摘要 为了建立高效液相色谱法测定叶黄素顺、反异构体的方法,通过比较C18和C30色谱柱对叶黄素异构化样品的分离效果,并采用高效液相色谱-二级管阵列检测器-大气压化学电离-质谱对叶黄素顺、反异构体进行定性定量分析。该方法C30色谱柱为固定相,以甲醇-水(98:2,V/V)为流动相,在40~200ng范围内峰面积和进样量呈良好的线性关系,且具有较高的准确度和良好的重现性。该方法经济可靠,可用于叶黄素顺、反异构体的检测。 An HPLC-DAD-atmospheric pressure chemical ionization(APCI)-MS method was proposed to quantify and qualify lutein stereoisomers.A C30 column was found to be more effective in separating lutein stereoisomers than a C18 column.The mobile phase was composed of methanol and deionized water(98:2,V/V).A good relationship between peak area and injection amount was found in the range of 40 to 200 ng.The proposed method was accurate,reproducible,economical and suitable for the determination of lutein stereoisomers.
