The lipid composition of Semen ziziphi spinosae oil was analyzed based on lipidomics in this study,and the functional characteristics were further analyzed.There were 384 lipid components in 19 subclasses and 5 catego-ries from Semen ziziphi spinosae oil.Its lipid molecules were medium and long chain lipids with carbon chain lengths of 35～54,accounting for 66.60％,and unsaturated lipids accounted for 95.70％.Compared with the vegetable oil reported at present,there were 292 subtypes of glycerolipids(GL)in Semen ziziphi spinosae oil,being the most reported vegetable oil at present,and the content of diglycerides(DG)reached 1 090 607.62 mol/g.The prelimina-ry functional analysis indicated that the hypolipidemic activity of Semen ziziphi spinosae oil may be related to its large amount of DGs.
