The present communication deals with the comparative studies on anthelmintic potential of methanolic and aqueous extracts of Cymbopogon citratus and Wrightia tinctoria against Pheritima posthuma. Methanolic and aqueous extracts of both were used as test solutions. Piperazine citrate was used as standard drug and normal saline as a control. Study involved the determination of time of paralysis as well as time of death of worms. The results revealed that methanolic extract of Cymbopogon citratus leaves have better anthelmintic activity than that of Wrightia tinctoria extracts. Further it will be interesting to isolate the active chemical constituents from both the plants
