摘要:

对薄壳山核桃仁油进行提取,利用制备型液相色谱-蒸发光散射-质谱联用技术分离和鉴定。分离得到7 个单体化合物,通过核磁与质谱数据比对,7 个单体化合物均为甘油三酯,分别为三亚油酸甘油酯、二亚油酸油酸甘油酯、棕榈酸二亚油酸甘油酯、亚油酸二油酸甘油酯、棕榈酸亚油酸油酸甘油酯、三油酸甘油酯、棕榈酸二油酸甘油酯。

Abstract:

Seven monomeric compounds from pecan (Carya illinoensis) oil were separated and identified by preparative
high performance liquid chromatography with evaporative light scattering detection combined with mass spectrometry
(HPLC-ELSD-MS). All these compounds were confirmed as triglycerides by comparison of their NMR and MS data with
those of authentic standards or literature data, namely trilinolein, dilinolein, 1,2-dilinoleoyl-3-palmitoyl-rac-glycerol,
dioleoylglycerol, 1-palmitin-2-olein-3-linolein, glycerol trioleate, dioleoyl 2-palmitoyl triglyceride, respectively.

Key words: Carya illinoensis oil, separation and identification, triacylglycerols
