Abstract:
OBJECTIVE:To establish a method for the simultaneous determination of chlorogenic acid,vitexin glucoside,vi-texin rhamnoside,vitexin,rutin and hyperoside in Crataegus pinnatifida. METHODS:With reference peak of vitexin glucoside, HPLC was conducted to calculate the relative correction factor(RCF)of chlorogenic acid,vitexin glucoside,vitexin rhamnoside, vitexin,rutin and hyperoside,then the contents of above-mentioned 5 components in C. pinnatifida were calculated. The column was Agilent ZORBAX SB C18 with mobile phase of 0.1% formic acid-acetonitrile-tetrahydrofuran (gradient elution) at a flow rate of 1.0 ml/min,the detection wavelength was 350 nm,column temperature was 30 ℃,and the injection volume was 10 μl. RE-SULTS:The linear range was 12.50-400.0 μg for chlorogenic acid(r=0.999 8),25.00-800.0 μg for vitexin glucoside(r=0.999 9), 31.25-1 000.0 μg for vitexin rhamnoside(r=0.999 9),6.470-260.0 μg for vitexin(r=0.999 9),2.50-80.0 μg for rutin(r=0.999 8) and 9.375-300.0 μg for hyperoside(r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2.0%;re-coveries were 99.2%-103.9%(RSD=1.6%,n=6),97.9%-100.8%(RSD=1.2%,n=6),99.2%-100.8%(RSD=0.5%,n=6), 97.3%-101.3%(RSD=1.5%,n=6),98.0%-103.0%(RSD=1.9%,n=6)and 95.5%-101.5%(RSD=2.2%,n=6). RCFs of vitex-in glucoside with chlorogenic acid,vitexin rhamnoside,vitexin,rutin and hyperoside were 1.119,1.009,0.706,1.063 and 0.830, respectively. CONCLUSIONS:The method is simple with good precision,stability and reproducibility,and it can be sued for the simultaneous determination of 6 components in C. pinnatifida.
