摘要: 建立蜂蜜中芦丁、杨梅酮、槲皮素、莰菲醇4种黄酮化合物含量的固相萃取-高效液相色谱检测方法。蜂蜜样品用pH2的盐酸溶液溶解、离心后,用Oasis HLB固相萃取柱吸附与净化,4种黄酮经VP-ODS色谱柱(150mm×4.6mm,5μm)分离,紫外检测器检测,检测波长270nm。流动相为甲醇-水(pH3.0)(60:40,V/V),流速0.7mL/min。检出限:芦丁、杨梅酮均为0.05mg/kg,槲皮素、莰菲醇均为0.04mg/kg;回收率:芦丁91%~92%、杨梅酮82%~85%、槲皮素84%~86%、莰菲醇86%~89%。分析云南省的5种特色蜂蜜样品,结果表明不同品种蜂蜜中4种黄酮类化合物含量差异显著,显示蜂蜜黄酮类化合物含量可作为鉴别蜂蜜品种的一个指标。

Abstract: A method for the determination of flavonoids in honey by SPE/HPLC was developed. The sample was extracted with acidified water (pH 2) and centrifuged, then enriched and cleaned-up by oasis HLB. The chromatographic separation was conducted on a VP-ODS (150 mm × 4.6 mm, 5 μm) column at the detection wavelength of 270 nm. The elution was completed by the mobile phase composed of methanol and water (pH 3) at the ratio of 60:40 (V/V) at the flow rate of 0.7 mL/min. The detection limits were 0.05 mg/kg for rutin and myricetin, and 0.04 mg/kg for quercetin and kaempferol, respectively. The recovery rates of rutin, myricetin, quercetin and kaempferol were 91%–92%, 82%–85%, 84%–86% and 86%–89%, respectively. Five kinds of characteristic honey from Yunnan were detected to reveal a significant difference in flavonoids. Therefore, flavonoids may be as the markers for the identification of honey.

Key words: flavonoids, characteristic honey, high performance liquid chromatography (HPLC)
