目的:研究苦豆子的酚性成分。方法:采用溶剂萃取和各种色谱方法对苦豆子95%乙醇提取物的非生物碱部分进行分离纯化,利用波谱学方法鉴定化学成分的结构。结果:分离得到了7个化合物。分别为:阿魏酸(1),紫铆因(2),7,3,′4′-三羟基黄酮(3),7-羟基-3,′4′-二氧亚甲基异黄酮(4),紫铆因-4′-O--βD-吡喃葡萄糖苷(5),番石榴酸(6)和7,3,′4′-三羟基黄烷-7-O--βD-吡喃葡萄糖苷(7)。结论:以上所有化合物均为首次从苦豆子中分离得到。 Objective: To study the phenolic components of Sophora alopecuroides. METHODS: The non-alkaloid fractions of 95% ethanol extract of Sophora alopecuroides were isolated and purified by solvent extraction and various chromatographic methods. The structures of chemical constituents were identified by spectroscopic methods. Results: Seven compounds were isolated. They are: ferulic acid (1), buterin (2), 7,3, ’4’-trihydroxyflavone (3), 7-hydroxy-3,’4’-dimethoxymethylene isoflavone ( 4) Butestine-4′-O-βD-glucopyranoside (5), guavadic acid (6) and 7,3′′4′-trihydroxyflavan-7-O-βD- Glucopyranoside (7). Conclusion: All the above compounds were isolated from Sophora alopecuroides for the first time.
