中文摘要:建立了超高效液相色谱-串联质谱(UPLC-MS/MS)同时测定蜂蜜中24种酚酸和黄酮类化合物的方法。样品经水溶解,SHIMSEN Styra MAX固相萃取柱净化,超高效液相色谱-串联质谱测定,外标法定量。结果表明,24种化合物在2 ~ 1 000 μg/L范围内线性关系良好,相关系数(r2)均大于0.998,方法定量下限为2 ~ 10 μg/kg;在200、400、1 000 μg/kg加标水平下,平均回收率为60.3% ~ 111%,相对标准偏差为0.80% ~ 8.5%。采用该方法测定15批次5种植物源蜂蜜样品,结果显示样品中均含有不同浓度的没食子酸、短叶松素、高良姜素、松属素、原儿茶酸、对香豆酸、对羟基苯甲酸、咖啡酸、槲皮素、异鼠李素、莰菲醇和柯因等18种化合物,均不含有迷迭香酸和桑色素。该方法前处理简单、快速、灵敏、稳定,可用于蜂蜜中酚酸类和黄酮类物质的测定。

Determination of 24 Kinds of Phenolic Acids and Flavonoids in Honey by Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry
Abstract:An ultra-high performance liquid chromatography-tandem mass spectrometric method (UPLC-MS/MS) was established for the determination of 24 kinds of phenolic acids and flavonoids in honey.The target compounds were extracted with water,then purified and concentrated with a SHIMSEN Styra MAX solid phase extraction column,and finally analyzed by UPLC-MS/MS and quantified by external standard method.Under the optimal conditions,there were good linear relationships for 24 target compounds in the range of 2-1 000 μg/L with correlation coefficients(r2) greater than 0.998.The limits of quantitation for the analytes were in the range of 2-10 μg/kg.The average recoveries ranged from 60.3% to 111%,with relative standard deviations of 0.80%-8.5%.The established method was successfully applied to the rapid detection of 15 samples from five types of honey.It was found that 18 compounds including gallic acid,pinobanksin,galangin,pinocembrine,protocatechuic acid,p-coumaric acid,p-hydroxybenzoic acid,caffeic acid,quercetin,isorhamnetin,kaempferol and chrysin etc.were detected in all honeys,but there existed significant differences in their contents.Meanwhile,rosmarinic acid and morin were undetected in all honeys.The method is simple,rapid,sensitive and stable,and it could be used for the simultaneous determination of various phenolic acids and flavonoids in various honeys.
