Objective: To establish the qualitative and quantitative methods for Puyi Granules. Method: Radix Polygoni Eultiflori
Herba Taraxaci
Semen Coicis and Ganoderma were identified by TLC
and the content of emodin in the preparation was determined by HPLC. Result: Radix Polygoni Eultiflori
Herba Taraxaci
Semen Coicis and Ganoderma could be identified well by TLC. The regression curve of emodin showed a good linear relationship in the range of 0.073~1.171 μg. The average recovery was 99.0%
RSD was 2.2%. Conclusion: The method is accurate
simple and has good repeatability. It can be used for quality control of Puyi Granules.
