title: [GC-MS analysis of essential oil from the leaves of Psidium guajava].
abstract: The constituents of essential oils from the leaves of Psidium guajava Linn were analyzed by GC-MS qualitatively and quantitatively. Sixty compounds of the essential oils were identified at rate 90.56%. The major components were caryophyllene (18.81%), copaene (11.80%), [1aR-(1a alpha, 4a alpha, 7 alpha, 7a beta, 7b alpha)]-decahydro-1,1,7-trimethyl-4-methylene-1H-cycloprop[e] azulene(10.27%), eucalyptol(7.36%).
