Abstract: Objective To establish the quality standard for Xiangsu Weitong capsule. Methods Radixet rhizoma glycyrrhizae,rhizoma corydalis,poria,rhizoma cyperi were identified by TLC and the contents of baicalin were determined by RP-HPLC. Chromatography conditions were Welchrom C18 (4.6 mm×250 mm, 5 μm) column. The mobile phase was acetonitrile-0.1% phosphoric acid(40:60). UV detection wavelength was set at 280 nm and the column temperature was 30℃ with the flow rate of 1.0 ml/min. Results The method of TLC had good resolution with clear spots and negative control showed no interference. The good linearity was obtained within the range of 1-80 μg/ml(r=0.999 9) for Tetrahydropalmatine hydrochloride and the average recovery was 99.1% (RSD=1.28%,n=6). Conclusion The method was simple, accurate and sensitive which could be applied in the quality control of Xiangsu Weitong capsule.
