TITLE:
摘要: 目的:建立同时测定山楂叶中绿原酸、牡荆素葡萄糖苷、牡荆素鼠李糖苷、牡荆素、芦丁、金丝桃苷含量的方法。方法:采用高效液相色谱法,以牡荆素葡萄糖苷为基准峰,分别计算其与绿原酸、牡荆素鼠李糖苷、牡荆素、芦丁、金丝桃苷的相对校正因子(RCF),通过RCF计算山楂叶中上述5种成分的含量。色谱柱为Agilent ZORBAX SB C18,流动相为0.1%甲酸-乙腈-四氢呋喃(梯度洗脱),流速为1.0 ml/min,检测波长为350 nm,柱温为30 ℃,进样量为10 μl。结果:绿原酸、牡荆素葡萄糖苷、牡荆素鼠李糖苷、牡荆素、芦丁、金丝桃苷检测进样量线性范围分别为12.50~400.0 μg(r=0.999 8)、25.00~800.0 μg(r=0.999 9)、31.25~1 000.0 μg(r=0.999 9)、6.470~260.0 μg(r=0.999 9)、2.50~80.0 μg(r=0.999 8)、9.375~300.0 μg(r=0.999 9);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为99.2%~103.9%(RSD=1.6%)、97.9%~100.8%(RSD=1.2%)、99.2%~100.8%(RSD=0.5%)、97.3%~101.3%(RSD=1.5%)、98.0%~103.0%(RSD=1.9%)、95.5%~101.5%(RSD=2.2%),n均为6。牡荆素葡萄糖苷与绿原酸、牡荆素鼠李糖苷、牡荆素、芦丁、金丝桃苷间的RCF分别为1.119、1.009、0.706、1.063、0.830。结论:该方法操作简便,精密度、稳定性、重复性好,可用于6种有效成分含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of chlorogenic acid, vitexin glucoside, vitexin 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. RESULTS: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%; recoveries 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 vitexin 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.
