Abstract:
Objective To study the chemical constituents of Astragalus membranaceus var. mongholicus. Methods The constituents were isolated and purified by several chromatographic techniques and identified by chemicophysical properties and spectral analyses. Results Nine flavonoid compounds had been obtained from A. membranaceus var. mongholicus. They were determined as formononetin (Ⅰ), (3R)-8, 2′-dihydroxy-7, 4′-dimethoxy-isoflavane (Ⅱ), calycosin (Ⅲ), (6aR, 11aR)9, 10-dimethoxypterocarpan-3-O-?-D-glucoside (Ⅳ), 7, 2′-dihydroxy-3′, 4′-dimethoxy-isoflavane-7-O-?-D-glucoside (Ⅴ), formononetin-7-O-?-D-glucoside (Ⅵ), calycosin-7-O-?-D-glucoside (Ⅶ), pratensein-7-O-?-D-glucoside (Ⅷ), and genistin (Ⅸ), respectively. Conclusion Compound Ⅷ is obtained from the plants of Astragalus Linn. for the first time and compound Ⅱ is obtained from this plant for the first time. Compounds Ⅰ-Ⅶ show cell multiplication activity.
