ABSTRACT
Objective To establish the quality standard for Huamoyan Tablet. Methods Radix Salviae MiltioiThizae and Radix Cyathulaewere were identified by TLC. The content of protocatechuic aldehyde was determined by HPLC. Results The spots on TLC plates were clear without the interference of negative control. Protocatechuic aldehyde showed a good linear relationship in the range of 0. 021～0. 105 μg, r=0. 999 9. The average recovery was 98. 13 % ,and RSD=2. 41%. Conclusion The method is simple, sensitive and accurate, and can be used to control the qual-ity of Huamoyan Tablet.
ABSTRACT
AIM: To establish the quality standard for Huangqi Fufang Granules(Radix Astragali, Fructus Schisandrae Chinensis, Radix Cyathulae, etc.). METHODS: Fructus Schisandrae Chinensis, Radix Cyathulae were identified by TLC, and the content of astragaloside Ⅳ was determined by TLC scanning. RESULTS: Fructus Schisandrae Chinensis, Radix Cyathulae could be identified by TLC. Astragaloside Ⅳ showed a good linear relationship at a range of 1.0?g～6.0?g, r =0.9992. The average recovery was 99.19%, and RSD was 0.63%. CONCLUSION: The methods are simple, accurate and specific, and can be used for the quality control of Huangqi Fufang Granules.
