Abstract: Cymbopogon flexuosus (Nees ex Steud) Wats commonly known as, East Indian lemongrass a widely grown essential oil plant in the world belongs to the family Poaceae and comprise of 140 species worldwide, found abundantly in tropics and sub-tropic regions of Asia, Africa and America. In India, 45 species are recorded of which the economic importance is C.winterianus, C.flexuosus, C.martinii, C.nardus, C.citratus, C.pendulus, C.jwarancusa and C.khasianus. Aerial and sub-aerial parts of C. flexuosus collected from Himavath Gopala hills, Karnataka, India, were subjected to hydrodistillation for extraction of essential oil. GC and GC-MS analysis were performed to know the chemical composition of the oil. Among the 39 compounds identified in aerial parts of the plant the major compounds were citral (64.98%), 1,7-octadien-3-ol (10.97%), dimethyl oxatricyclo nonanone (9.44%), nerol (2.85%), verbenol (1.77%) and caryophyllene oxide (0.71%). In sub-aerial parts of the plant 33 compounds were identified. The analysis of sub-aerial parts showed a different chemical profile compared to aerial part and possessed citral as the major compound of upto 30.47%. Other compounds in sub-aerial part are Eudesmol (17.82%), Elemol (14.16%), dihydro isopropyl methyl azulene (11.08%), .-cadinene (1.88%), junipene (1.36%), hydroxyalloaromadendrene, juniper camphor (1.12%) and elemene (1.04%).
