Method for detecting characteristic chromatograms of radix knoxiae, vinegar radix knoxiae and preparations of radix knoxiae and vinegar radix knoxiae

The invention provides a method for detecting characteristic chromatograms of euphorbia hirsuta, vinegar euphorbia hirsuta and preparations of euphorbia hirsuta, vinegar euphorbia hirsuta and preparations of euphorbia hirsuta and vinegar euphorbia hirsuta. The to-be-detected product raw material is a radix knoxiae raw material or a radix knoxiae raw material processed with vinegar; and S2) determining the to-be-detected liquid by adopting a high performance liquid chromatography to obtain the HPLC characteristic spectrum of the to-be-detected product. The method for detecting the characteristic chromatograms of the radix knoxiae, the vinegar radix knoxiae and the preparations of the radix knoxiae and the vinegar radix knoxiae can be used for quality detection of radix knoxiae medicinal materials-decoction pieces-standard decoction-formula granules or vinegar radix knoxiae decoction pieces-standard decoction-formula granules, the result is reliable, and a new method is provided for quality control of the radix
