Biochanin A is one of the most common phytoestrogens, occurring in high concentrations in soy and red clover, for instance, which shows a wide spectrum of biological activity. Prunetin is an isomer of biochanin A, and even though it is not very common, its structural relationship to the latter makes it interesting, regarding its biological activity. Nowadays, LC/ESI-MS methods are widely used for identification of natural compounds, including biochanin A and prunetin. However, we found that the published data concerning the identification of biochanin A and prunetin are sometimes disputable. Namely, the identification is based on the product ions which cannot be regarded as characteristic of biochanin A or prunetin. The reported retention times sometimes may be also disputable.

评论有关通过LC / ESI-MS鉴定生物chanin A和普鲁宁的公开数据。
Biochanin A是最常见的植物雌激素之一，例如以高浓度存在于大豆和红三叶草中，表现出广泛的生物活性。普鲁京汀是生物chanin A的一种异构体，尽管它不是很常见，但就其生物学活性而言，其与后者的结构关系使其变得有趣。如今，LC / ESI-MS方法已广泛用于鉴定天然化合物，包括生物chanin A和普鲁涅汀。但是，我们发现有关生物素A和果胶素鉴定的公开数据有时存在争议。即，鉴定是基于不能被认为是生物松弛素A或普鲁宁的特征的产物离子。报告的保留时间有时也可能会引起争议。
