Study on Quality Standard of Jin Gen Qin Lian Powder

The assay was aimed to establish the thin layer chromatography (TLC) quality standard for Jin Gen Qin Lian powder. In this experiment TLC was used for qualitative identification of Chinese medicinal herbs in the components,and ultimately determined the TLC for Flos Lonicerae, Radix Scutellariae, Fructus Forsythiae and Radix Bupleuri.Under this selected chromatographic conditions, good chromatographic spots were separated. This method could effectively identify Flos Lonicerae, Radix Scutellariae, Fructus Forsythiae and Radix Bupleuri in the compound. The method established in this experiment was simple and focused with good reproducibility, so it could be used to provide a reliable basis for control the quality of compound.
