Tri acyl glycerol composition of seeds of certain representatives of the labiatae family


Khimiya Prirodnykh Soedinenii (5): 618-625
Tri acyl glycerol composition of seeds of certain representatives of the labiatae family
The position-specific structure of triacylglycerols (TAG) of 22 wild-growing species of Labiatae was studied for the 1st time as well as the fatty-acid composition of 5 of the 22 spp. (Eremostachys hissarica, Lavandula vera, Marrubium alternidens, Monarda rosea, Phlomis salicifolia). .omega.-12,13-Octadecadienoic acid was detected in those 5 species. The TAG type structure differed from that of known plant oils with a similar set of fatty acids by the presence of S2U (S = saturated, U = unsaturated) (0.1 - 1.6%) and the absence of type S3 TAG. The principal types were SU2 (5-24%) and U3 (74-95%). In comparing the position-specific structure of the oils studied it was established that plant oils of this family are distinguished by great variability of TAG types as well as by the kind of distribution encountered for acyls of unsaturated acids between 1,3- and 2-positions. In the majority of oils studied, 18:1 acid was found in the 2-position, 18:2 acid was distributed primarily in the 1,3-positions, while 18:3 acid, when it occurred, was found in all 3 positions.
