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 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.

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 the ripening seeds ofSophora japonica

The change in the class and fatty acid compositions of the phospholipids during ripening of the seeds of the Japanese Pagoda tree (buds, flowers, unripe and ripe seeds) have been studied. It has been found that the ripening of the seeds is accompanied by complex transformations in the phospholipid complex indicating the important role of phospholipids in the processes of biosynthesis.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Phospholipids of the seeds of two species of Erysimum

Summary The phospholipid complexes of the seeds ofErysimum diffusum andE. sylvestris have been investigated. It has been found that the amount of phospholipids in the seeds ofE. diffusum is lower than in those ofE. sylvestris, but their qualitative compositions are similar. The fatty-acid compositions of the triglycerides and of the total phospholipids of the two plants investigated have been studied. It has been established that the total phospholipids of the species ofErysimum under consideration and individual fractions of them differ by the degree of saturation and the qualitative and quantitative composition of the acids that they contain and, consequently, the phospholipids present in greatest amount differ in their molecular compositions.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Phospholipids of the seeds of experimental varieties of kenaf

Phospholipids of the seeds of kenaf of the variety Opytnyi-1931 are similar with respect to their set of components and the qualitative composition of the fatty acids of homogeneous classes to the phospholipids of the variety Opytnyi-1972, but differ with respect to the amounts of individual acids. The fatty-acid composition of the lysophosphatidylcholines and lysophosphatidylinositols of experimental varieties of kenaf seeds have been studied for the first time.Institute of the Chemistry of Plant Substances of the Academy of Sciences of the Uzbekh SSR, Tashkent.

Neutral lipids of the seeds ofPhlomis oreophilla andPh. regelii

The lipid and fatty acid compositions of the seeds ofPhlomis oreophilla andPh. regelii (familyLabiatae) have been studied. The lipids ofPh. oreophilla are enriched with linoleic acid and those ofPh. regelii with oleic acid. Laballenic acid is present in the total acids of the triacylglycerides and the free fatty acids of both species, being concentrated in the free acids. The epoxy acids ofPh. oreophilla are represented by 9,11-epoxystearic, vernolic, coronaric, and 15,16-epoxylinoleic acids.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Tomatoside a from the seeds ofLycopersicum esculentum

Results are given which confirm the structure of the furostanol glycoside from tomato seeds forming wastes of the preserving industry. From a butanolic extract of the seeds ofLycopersicum esculentum Mill. we have isolated the furostanol glycoside tomatoside A (I) the structure of which has been established as 25(S)-5-furostan-3,22,26-triol 26-O--D-glucopyranoside 3-O-[O--D-glucopyranosyl-(12)-O--D-glucopyranosyl-(14)--D-galactopyranoside]. At the same time, by enzymatic and chemical transformations three new spirostanol glycosides of neotigogenin have been obtained: tomatoside B (III), which is 25(S)-5-spirostan-3-ol 3-O-[O--D-glucopyranosyl-(12)--D-galactopyranoside], 25(S)-5-spirostan-3-ol 3-O-[O--D-glucopyranosyl-(14)--D-galactopyranoside] (V), and 25(S)-5-spirostan-3-ol 3-O--D-galactopyranoside (IV).Institute of Organic Chemistry, Academy of Sciences of the Kirghiz SSR, Frunze.
