abstract the essential oils obtained by hydrodistillation of the leaves, bark and fruits of neolitsea fischeri were analyzed by gc and gc/ms. twenty components comprising 80.3% of the leaf oil, twenty-six components comprising 94.7% of the bark oil and twenty-seven components comprising 78.8% of the fruit oil were identified. the major components in the leaf oil were caryophyllene oxide (33.0%) followed by selin-11-en-4-ol (14.8%). the bark oil contained 10.2% cadinene and two isomers of cadinol viz. -cadinol (24.5%) and -muurolol (22.2%) as the major components, while the fruit oil had -cadinol (19.9%) and caryophyllene oxide (13.7%) as the major components. the fruit, leaf and bark oils showed moderate to good activity against some of the tested gram-positive and gram-negative bacteria key word index: neolitsea fischeri lauraceaeessential oil composition-cadinol-muurolol-cadinenecaryophyllene oxideselin-11-en-4-olantibacterial activity
