Abstract:
To study the chemical constituents of Picrasma quassioides. The chemical constituents were isolated and purified by chromatographic methods over Sephadex LH-20 and silica gel column, and structurally elucidated by spectral analysis, including UV, IR, MS, 1H-NMR, 13C-NMR. Fourteen compounds were obtained and identified as trifolirhizin(1), maackiain(2), 3', 7-dihydroxy-4'-methoxylisoflavone(3), umbelliferone(4), emodin(5), nigakilactone F(6), picrasin B(7),picraqualide B (8),4-methoxy-5-hydroxycanthin-6-one(9), 4,5-dimethoxycanthin-6-one (10),5-methoxycanthin-6-one(11), 11-hydroxycanthin-6-one(12) , 1-methoxycarbonyl-beta-carboline(13), 1-hydroxymethyl-beta-carboline(14). Compounds 1-5 are reported from the first time for the genus Pricrasma.
