Abstract:Seven chemical constituents from fruits of Aquilaria sinensis (Lour.) Gilg were isolated by column chromatography. Based on spectral analysis and physicochemical evidence, their structures were identified as: indolyl-3-carboxylic acid (1), 6-hydroxy-2-[2-(4-hydroxyphenyl)ethyl] chromone (2), genkwanin (3), 4',5-dihydroxy-3',7-dimet-hoxyflavone (4), apigenin-7,4'-dimethylethers (5), β-sitosterol (6), and daucosterol (7). Compound 1 was obtained from the genus Aquilaria of the family Thymelaeaceae for the first time.
