Suman D, Vishwanadham Y, Kumaraswamy T, Shirisha P and Hemalatha K

In the present study, different solvent extracts of “Pentas lanceolata” leaves (family Rubiaceae) were under taken for phytochemical investigation and subjected to analgesic activity. The preliminary and phytochemical investigation showed presence of sterols, triterpinoids, glycosides, flavonoids, alkaloids, carbohydrates, resins. The different solvent like n-Hexane, ethyl acetate, ethanolic extracts of compounds from “Pentas lanceolata” leaves. Analgesic activity was performed by the acetic acid induced writhing method. Due to the presence of the above compounds in n-hexane and ethanol extracts showed significant activity (P<0.01) when compared with the standard (aspirin) whereas ethyl acetate extract showed moderate to weak (P<0.05) activity.
