Separation and identification of a kind of triterpenoid saponin from the husks of Xanthoceras sorbifolia Bunge
Abstract:AIM: In order to explore new medicine part and resource of medicine, triterpenoid saponins in the husks of Xanthoceras sorbifolia Bunge were studied. METHODS:The constituents were isolated by silica gel column chromatography, D101 macroporous resin column chromatography and semi-preparative liquid chromatography, and their structures were elucidated by 1H-NMR,13C-NMR. RESULTS: A kind of triterpenoid saponin was isolated from the husks of Xanthoceras sorbifolia Bunge, which was identified as 3-O-(3-O-angeloyl-6-O-β-D-glucopyranosyl)-β-D-glucopyranosyl-28-O-(2-α-L-rhamnopyranosyl-6-O-β-D-glucopyranosyl)-β-D-glucopyranosyl-16-deoxybarringtogenol C. CONCLUSION: Our experiment provided a fundamental reference for the development of the medicine resource of Xanthoceras sorbifolia Bunge.
Keywords: Chinese materia medica husks of Xanthoceras sorbifolia Bunge triterpenoid saponin
