摘　　要：建立气相色谱-质谱联用仪内标法测定大豆渣油中维生素E的方法。以Agilent-5MS 5%Phenyl MethylSiloxane(30 m×0.25 mm×0.25μm)毛细管气相色谱柱为分析柱,柱温230℃,进样口230℃,检测器230℃,内标法计算维生素E的含量。维生素E线性范围是0.1～2 mg/mL,回收率为95.95%,RSD为3.52%。该方法快速、简便,是测定大豆渣油中维生素E含量的一种较好的方法。A method for determining vitamin E in soybean residue with GC-MS was established by using internal standard method.The chromatography column was Agilent-5MS 5% Phenyl Methyl Siloxane（30 m×0.25 mm×0.25 μm） quartz capillary column.Column temperature was 230 ℃,the temperature of MS detector was 230 ℃,the temperature of injection was 250 ℃.The line range of the determination vitamin E was 0.1～2 mg/mL,the recovery was 95.95% and RSD was 3.52%.The method has been proved to be reliable and accurate.
