[High pressure liquid chromatographic determination of baicalin in lung-cleaning and diarrhoea-relieving infusion].
The baicalin in the compound recipe of traditional Chinese medicine Lung-cleaning and Diarrhoea-relieving Infusion was determined by reverse phase high pressure liquid chromatographic method. Methanol-water-tetrahydrofuran (200: 300: 50) was used as the mobile phase at ODS C-18 column with ultraviolet detection. The result showed that baicalin was separated well from other components. External standard method was used for quantitative determination. The recovery rate was 101.4% and RSD 0.83%.
