从异叶败酱（ＰａｔｒｉｎｉａｈｅｔｅｒｏｐｈｙｌｌａＢｇｅ．）地上部分甲醇提取物中分得２个黄酮类化合物，经光谱分析与化学方法鉴定为：金丝桃甙（Ⅰ），异槲皮甙（Ⅱ），这２个化合物在败酱科植物中均是首次报道。
Two flavonoids were isolated from the above-ground methanol extract of Patrinia heterophylla Bge. The results were confirmed by spectral analysis and chemical analysis: Hypericum perforatum (I) and isoquercitrin (II). The compounds were first reported in Paeniaceae.
