A group of unusual triglycerides, in which one of the acyl groups is a vicinal dihydroxy acid with one of the hydroxyl groups acetylated, has been isolated from Cardamine impatiens L. (Cruciferae) seed oil. Hydrolysis of these triglycerides with castor bean lipase facilitated isolation and identification of a mixture of C 18 , C 20 , C 22 , and C 24 hydroxy acetoxy fatty acids. Pancreatic lipase hydrolysis data revealed that these monoacetylated dihydroxy acid residues are esterified exclusively with one of the α‐positions of the glycerol moiety. The remaining acyl groups are comprised of ordinary C 18 unsaturated acids (which occupy 98% of the β‐position), palmitic acid, and C 20 , C 22 , and C 24 monoenoic fatty acids.
