Abstract

OBJECTIVE:To establish the quality standard of Baoshenling capsules.METHODS:Radix Astragali,Radix et Rhizoma Rhei,Ligusticum chuanxiong and Hirudo were identified qualitatively by TLC,and the content of diphenyl ethylene in Baoshenling capsules was determined by HPLC.RESULTS:The characteristic TLC spots of Radix Astragali,Radix et Rhizoma Rhei,Ligusticum chuanxiong and Hirudo were identified accurately.The linear range of diphenyl ethylene was 0.176～0.880μg(r = 0.999 8) with an average recovery rate of 98.9%(RSD = 1.3%,n =6).CONCLUSION:The established standard is applicable for the quality control of Baoshenling capsules.
