Objective:To improve the quality standard of Wanbiqing Pill. Method: The TLC method was used to identify Arnebiae Radix
Euodiae Fructus and Smilacis Glabrae Rhizoma. The HPLC method was used to detect the content of loganin in Lonicerae japonicae caulis. Result: This TLC method is good in separation
strong in specificity and negative in interference. Loganin was detected in the range of 0.013 4-0.080 4 g·L-1
indicating good linear relationship (r=0.999 8). The mean sample recovery rate was 97.07% and the RSD was 1.24%. Conclusion: The TLC and HPLC methods are simple and accurate in operation
high precision and good in reproducibility
and they can be taken as the standard of quality control for Wanbiqing Pill.
