syzygium cumini (l.) skeels (jambolan) is a widespread summer fruit plant, well-known for various therapeutic uses such as anti-diabetic, antimicrobial, antioxidant properties. the fruit helps to convert starch into energy which helps in regulating blood sugar levels and possesses a low glycemic index. the present study is aimed to estimate the chemical composition of the essential oil of leaves of syzygium cumini through gc/ms. the essential oil was extracted by hydrodistillation using a clevenger apparatus which was further analyzed through gc/ms. the gc/ms analysis identified twenty-five components with a total area percentage of 95.66 %. the major identified components were -cadinol (21.44 %) and tau-muurolol (12.01 %). the compounds of intermediate concentration were globulol (7.98 %), caryophyllene (6.69 %), -cadinene (6.56%) and -pinene (6.32 %). while -eudesmol (4.42 %), -pinene (4.32 %), -cadinene (3.87 %), camphene (2.98 %), -terpinenol (2.72 %), camphor (2.23 %), humulene 6,7-epoxide (2.17 %), cubeban-11-ol (1.98 %), -muurolene (1.81 %), epicubenol (1.43 %), -copaene (1.26 %), viridiflorene (1.02 %), -guanine (0.65 %), -bourbonene (0.23 %), terpinen-4-ol (0.13 %), endo-borneol (0.12 %), levoverbenone (0.12 %) and isobornyl acetate (0.12 %) were the compounds present in minor concentrations. among the identified compounds there were monoterpene hydrocarbons (13.62 %), bicyclic-monoterpenoid (0.36 %), terpenoid ketones (2.23 %), monocyclic monoterpenoid alkene alcohol (2.85 %), non-oxygenated sesquiterpenes (25.17 %) and oxygenated sesquiterpenes (51.43 %). the present investigation also discusses the applications of various components found in s. cumini leaf essential oil and a comparative view on the essential oil composition of the leaves of the plant was reported earlier.
