title: [Sesquiterpenes and monoterpene from Aquilaria sinensis].
abstract: The column chromatography on silica gel, semi-preparative HPLC were used to separate and purify the compounds from the petroleum ether and ethanol extract of Aquilaria sinensis. Nine compounds were isolated. On the basis of their spectroscopic data, the structures were identified as 3, 3, 7-trimethyltricycloundecan-8-one (1), longifolene (2), norlongilactone (3), caryophyllenol-II (4), humulene diepoxide A (5), kobusone (6), (-)-bornyl ferulate (7), (24R) -24-ethylcholesta-4, 22-dien-3-one (8), (24R)-24-3-ono-4-en-sitosterone (9). Compounds 2-9 were isolated from this plant for the first time. compounds 1-6 are sesquiterpenes, compound 7 is a monoterpene derivative, compound 8 and 9 are steroids.
