Chemical constituents of Ammopiptanthus mongolicus
Objective: To study the chemical constituents of aerial parts of Ammopiptanthus mongolicus. Method: Isolation and purification were carried out on silica gel, Sephadex LH-20 and HPLC column chromatography. The structures of the compounds were identified by physico-chemical properties and spectral analysis. Result: Nine compounds were isolated and identified as ( + )-maackiain (1), brevifolin (2), 7-hydroxy-4′-methoxy isoflavanone (3), daidzein 4′,7-diglucoside (4), genistein 4′,7-di-O-β-D-glucoside (5), isolupalbigenin (6), ononin (7), β-sitosterol (8), β-daucosterol (9). Conclusion: Compounds 2,4 ～ 6 were obtained from the genus Ammopiptanthus for the first time.
