HPLC法与UPLC法同时测定黄芩中5种黄酮类成分含量的比较
Comparison of HPLC and UPLC for the Determination of 5 Flavonoids in Scutellaria baicalensis
摘要
Abstract
OBJECTIVE:To provide simple and efficient method for the quality control of multiple componets in Scutellaria baicalensis.METHODS:HPLC and UPLC method were established to determine the contents of baicalin,wogonoside,baicalein,wogonin and oroxylin A in S.baicalensis.The separation,linear relationship,precision,reproducibility,stability and recovery were compared between 2 methods.For HPLC system,Diamonsil C18 (250 mm × 4.6 mm,5 μm) column was applied with mobile phase consisted of acetonitrile-water-formic acid (gradient elution) at the flow rate of 1.0 ml/min.The colunn temperature was 30 ℃,and detection wavelength was set at 280 nm.For UPLC system,Acquity BEH C18(50 mm×2.1 mm,1.7 μm) column was applied with mobile phase consisted of 0.1% formic acid-acetonitrile (gradient elution) at the flow rate of 0.4 ml/min.The column temperature was set at 40 ℃,and detection wavelength was set 280 nm.RESULTS:Both methods had good linear relationship in sample size and peak area (r≥0.999 5) ; RSDs of precision,stability and reproducibility tests were lower than 4% ; average recovery was higher than 96% (RSD<5%,n=6).CONCLUSIONS:Compared with HPLC method,UPLC method is faster and more sensitive and costs less solvents,and can be used for the quality control of various components in S.baicalensis simultaneously.关键词
