目前,直接由原植物中测定某一黄酮甙类化合物还未见有专一方法报导,因此,烈香杜鹃中棉子皮亭甙的含量至今亦未找到合适的方法进行测定。最近我们试用文献上报告的用于测定薄荷脑的内标薄层定量法进行了探讨,初步获得成功,现将原理和具体操作报告如下。 At present, the determination of certain flavonoid glycosides directly from the original plant has not yet been reported in a specific way. Therefore, the content of pilose quinone in P. sinensis has not been found yet. Recently, we examined the thin layer internal standard method for measuring menthol, which was reported in the literature, and discussed the preliminary results. The principle and specific operations are reported below.
