水曲柳与常用中药秦皮是同科同属植物,是秦皮的常见伪品。是否能够代替秦皮入药,经过分析,发现水曲柳树皮不含有与秦皮(主要含有秦皮甲素及乙素)相同的有效成分,而主要含有一种6—羟基—5.7—二甲氧基香豆素(Fraxinol),不能代替秦皮入药,应视为伪品。 Fraxinus mandshurica and commonly used traditional Chinese medicine, Qinpi, belong to the same genus and belong to the same family. It is a common counterfeit product of Qinpi. Whether it can be used as a substitute for Qinpi, after analysis, it was found that the bark of Ash does not contain the same active ingredients as Qinpi (mainly containing aesculin and B), but mainly contains a 6-hydroxy-5.7-dimethoxy-coumar. Fraxinol, which cannot be used as a substitute for Qinpi, should be regarded as a fake.
