Fresh leaf material of Syzygium benthamianum a vulnerable tree species endemic to India, was steam distillation and analyzed by GC-MS for its chemical composition. The essential oil contained a total of 63 compounds. The major compounds obtained were sitosteryl acetate (11.83 %), stigmastan-3,5,22trien (7.0 %), 2,6-dimethyl-2-octene (6.99 %), estra-1,3,5(10)-trien-17.beta.-ol (6.3 %), ergosta-4,7,22-trien3.beta-ol (5.19 %), 1-methylcholest-1,3,5(10)-trien-3-ol (5.06 %) and a number of other minor compounds. This is the first report of essential oil chemical composition from leaf materials of S. benthamianum from India.
