Phospholipids of seeds of kenaf of the variety "Uzbekskii-1503"

Summary The qualitative and quantitative compositions of the combined phospholipids of the seeds of kenaf of the variety "Uzbekskii-1503" have been determined for the first time.The fatty-acid composition of the combined phospholipids and triglycerides and also of the main and two minor components of the phospholipids have been studied. On the basis of the results of acid hydrolysis and of IR spectroscopy, the glycerophospholipid structures of the main and minor components of the total material have been confirmed. The enzymatic hydrolysis of the main fractions of the total material has been performed: the position distribution of the fatty acids has been determined and from this the possible molecular compositions of the phosphatidylcholines, phosphatidy lethanolamines, and phosphatidy linositols have been calculated. Kenaf seeds can serve as a source of the medicinal preparation phytin.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Phospholipids of kenaf during its growth

The change in the fractional and fatty-acid compositions of the total phospholipids in various organs of kenaf during its growth has been studied. It has been found that phospholipids are synthesized in all stages of the development of kenaf, but most intensively during its ripening.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Phospholipids of kenaf of variety Opytnyi-1847

The total phospholipids of kenaf of variety Opytnyi-1847 and homogeneous fractions of them have been studied. A known law has been confirmed — positions 2 of the main fractions of phospholipids are esterified predominantly with unsaturated fatty acids and in N-aceylated phospholipids the amide-bound acids are more saturated than the O-acyls.Institute of the Chemistry of Plant Substances of the Academy of Sciences of the Uzbek SSR, Tashkent.

Phospholipids ofGoebelia seeds

The qualitative and quantitative compositions of the phospholipids of the seeds ofGoebelia pachycarpa and the fatty-acid composition of the total phospholipids and of homogeneous fractions have been studied. The molecular weights of the main fractions have been calculated.     

Phospholipids of the seeds ofPhaseolus vulgaris

Six homogeneous fractions have been isolated from the total phospholipids of the seeds of the kidney bean, and their ratios and fatty acid compositions and the position distributions of the fatty acid radicals in the main fractions have been determined.     

Phospholipids of the seeds ofFumaria vaillantii

The qualitative and quantitative compositions of the phospholipids from the seeds ofFumaria vaillantii L. have been determined. The total fatty acid compositions of all the classes of phospholipids and the position-distributions of the phosphatidylcholines, phosphatidylinositols, and phosphatidylethanolamines have been investigated.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 40 64 75.

Phospholipids of ripeSophora japonica seeds

Nine classes of lipids have been isolated in homogenous form from ripe seeds of the Japanese pagoda tree, and their fatty acid compositions have been established. The positional distributions of the fatty acids in the phosphatidylcholines, phosphatidylethanolamines, and phosphatidylinositols have been determined.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 40 64 75.
