Lipids of the fruit ofAcanthopanax sessiliflorus

In the lipids of the seeds and pericarp of the introduced speciesAcanthopanax sessiliflorus (Rupr. et Maxim.) Seem (familyAraliaceae), 23 classes of compounds have been detected, of which 19 have been identified. Sixteen of the classes have been studied. The lipids of the pericarp contain a more complex set of components than the seeds. Hydroxyacyldiacylglycerides, fatty acid methyl esters, and a complex group of pthalicacidesters have been detected in the familyAraliaceae for the first time. The fatty acid compositions of the seed and pericarp lipids are characterized by a high level of petroselinic acid.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Investigation of the core of the lipopolysaccharides ofYersinia pseudotuberculosis

Lipopolysaccharides have been isolated from two R mutants of the pseudotuberculosis microbeYersinia tuberculosis, serovar VA. Mild acid hydrolysis followed by gel filtration on Sephadex G-25 gave the core oligosaccharides OS I and OS II. Complete acid hydrolysis showed that OS I consisted of residues of D-galactose, G-glucose, two heptoses (D-glycero-D-mannoheptose and L-glycero-D-mannoheptose), and D-glucosamine in a ratio of 1:2.5:4:1, while OS II consisted of residues of D-glucose, heptoses, and D-glucosamine in a ratio of 1:2.5:0.2. On the basis of the results of monosaccharide analysis, methylation, Smith degradation, etc., a partial structure of the core oligosaccharide of the LPS ofY. pseudotuberculosis has been put forward.Pacific Ocean Institute of Bioorganic Chemistry, Far Eastern Scientific Center, Academy of Sciences of the USSR, Vladivostok.

Lipids and lipopolysaccharides of the genusFlavobacterium

The fatty acid compositions of the free lipids of three strains and the monosaccharide compositions of the lipopolysaccharides of four strains of new species of microorganisms of the genusFlavobacterium have been studied. The acidic nature of the polysaccharides of the LPSs of the microorganisms studied has been shown.     

Spectrophotometric determination of the furocoumarins ofPsoralea drupaceae andFicus carica

Conclusions A spectrophotometric method for the separate quantitative determination of the furocoumarins ofPsoralea drupaceae Bge. andFicus carica L. has been developed.Khimiya Prirodnykh Soedinenii, Vol. 5, No. 6, pp. 473–476, 1969     

Flavonoids ofPhellodendron sachalinense andPh. amurense

Summary 1. About ten substances of a flavonoid nature have been found in the leaves ofPhellodendron sachalinense (F. Schm.) Sarg. andPh. amurense Rupr.2. The two species of cork tree each contain two new flavonoids, which have been called phelloside and dihydrophelloside. The results of chemical and spectroscopic studies have permitted phelloside to be characterized as the 7,-di-O--D-glucopyranoside of noricaritin and dihydrophelloside as the 7,-di-O--D-glucopyranoside of dihydronoricaritin, the base of which contains kaempferol and aromadendrin.3. Amurensin (the 7--D-glucopyranoside of noricaritin) and icariside-1 (the -O--D-glucopyranoside of noricaritin) have been isolated as intermediates in the stepwise hydrolysis of phelloside; the latter has not been previously found in the Amur and Japanese cork trees.Khimiya Prirodnykh Soedinenii, Vol. 4, No. 2, pp. 77–82, 1968     

Alkaloids ofCorydalis pseudoadunca andC. gortschakovii

Conclusions From two species ofCorydalis with different growth sites 11 bases were obtained.FromC. pseudoadunca, collected in the Alai Valley, d-bicuculline, d--hydrastine,l-adlumidine, l-scoulerine, coramine, and protopine were isolated; fromC. pseudoadunca, collected in the Pamir d--hydrastine, protopine, d-bicuculline, coramine, andl-scoulerine; and fromC. gortschakovii, collected in the western Tien-Shan, isocorydine, protopine, sendaverine, d-bicuculline,l-adlumine, and a base with mp 240–242° C.Khimiya Prirodnykh Soedinenii, Vol. 6, No. 4, pp. 438–440, 1970     

A study of the alkaloids ofSaussurea salsa andS. elegans

Conclusions 1. In the extraction ofS. salsa andS. elegans, the condensation of the neutral substances with ammonia takes place with the formation of products of a basic nature.2. FromS. elegans a new alkaloid elegantine C₂₃H₂₉O₅N has been obtained the saponification of which has given tyramine and a sesquiterpene lactone.Khimiya Prirodnykh Soedinenii, Vol. 4, No. 6, pp. 367–370, 1968
