Study on Quality Control of Chaibaiansheng Mixture

OBJECTIVE To establish the quality standards for quality control of Chaibaiansheng mixture. METHODS TLC was adopted to identify Radix Bupleurum, Bulbus Lily, Radix Paeoniae Alba, Fructus Schisandrae Chinensis and Rhizoma Chuanxiong, and a HPLC method was used to test the content of Baicalin. RESULTS TLC can identify these extraction: Radix Bupleuri, Bulbus Lilii, Radix Paeoniae Alba, Fructus Schisandrae Chinensis and Rhizoma Chuanxiong, and the Rf is reasonable and repeatable; Baicalin has good linearity relationship by HPLC in 0.103 2-1.032 μg(r=0.999 8), the average recovery is 99.7%, RSD is 1.5%(n=6). CONCLUSION This method of qualitative control is precise, easy and exclusive, and has good effect on quality control of Chaibaiansheng mixture.
