The objective was to establish a quality standard of Compound Jinqiancao Granules for scientific evaluation and effective control of its quality, and to provide a reliable basis for the quality control.The herbs in the formula, such as Desmodii Styracifolii Herba and Pyrrosiae Folium were identified by TLC.Contents of mangiferin were determined by HPLC method.The method was established to distinguish Desmodii Styracifolii Herba and Pyrrosiae Folium.The spots in the TLC chromatograms were clear, and there were no interference from neg. control.Mangiferin had a good linearity in the range of 0.060 5-0.605 0 μg (r=0.999 5).The average recovery was 99.52%, and the RSD value was 2.13%.The method is simple and accurate, and has a good reproducibility, which can be used for the quality control of Compound Jinqiancao Granules.
