Abstract
OBJECTIVE To establish a method for the determination of baicalin in Jiangan mixture. METHODS The content of baicalin was determined by dual-wavelength TLC-Scanning method with 275nm and 365nm as the detection and reference wavelength respectively and with the upper of EtOAc: Butatone: MeOH: H2O (5:3:1:1) as developer. RESULTS: The linear range of baicalin was 0.80～2.40ug,The average recovery was 97.74%(RSD=1.23%,n=5) with linear ralationship(r=0.9990). CONCLUSIONS The method is simple and accurate,which could be used for the quality control of Jiangan mixture.
