OBJECTIVE： To establish the quality standard for Qindan granules. METHODS： The constituents including Radix Seutellariae, Radix Astragali, Cortex Moutan and Fruetus Gardeniae in Qindan granules were identified respectively by TLC. RESULTS： The test samples and their respective reference substances were alike in that the same color chromatographic spots were noted at the corresponding places. The color spectra of the samples were clear yet without interference of surrounding impurity. CONCLUSION： The established method has high specificity and can be used for the quality control of Qindan granule.
