Abstract: Chaerophyllum villosum Wall. ex DC (C. villosum) is widely distributed in east Asia Himalayas from India to Bhutan, Nepal and China and widely grows in moist shady places, road sides or open grassy places at elevations of 2100-3500 m. The present study investigates the chemical composition of essential oil isolated from the roots of C.villosum. The essential oil was hydro distilled   and isolated essential oil was analyzed by Gas Chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS).Chemical composition analysis of root essential oil led to the identification of 31 constituents accounting for 91.49% of the total oil composition. The carvacrol methyl ether (31.12 %), myristicin (19.06 %), thymol methyl ether (18.60 %), γ-terpinene (11.69 %), were the principle components.
