ABSTRACT
Sample of Pingle Jiegu Dan was extracted with methanol, n-butyl ethanol and absorbed with coarse-hole resin, and its total saponin content of notoginseng was determined with spectrophotometry. The result was reproducible. This method effectively excludes the interferential elements in a complex preparation and can be employed as a method for quantitative analysis. Meanwhile, it also provides a reference for the quantitative analysis of preparation containing notoginseng.
