Objective: To establish the quality standard of the Tongfenglixiao preparations. Method: Qualitative identification was performed by thin layer chromatography on Dioscorea collettii
Papaya
Shichangpu
Aggregata
Smilax glabra;the content was measured with UV spectrophotometry the naringin in the formulations
with HPLC method for the content of chlorogenic acid in the it. Result: The naringin and chlorogenic acid showed good linear relationship (r=0.999 9
r=0.999 7) in the range of 0.056-0.196 mg
0.32-1.92 μg. The average recovery was 99.31%
99.66% with RSD 0.56%
0.415%. Conclusion: The method is simple
accurate and reliable
reproducible and can be used as agents of Tongfenglixiao quality control standards.
