反相高效液相色谱法同时测定植物油中8种维生素E异构体Simultaneous determination of eight vitamin E isomers in vegetable oils by RP-HPLC

为准确、快速地测定植物油中8种维生素E异构体，建立了均质快速提取法结合反相高效液相色谱法同时测定植物油中8种维生素E异构体的方法，并采用该方法对14种常见植物油进行测定。结果表明：与传统的皂化法和固相萃取法比较，均质快速提取法前处理快速简便，测定准确度和精密度高，重现性好；8种维生素E异构体在15 min内可以实现良好分离；在0.5~10 μg/mL质量浓度范围内8种维生素E异构体线性关系良好(R2＞0.999)，检出限为0.02~0.05 μg/mL，定量限为0.07~0.17 μg/mL，相对标准偏差在2.48%~5.79%之间，加标回收率在90.00%~110.00%之间；不同食用植物油...
