Conclusions 1. Water-soluble polysaccharides have been isolated from the bark and stems ofAlcea hyrcana Grossh. with yields of 2.2% and 1.6%, respectively; they contain uronic acids, glucose, arabinose, and xylose.2.The quantitative amounts of these monosaccharides in samples of the isolated polysaccharides have been determined.Khimiya Prirodnykh Soedinenii, Vol. 6, No. 4, pp. 397–400, 1970 相似文献

Summary The chemical structure of a new cardiac glycoside, evonoloside, obtained from the seeds ofE. europaeus L. has been established. Evonoloside is cannogenol 3--L-rhamnopyranoside.Khimiya Prirodnykh Soedinenii, Vol. 3, No. 4, pp. 241–244, 1967 相似文献

Conclusions The cardenolide and coumarin composition ofC. varia L. and the closely related speciesC. hyrcana Pril.,C. cretica L., andC. orientalis Müll have been investigated. It has been shown that they all contain the cardiac glycoside hyrcanoside, with the exception ofC. orientalis, in which another, unidentified, glycoside, has also been found.A comparative study of some properties of hyrcanogenin (4-strophanthidin) and pachygenin (5-strophanthidin) connected with conformational features has been carried out.In the species studied, no less than five coumarins have been found of which umbelliferone, scopoletin, and daphnoretin have been isolated.Khimiya Prirodnykh Soedinenii, Vol. 5, No. 3, pp. 141–144, 1969 相似文献

Summary 1. The polarographic behavior of haploperine, haplopine, haplophyllidine, and perforine in Britton-Robinson buffer solutions and in (C2H5)4NOH solutions has been studied. Optimum conditions for their quantitative determination in solutions within the range of concentrations from 5×10–4 to 1×10–2 M have been found.2. A method for the separate quantitative determination of the alkaloids in the seeds ofH. perforatum has been developed.Khimiya Prirodnykh Soedinenii, Vol. 2, No. 5, pp. 333–337, 1966 相似文献
