Composition of the phospholipids of Gossypium barbadense

Summary 1. The combined phospholipids of the seed kernels of the cotton plant have been completely freed from accompanying carbohydrates by gel filtration on Molselekt G-25.2. It has been established by two-dimensional chromatography in a thin layer of silica gel that the phospholipids of the seed kernels of the cotton plant of thin-fibered variety 5904-I consist of X₁- and X₂-polygly cerophosphatides (2.4 and 7.1%, respectively), phosphatidylethanolamines (14.1%), phosphatidylcholines (50.4%), phosphatidylinositols (20.4%), and lysophosphatidylcholines (5.6%).3. The accompanying substances of the phospholipids of the cotton plant form two groups each of steroids and disaccharides.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSSR, Tashkent.

Composition of the phospholipids of the cotton plant Gossipium barbadense

Summary 1. The fatty-acid compositions of the oil, the total phospholipids, and the main groups of phospholipids of the seed kernels of the fine-fibered cotton plant of variety 5904-I have been determined. The complete qualitative identity of the acids present in them and quantitative similarity of the acids in the oil and in the total phospholipids have been shown: in the degree of increasing saturation the phospholipids form the following sequence: phosphatidylcholines, phosphatidylethanolamines, phosphatidylinositols.2. It has been established by enzymatic hydrolysis with phospholipase A₂ of kufi venom that the unsaturated fatty acids are present in position of the PCh, PE, and PI molecules — to the extent of 90.6%, 96.5%, and 85.4%, respectively.3. From the position distribution of the fatty acids in the phospholipids, their possible molecular compositions have been calculated.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Phospholipids of Gossypium barbadense

Summary From the total phospholipids of the cotton plant of the thin-fibered variety 5904-I(Gossypium barbadense) chromatographically homogeneous fractions of phosphatidylethanolamines, phosphatidylcholines, and phosphatidylinositols have been isolated. The well-known glycerophospholipid structure of these fractions has been established on the basis of their IR spectra and the products of their acid hydrolysis.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Flavonol glycosides of the flowers of a thin-leaved cotton plant of the species Gossypium barbadense

Summary The flowers of the thin-leaved cotton plant of variety 5904-I(Gossypium barbadense) contained more than 5% of combined flavonols consisting of quercimeritrin, hisutrin, quercetin 3-glucoside, and a flavonol with mp 228–229°C. The latter has the structure of gossypetin 7--D-glucopyranoside.Scientific-Research Institute for the Chemistry and Technology of Cotton Cellulose, Tashkent.

A study of the water-soluble proteins of the seeds of the cotton plants Gossypium hirsutum and G. barbadense

It has been shown by electrophoresis in polyacrylamide gel that different enzymes with similar electrophoretic mobilities may be localized in one and the same zone of water-soluble cottonseed proteins. Some zones not stained by the usual protein dyes also possess enzymatic activity. It has been established that the majority of the electrophoretic fractions consist of a series of polypeptides with different molecular weights, mainly of low-molecular-weight nature. The results are given of an investigation of the peroxidase, α-amylase, lipase, NADH-DCPIP oxidoreductase, and NADPH-DCPIP oxidoreductase activities of the water soluble fraction of the proteins of the seeds of the species mentioned.
