知母是一种常用中药。化学成分生要为皂甙类,其皂甙元主要是菝葜皂甙元,曾有报道用双波长薄层扫描法测其皂甙元含量,但考查认为该法水解不易完全,测定值低。经反复实验建立了一种水解完全的方法。并对全国不同省市,
Anemarrhenae is a commonly used traditional Chinese medicine. The chemical constituents are saponins, and the saponins are mainly saponins. The content of saponins was measured by the dual-wavelength thin-layer scanning method.

And for different provinces and cities across the country,
