The fractional composition of the polar lipids and also the fatty-acid composition of the main components of the phospholipids of the Chinese tallow tree have been studied. It has been established that in the seeds of the Chinese tallow tree there are 11 phospholipids, two glycolipids, and two phosphonolipids. The main fatty acids of the phospholipids are palmitic and linoleic.I. G. Kutateladze Institute of Pharmatochemistry, Georgian Academy of Sciences, Tbilisi.

The composition of the fatty acids and phospholipids of 16 species of lichens collected in the basin of the river Volga has
been studied. The main phospholipid was phosphatidylcholine the amount of which ranged in the various species from 33.3 to
85.5% of the total phospholipids. Other phospholipids were also found: phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol,
and phosphatidylglycerol. The main fatty acids were the 16:0, 18:0, and 18:1 varieties.

The class composition of the lipids of the biomass of the microalgaMonochrysis lutheri grown under the accumulation regime of cultivation has been investigated for the first time. A predominance of triacylglycerols
in the neutral lipids, of phosphatidylcholine in the phospholipids, and of digalactosyldiacylglycerols in the glycolipids
has been established. New natural alkan-8-ones of the C36-C50 series have been detected.

By chromatographic methods, about 30 groups of various lipid compounds belonging to the classes of neutral lipids, glycolipids, and phospholipids have been identified from the fruit of the fig tree. The main groups are triacylglycerols, free and esterified sterols, mono- and digalactosyldiglycerides, ceramide oligosides, cerebrosides, esterified sterol glycosides, and phosphatidylglycerols. In the fatty acid composition, linoleic, linolenic, oleic, and palmitic acids predominated (>90%).A. V. Bogatskii Physicochemical Institute, Academy of Sciences of the Ukrainian SSR, Odessa.

The electrohydraulic (EH) treatment of water-plant heterodisperse systems leads to the partial degradation of the main components
of the plant materials: lignin, cellulose, and carbohydrates. The presence of p-hydroxyphenyl and guaiacyl structures has
been established on the basis of the results of the GLC analysis of the ether-extracted phenolic products of plant materials
subjected to EH treatment. It has been shown that part of the carbohydrates passes into the aqueous phase in the form of free
monosaccharides: pentoses and hexoses.

which is used for treating impotence and female infertility, have been studied. It has been shown that together with trillin,
prosapogenin A of dioscin, trillarin, dioscin, gracillin, protodioscin, and protogracillin, tribestan contains a diosgenin

phospholipids were 3.1 and 1.7%, respectively. Among the fatty acids, in addition to the usual components, acids characteristic
for theBoraginaceae family have been found: 18:3 (6, 9, 12), 18:3 (9, 12, 15), 18:4 (6, 9, 12, 15), 20:1 (11), 22:1 (13), and 24:1 (15).

Summary The fatty-acid composition of the combined phospholipids 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 also IR spectroscopy, the glycerophospholipid structure of the main components of the total material has been confirmed. These main components have been subjected to enzymatic hydrolysis: the position distribution of the fatty acids have been determined and, from these, the possible diglyceride compositions of the phosphatidylcholines, phosphatidylethanolamines, and phosphatidylinositols have been calculated. It has been shown that the phospholipids are accompanied by 35–40% of carbohydrates which have been characterized qualitatively as disaccharides.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

The difference-perturbation absorption spectra of monoiodotyrosine, diiodotyrosine, triiodothyronine, and thyroxine with low-
and high-molecular-mass polyethyleneglycols as perturbants have been measured and characterized. The SDP spectra, and their
intensity and the position of the main maximum depend on the number of iodine atoms and the state of ionization of the hydroxyl
in accordance with their electron-accepting properties.

The lipid complex of the seeds ofPeganum harmala (fam. Zygophyllaceae) has been investigated. The qualitative and quantitative compositions of the neutral lipids and the
phospholipids have been studied. The fatty acid compositions of the acyl-containing lipids have been determined and it has
been shown that in the triacylglycerols and phosphatidylethanolamines the sn-2 position is esterified mainly by linoleic acid.

The spatial structure of the sesquiterpene humulane alcohol juniferol, which is represented in the crystal by two conformers,
IA and IB, differing by the conformation of the C2...C9 section, has been established by the x-ray structural method. The
strain energies of the conformers have been calculated by the method of molecular mechanics. The barrier to the interconversion
of the conformers by rotation of the C2...C9 section has been calculated; it amounts to 7–8 kcal/mole. This value of the transformation
barrier permits the assumption that the two conformers also exist in solution, their interconversion being hindered.
