摘要

Agarwood, also known as 'chenxiang' in Chinese, is the fragrant resinous heartwood obtained from certain trees of the genus Aquilaria (Malvales: Thymelaeaceae). Being a highly valuable non-timber product from Asian tropical forests, agarwood is used for incenses, perfumes and traditional medicines. Studies showed that the chemical constituents of agarwood are sesquiterpenes, 2-(2-phenylethyl)chromones, aromatics, triterpenes, etc.[1,2] The most abundant constituents in agarwood have been found to be 2-(2-phenylethyl)chromones (41%) and sesquiterpenes (52%).[1] Among which, 2-(2-phenylethyl)chromones are considered to be the major group of constituents responsible for the quality of agarwood and were found to possess neuroprotective,[3] cytotoxic,[4,5] antiallergic activities,[6] etc. It is obvious that detection and structure characterization of the main constituent, 2-(2-phenylethyl)chromones are key to the qualification of agarwood.
