红花岩黄芪新天然产物研究

目的：研究红花岩黄芪 Hedysarum multijugum Maxim. 的化学成分。方法：采用溶剂法和各种色谱技术进行分离，根据化合物的理化性质以及多种谱学数据鉴定其结构。结果：从红花岩黄芪根中分离鉴定了7个化合物，分别为 warangalone-4′-methyl ether（1），阿佛洛莫生（2），5，7-二羟基-4′-甲氧基异黄酮-7-O-β-D-葡萄糖苷（3），芒柄花素苷（4），柚皮素-5，7-二-O-葡萄糖苷（5），芹菜素（6）和水仙苷（7）。 结论：化合物 1 是新天然产物，其余化合物为首次从该植物中分离得到。

Objective: To study the chemical constituents of the roots of Hedysarum multijugum Maxim. Methods: Compounds were isolated and purified by solvent and column chromatographic methods, and their structures were determined on the basis of physico-chemical properties and spectroscopic data. Results: Seven compounds warangalone-4′-methyl ether(1), afrormosin (2), sissotrin (3) and ononin (4), naringenin-5, 7-di-O-β-D-glucopyranoside (5), apigenin (6) and narcissin (7) were obtained from the roots of Hedysarum multijugum. Conclusion: Compound 1 is a new natural product, and other compounds; are obtained from the plant for the first time.
