Summary

Three main and two minor components have been isolated from the total phospholipids of the seeds of kenaf of variety “Uzbeksii-1574” and have been characterized. The fatty-acid compositions of the total phospholipids, of the triglycerides, and of all the components of the phospholipids have been determined. Enzymatic hydrolysis of the main fractions of the phospholipids has been performed, the position distributions of the fatty acids have been determined, and, from this, the possible molecular compositions of the main components have been calculated.

The amide-bound fatty acids and those esterified in the glyceride part of the molecule of the N-acylphosphatidylethanolamines and their lyso analogs have been studied by mild alkaline deacylation. By means of acetolysis followed by lipolysis of the diglyceride acetates obtained with pancreatic lipase the position distributions of the fatty acids in the N-acyl-PE's have been elucidated and it has been shown that position 2 is esterified mainly with unsaturated acids, i.e., the same law is observed as in the main fractions of the phospholipids.
