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.

Metabolites of the pathogenic fungus Verticillium dahliae VI. Pentaketide metabolites and neutral lipids of virulent and avirulent strains

Summary A comparative study of the amounts of the phytotoxic pigment PKZh-1 and of extracellular and intracellular lipids in five strains and mutants ofVerticillium dahliae differing in virulence and in the nonpathogenic fungusV. lateritium has been made. A definite correlation has been found between virulence and PKZh-1 content.It has been established that the extracellular lipids are produced in considerable amounts by the virulent strains while in the avirulent mutants and inV. lateritium they are absent or present in only very small amount. The contents of neutral lipids in the mycelia of strains and mutants differing in virulence do not differ significantly. There are definite differences in the compositions of the neutral lipids and in the fatty-acid compositions of the individual classes of lipids.From the culture liquid of one of the avirulent strains (R-196), 3,6,8-trihydroxy-1,2,3,4-tetrahydronaphthalen-1-one has been isolated.V.

Investigation of the protein component of the lipopolysaccharide-protein complex ofYersinia pseudotuberculosis

It has been established by electrophoresis in polyacrylamide gel that the protein component of the lipopolysaccharide-protein complex ofYersinia pseudotuberculosis consists of two poly-peptides with molecular weights of 42,000–45,000 and 18,000–20,000. These polypeptides have been detected in the cell wall ofY. pseudotuberculosis as the main components. Protein fractions B-2 and B-3, differing with respect to solubility in phenol, were isolated from the LPPC ofY. pseudotuberculosis by extraction with hot 45% phenol. These protein fractions had the same polypeptide composition, which is characteristic for membrane proteins. B-3 included the LPS component and B-2 contained lipid A or fragments of it as impurity.
