochemical screening, using standard methods, where as anti-helminthic activity was evaluated at three different concentrations on Pheretima Postuma; the parameters like time of paralysis and time of death were determined. The extract showed significant activity in the dose dependent manner and methanolic root extract showed significant activity than that of standard drug Albendazole. This might due to the presence of secondary metabolite tannins which are responsible for the activity.
