摘　　要：采用超高效合相色谱串联四级杆飞行时间质谱(UPC^2-Q-TOF-MS)技术分析了11种植物油的甘油三酯组成。这些植物油中,O-L-L为葵花籽油(22. 27%±1. 87%)、菜籽油(21. 07%±1. 76%)、玉米油(19. 84%±1. 35%)、米糠油(19. 37%±0. 87%)、芝麻油(17. 55%±0. 82%)中含量最高的甘油三酯; O-O-O在花生油(18. 25%±0. 69%)和橄榄油(39. 37%±0. 10%)中的含量最高;大豆油中含量最高的甘油三酯是L-L-L(22. 16%±1. 71%),亚麻籽油中是O-Ln-Ln(21. 85%±0. 18%),稻米油中是O-L-P (18. 58%±1. 02%),以及棕榈油中是O-P-P(25. 05%±0. 73%)。O-O-L与S-L-L等ECN值相同的甘油三酯实现了分离,且含量微少的甘油三酯组成也得到了鉴定。The compositions of triglycerides in eleven kinds of vegetable oils were analyzed by ultra performance convergence chromatography with quadrupole time -of- flight mass spectrometry （UPC2 -Q - TOF- MS）. Among these vegetable oils, O - L - L contents were the highest in sunflower seed oil （22.27% ± 1.87% ）, rapeseed oil （21.07% ± 1.76% ）, corn oil （ 19.84% ± 1.35% ）, rice bran oil （19.37% ±0.87% ） and sesame oil （17.55% ±0.82% ）, while O- O- O content was the highest in peanut oil （ 18.25% ± 0.69% ） and olive oil （ 39.37% ± 0.10% ）. The triglyceride with the highest content in soybean oil, linseed oil, rice oil and palm oil were L - L - L （22.16% ± 1.71% ）, O - Ln - Ln （ 21.85% ± 0.18% ）, O - L - P （ 18.58% ± 1.02% ） and O - P - P （25.05% ± 0.73% ）, respectively. Triglycerides with the same ECN value, such as O - O - L and S - L - L, were isolated. The contents of trace triglyceride were also identified.
