Lipids of the seeds ofPaliurus spina-christi

The composition of the unsaturated and oxidized fatty acids and steroids of the lipids of the seeds ofPaliurus spina-christi has been determined. Among the unsaturated acids the 20:1 (11) was detected, while the 18:1 and 18:2 acids predominate. The oxidized acids are represented by the sum of the 9,10(12,13)-epoxy-12(9)-18:1, the 9,10-epoxy-18:0, the oxo-18:1, the oxo-18:2, the 12-hydroxy-9-18:1, and the 9-hydroxy-10,11-18:2 acids. The main component of the sterols is -sitosterol. It has been found that the composition of the acylglycerols of the lipids of the seeds ofP. spina-christi gathered in different years is variable.I.

Lipids ofHeracleum lehmannianum seeds

The lipid complex of the seeds ofHeracleum lehmannianum B. has been studied. The qualitative and quantitative compositions of the neutral lipids and the phospho- and glycolipids, and the fatty acid compositions of the acyl-containing classes of lipids have been determined. It has been shown that the neutral and the polar lipids differ considerably from one another with respect to the level of certain fatty acids. The position-species compositions of the TAGS and of the main components of the phospholipids have been calculated from the results of lipolytic hydrolysis.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 89 14 75.

Lipids ofViburnum opulus seeds

Lipid components of the seeds ofViburnum opulus (Caprifoliaceae family) were investigated. The neutral lipids consist of eight classes, the glycolipids consist of three classes, and the phospholipids contain seven classes. The fatty-acid contents of all of the acyl-containing lipids were determined. The 18∶2 fatty acid is the main component of all the lipid fractions. The content of saturated acids is greater in the glycolipids and phospholipids. The lipophilic components, higher fatty alcohols and sterols, were identified.     

Lipids ofPhellodendron lavalei seeds

The chemical composition of neutral lipids and phospholipids from seeds ofPhellodendron lavalei cork is studied. Characteristic features of the fine structure of the separate classes are found. Significant quantities of eicosatrienoic acid and neutral lipids are found. The polar lipids are biologically active.Deceased.I. G.

Lipids of Hibiscus cannabinus seeds

The neutral and polar lipids of kenaf seeds of the variety Uzbetskii-1574 from the 1983 crop have been studied. The fatty acid compositions of six acyl-containing classes of neutral lipids have been established for the first time. The acids in the sn-2 positions of the triacylglycerols and of the main classes of phospholipids have been determined. The main triacylglycerol species are those in which the sn-2 position is esterified by linoleic acid.
