摘要:

从中药红芪中首次发现一个不稳定化合物。在该化合物稳定性研究的基础上, 采用酸性甲醇作为提取溶剂, 在HPLC指导下快速分离得到该不稳定化合物, 并利用现代波谱技术鉴定其结构为芒柄花素 7-O-β-D-(6''-O-丙二酸单酰基)-吡喃葡萄糖苷, 本文是首次报道从红芪及岩黄芪属植物中分离得到该化合物。

关键词: 红芪, 芒柄花素7-O-β-D-(6''-O-丙二酸单酰基)-吡喃葡萄糖苷, 异黄酮苷丙二酸酯

Abstract: Based on the stability results of Radix hedysari extract, an unstable compound was extracted using acidic methanol and purified by rapid chromatographic methods successfully from Radix hedysari for the first time guided by HPLC analysis. Its structure was identified as formononetin 7-O-β-D-(6''-O-malonyl)-glucopyranoside by spectroscopic analyses.

Key words: Radix hedysari, Formononetin 7-O-β-D-(6''-O-malonyl)-glucopyranoside, Isoflavonoid glycoside malonate
