薯蓣皂甙元(diosgenin)是合成甾体激素药物的重要原料。它主要是从薯蓣属(Dioscorea)植物的根茎中提取的。测定植物材料中薯蓣皂甙元的含量通常采用重量法,操作繁琐费时,样品需量较大,不适宜大量样品的筛选。同时,由于操作条件掌握上的差异,容易造成较大的误差。六十年代以来,气液色谱(GLC)应用于甾体化合 Diosgenin is an important raw material for the synthesis of steroid hormone drugs. It is mainly extracted from the roots of Dioscorea plants. Determining the content of diosgenin in plant material usually adopts the gravimetric method, and the operation is cumbersome and time-consuming, and the sample requires a large amount, which is not suitable for the screening of a large number of samples. At the same time, due to differences in the operating conditions, it is easy to cause large errors. Since the 1960s, gas liquid chromatography (GLC) has been applied to the corpus callosum
