Objective:To establish the quality standard for Qianbai Biyan Tablets for better product quality control.Methods: Climbing groundsel
Semen cassiae
Herba ephedrae were identified by TLC.The content of chrysophanol was determined by HPLC.Results: Climbing groundsel
Semen cassiae
Herba ephedrae were identified by TLC
the spots were clear without interference.The content of chrysophanol was detected by HPLC
with good linearity between 0.054~0.54 μg.The average recovery of chrysophanol was 97.54%
and RSD was 1.57%
respectively.Conclusion:The method developed is accurate and the reproducibility is good.The method can be used to control the quality of Qianbai Biyan Tablets.
