Abstract

Five compounds were obtained from the stems and leaves of Sophora flavescens Ait. and ten compounds were obtained from the roots of S. flavescens by various chromatography methods including silica gel column chromatography and preparative HPLC. Their structures were identified on the basis of spectroscopic methods including 1H-NMR, 13C-NMR and ESI-MS, as corchionoside C (1), syringing (2), 2'-deoxythymidin (3), coniferin (4), benzyl O-beta-D-glucopyranoside (5), piscidic acid (6), trifolirhizin (7), kurarinone (8), trifolirhizin-6'-monoacetate (9), sophoraflavanone G (10), isoxanthohumol (11), noranhydroicaritin (12), 4'-methoxyisoflavone-7-O-beta-D-apiofuranosyl-(1 --> 6)-beta-D-glucopyranoside (13), kushenol O (14) and 6"-beta-D-xylopyranosylgenistin (15). Compounds 1-6 were isolated from the Sophora genus for the first time.
