摘要:

目的:利用微乳液相色谱分离并测定蓝莓叶中儿茶素、芦丁、山柰酚、槲皮素和杨梅酮5 种黄酮成分。方法:从表面活性剂、助表面活性剂、pH值、有机相4 个方面对微乳液相色谱分离蓝莓叶黄酮的条件进行优化。结果:分离蓝莓叶黄酮的最优条件为:使用2.5%聚氧乙烯(23)月桂醚作为表面活性剂,8%正丁醇为助表面活性剂,0.8%乙酸乙酯为有机相,0.5%乙酸调节体系pH值为3.2,在以上条件下蓝莓叶黄酮在20 min内能够得到有效分离。结论:蓝莓叶中提取的黄酮类化合物含有儿茶素9.76 mg/g、芦丁13.12 mg/g、山柰酚31.04 mg/g、槲皮素26.42 mg/g、杨梅酮20.30 mg/g。

Abstract:

Purpose: To optimize the procedure for isolating flavonoids from blueberry leaves by microemulsion liquid
chromatography (MELC) and to quantify the flavonoids obtained under the optimum conditions. Methods: Four MELC
conditions including surfactant, cosurfactant, pH of the mobile phase and organic phase were optimized. Results: The
optimum chromatographic conditions were determined as follows: 2.5% Brij-35 act as the surfactant, 8% 1-butanol as the
cosurfactant, the mobile phase adjusted to pH 3.2 with 0.5% acetic acid, and 0.8% ethyl acetate as the organic solvent.
The flavonoids in blueberry leaves could be separated efficiently and quantified precisely in 20 minutes under the above
conditions. Conclusions: The flavonoids in blueberry leaves included catechinic acid (9.76 mg/g), rutin (13.12 mg/g),
kaempferol (31.04 mg/g), quercetin (26.42 mg/g), and myricetin (20.30 mg/g).

Key words: blueberry leaves, flavonoids, microemulsion liquid chromatography, isolation, quantification
