Abstract:ObjectiveTo establish the quality standards of Paishiyihao Granule.MethodsThe identification of Herba Desmodii Styracifolii, Rhzoma Alismatis were carried out by TLC. The content of chlorogenic acid was determined by HPLC. ResultsHerba Desmodii Styracifolii, Rhzoma Alismatis could be detected by TLC. A good linearity of chlorogenic acid was in the range of 0.010 32~0.103 20 mg/ml (r=0.999 8) and the average recovery of Chlorogenic acid was 99.95% ,RSD was 1.50% (n=5).ConclusionThis method is simple,sensitive, accurate and with good reproducibility and can be used for the quality control of Paishiyihao Granule.
