    超高效液相色谱-三重四极杆串联质谱法同时 测定植物油中4种维生素E异构体Simultaneous determination of four vitamin E isomers in vegetable oil by ultra-high performance liquid chromatography- triple quadrupole tandem mass spectrometry by 李彩玲1,张见1,2,刘元法1,3,王晓超1,梅东旭1 LI Cailing1, ZHANG Jian1,2, LIU Yuanfa1,3, WANG Xiaochao1, MEI Dongxu1

    Published 2025-01-01
    “…To improve the detection efficiency of four vitamin E isomers (α-, β-, γ-, δ - tocopherol) in vegetable oil, a method for simultaneous determination of the content of four vitamin E isomers (α-, β-, γ-, δ - tocopherol) in vegetable oil by ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-MS/MS) was established. The conditions of mass spectrometry, chromatography, and sample pretreatment were optimized, and the method established was examined. …”
