中国药典1977年版对一些含皂甙药材未收载化学鉴别方法,仅对少数品种采用泡沫试验鉴别。这种方法缺乏专属性。为了更好的鉴别这些药材,笔者通过某些化学实验进行鉴别,效果较满意,现报道如下。药材与试剂1.药材:远志、皂荚、紫菀、合欢皮、党参、桔梗、粉萆薢、连翘。均为当地医药公司购进。2.试剂:硫酸、无水乙醇、95%乙醇、正丁醇、高锰酸钾(以上分析纯)。香草醛(化学纯)。硅胶G(制备薄层板,北京化工厂产)。72%(V/V)硫酸溶液(取
The Pharmacopoeia of the People’s Republic of China published in 1977 did not collect chemical identification methods for some saponin-containing medicinal materials. Only a few varieties were identified by the foam test. This method lacks specificity. In order to better identify these herbs, the author identified through some chemical experiments, the effect is more satisfactory, now reported as follows. Medicinal materials and reagents 1. Medicinal materials: Polygala, acacia, Aster, Albizia julibrissin, Codonopsis, Campanulaceae, whitefly, forsythia. Purchased by local pharmaceutical companies. 2. Reagents: sulfuric acid, anhydrous ethanol, 95% ethanol, n-butanol, potassium permanganate (above analytical grade). Vanillin (chemically pure). Silicone G (preparation of thin plates, produced by Beijing Chemical Plant). 72% (V/V) sulfuric acid solution (take
