The determination was performed using Bavachin standard as control substance,and sodium hydroxide as color-developing agent,with the wavelength set at 440nm.RESULTS:
The absorbency and concentration of Bavachin have good linearity in the range of 4.10~ 12.30? g? mL-1(r=0.999 8).The average recovery rate was 100.5%(RSD=1.57%,n=9).CONCLUSION:
The method is easy to operate,highly accurate,reproducible and can be applied to determine the content of total Flavonoid in Fufang Psoralen corylifolia sustained-release tablets.
