Abstract:
OBJECTIVE:To establish an HPLC method for quantitative determination of baicalin in Yanyan capsules. METHODS:The determination was performed on Kromasil C18(250 mm?4.6 mm,5 ?m) with mobile phase consisted of meth-anol-water-phosphoric acid(47∶53∶0.2).The detection wavelength was set at 280 nm. RESULTS:The linear range of baicalin was 0.125～1.216 ?g(r=0.999 6) and its average recovery was 99.15%(RSD=0.62%,n=6).CONCLUSION:The method is simple and accurate,and it can be used for the quality control of Yanyan capsule.
