摘要: 使用毛细管电泳法(CE)检测蜂胶中11种黄酮类化合物:金合欢素、芹菜配基、兰肉桂酸、黄良姜精、阿魏酸、橙皮甙、毛地黄黄酮、柑桔黄素、槲皮素、白藜芦醇、芦丁。确定了一些试验参数的优化条件,如:pH、缓冲溶液浓度、分离电压、进样时间以及UV检测器波长等。用H3BO3-Na2B4O7缓冲溶液(40mmol/L,pH8.85)在206nm波长条件下,各分析物可在19min内测出。相对标准偏差(RSD):8次进样的迁移时间为0.1%~0.3%;峰面积为3.0%~9.7%;各检测限(S/N=10)范围为0.1~0.4μg/ml;回收率为84%~110%。方法简单、灵敏,重现性好,用于蜂胶黄酮类化合物分析结果准确。

Abstract:  A rapid capillary electrophoresis(CE)method has been developed for the determination of eleven bioactive flavonoids in bee propolis:acacetin,apigenin,cinnamic acid,galangin,ferulic acid,hesperidin,luteolin,naringenin,quercetin,resveratrol,and rutin.Optimal conditions were optimized for several parameters,such as pH and concentration of buffer solution,separation voltage,electrokinetic injection time,and UV detection wavelength.Using a H3BO3-Na2B4O7 buffer(40mmol/L,pH8.85),the analytes were separated within 19min and detected at 206nm.The relative standard deviations of migration times in eight injections were between 0.1% and 0.3%,and those of the peak areas ranged from 3.0% to 9.7%.Excellent linearity was observed over two orders of magnitude,with quantitation limits(S/N=10)ranging from 0.1μg/ml to 0.4μg/ml for all the eleven analytes.Recoveries ranged from 84% to 110%.The new method is simple,reproducible and sensitive.Analysis results are accurate in health food applications.
