Abstract:Objective: To establish an HPLC method for simultaneously determining the contents of calycosin-7-O-β-D-glucoside, hypericin, rutin, isoquercetin, myricetin, quercetin, loganin, morroniide in compound Huangkui granules. Method: The determination was performed on an Aglient C18(4.6 mm×250 mm,5 μm) chromatographic column,the mobile phase was acetonitrile-0.05% formic acid aqueous solution with gradient elution at a flow rate of 1.0 mL·min-1;the detection wavelength was 240,260 and 360 nm, column temperature was 30 ℃. Result: The calibration curves of calycosin-7-O-β-D-glucoside, hypericin, rutin, isoquercetin, myricetin, quercetin, loganin, morroniide were linear in the ranges of 3.5-35.0(r=0.999 6),32.09-300.9(r=0.999 7),2.21-22.12(r=0.999 7),18.68-186.9(r=0.999 8),6.32-63.20(r=0.999 7),3.54-35.44(r=0.999 6),12.39-123.9(r=0.999 6), 12.88-128.8 mg·L-1(r=0.999 6),respectively. The average recoveries were 98.1%(RSD 1.7%),99.7%(RSD 0.6%),98.7%(RSD 2.5%),100.1%(RSD 1.4%),99.7%(RSD 1.0%),99.9%(RSD 2.7%),99.0%(RSD 1.2%),99.7%(RSD 1.3%),respectively. Conclusion: The method established is simple, accurate and reproducible, which can be used for the quality control of Huangkui granules.
