ABSTRACT

Objective To study the qualitative and quantitative standard of Shengui anti-pruritic mixture. Mehtods Sophorae Flavescentis Radix, Cnidii Fructus, Polygoni Multiflori Radix, Astragali Radix, Paeoniae Radix Alba and Glycyrrhizae Radix Et Rhizoma were identified by TLC.The contents of matrine and ferulic acid were determined by HPLC. Results The TLC showed the obvious characteristics with the spots clear and well-separated with no interference by negative control. Matrine showed a good linear relationship at 0.062 5- 2.500 0 μg (r=0.999 9) with a good meeting of adding sample recovery test. Ferulic acid showed a good linear relationship at 0.021 0-0.840 0 μg (r=0.999 9) with a good meeting of adding sample recovery test. Conclusions The method is easy-operated and accurate which showed a good specificity for the quality control of Shengui anti-pruritic mixture.
