Abstract

Objective To establish the quality standard of Dahuangtongqi Oral Liquid.Methods Rhei Radix et Rhizoma,Cannabis Semen,Chuanxiong Rhizoma,Aucklandiae Radix and Paeoniae Radix Rubra in Dahuangtongqi Oral Liquid were identified by TLC,and content of rhein,emodin and chrysophanol were determined by HPLC.Results The method for identification had good specificity and repeatability.There was no interference in blank control.The rhein,emodin and chrysophanol had good linearity in the range of 0.042-0.504 ?g(r=0.999 9),0.039-0.468 ?g(r=0.999 7),0.042-0.504 ?g(r=0.999 9) respectively.The average recovery of rhein,emodin and chrysophanol was 97.68%,97.36%,97.27%,and RSD was 1.09%,0.59%,0.97%(n=6),respectively.Conclusion The qualitative and quantitative method is simple,specific,accurate and reliable.It can be used to effectively control the quality of Dahuangtongqi Oral Liquid.
