目的 研究粉背南蛇藤醋酸乙酯部位的黃酮類化合物。方法 利用正相、反相硅膠和凝膠色譜柱分離技術(shù)分離制備，通過理化性質(zhì)和核磁共振、質(zhì)譜等波譜數(shù)據(jù)鑒定化合物的結(jié)構(gòu)。結(jié)果 分離鑒定了4個化合物，分別為大豆素（1）、表沒食子兒茶素（2）、沒食子兒茶素（3）、大豆素-7-O-β-D-吡喃葡萄糖苷（4）。結(jié)論 所有化合物均為首次從該植物中分離得到。

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.
