Abstract:  In order to understand the chemical constituents of Spatholobus suberectus Dunn, 15 phenolic constituents were obtained from 95% EtOH extract of S. suberectus stems by chromatographic separation methods. On the basis of spectral data, they were identified as gallic acid (1), tachioside (2), isotachioside (3), canthoside D (4), koaburaside (5), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (6), 4-hydroxymethyl-2,6- dimethoxyphenyl-β-D-glucopyranoside (7), glucosyringic acid (8), 3-methoxyphenethyl alcohol-4-O-β-Dglucopyranoside (9), 2-(4-hydroxy-3,5-dimethoxyphenyl)ethyl-β-D-glucopyranoside (10), 4,6-dihydroxy-2-O- (β-D-glucopyranosyl)-acetophenone (11), rosin (12), cis-syringin (13), (-)-(7R,8S)-guaiacylglycerol 8-O-β-Dglucopyranoside (14), and l-threo-guaiacylglycerol-8-O-β-glucopyranoside (15). Among them, compounds 2 - 8 and 10 - 15 were isolated from the Spatholobus genus at first time.
