Abstract: A phytochemical study of the ethyl acetate extract (EtOAc) of Styrax annamensis leaves resulted in the isolation and determination of six known compounds, including three nor-neolignans type 2-phenylbenzofurans egonol (1), egonoic acid (2) and (-)-machicendiol (3), two lignans styraxin (4) and vladinol D (5), and a triterpenoid pomolic acid (6). The Chemical structures of these compounds were determined by NMR spectroscopies, and MS data. This is the first time to isolate these compounds from S. annamensis species. Compounds 3 and 5 have also been observed from genus Styrax for the first time.
