目的：研究传统中药复方肠胃康中的黄酮类成分。方法：采用多种柱色谱对复方肠胃康进行分离纯化，利用理化性质和波谱数据鉴定化合物的结构。结果：从复方肠胃康中分离得到5 个黄酮类化合物，分别鉴定为槲皮素（1）、山奈酚-3-O-芸香糖苷（2）、芦丁（3）、山奈酚（4）和洋芹素（5）。结论：化合物1-5 均为首次从该复方中分离得到黄酮类化合物。

This work aimed to study the chemical constituents of flavonoids in the prescription Changweikang. The constituents were isolated by various column chromatographies and their structures were elucidated through physicochemical properities and spectroscopic analysis. Five flavonoids were isolated from Changweikang and their structures were identified as Quercetin (1), Kaempferol-3-O-rutinoside (2), Rutin (3), Kaempferol (4) and Apigenin (5). Compounds 1-5 were obtained from the prescription Changweikang for the first time.
