目的 研究粉背南蛇藤醋酸乙酯部位的黄酮类化合物。方法 利用正相、反相硅胶和凝胶色谱柱分离技术分离制备，通过理化性质和核磁共振、质谱等波谱数据鉴定化合物的结构。结果 分离鉴定了4个化合物，分别为大豆素（1）、表没食子儿茶素（2）、没食子儿茶素（3）、大豆素-7-O-β-D-吡喃葡萄糖苷（4）。结论 所有化合物均为首次从该植物中分离得到。

Objective To determine the flavonoids in acetic ether extract fraction from Celastrus hypoleucus. Methods Chemical constituents were isolated and purified by silic gel and Sephadex LH-20 column chromatography，and their structures were elucidated by chemical and spectroscopic methods. Results Four compounds were identified as daidzein (1), epigallocatechin (2), gallocatechin (3), and 4'-hydroxyflavone 7-O-β-D-glucopyranoside (4). Conclusion All compounds are isolated from this plant for the first time.
