From the roots of the plantConvolvulus subhirsutum Regel et Schmalh. have been isolated seven known alkaloids and one new one, for which, on the basis of spectral characteristics, a comparative study with known alkaloids of the tropane series, and synthesis, the structure of (+)-N-isopropyl-3-veratroyloxynortropane has been established.Institute of the Chemistry of Plant Substances of the Uzbek Academy of Sciences, Tashkent.

Two species of Berberis have yielded 10 isoquinoline alkaloids. In addition to known bases, two artifacts have been isolated — 8-trichloromethyldihydroberberine (I) and 8-trichloromethyldihydropalmatine. An x-ray structural analysis has been made of (1).Translated from Khimiya Prirodnykh Soedinenii, No. 6, pp. 889–893, November–December, 1996. Original article submitted April 15, 1996. 相似文献

The mass spectra of diptocarpaine, diptocarpamine, diptocarpiline, and diptocarpidine, isolated fromDipthychocarpus strictus, have been studied. These compounds have proved to be derivatives of alkylureas, the substituents in them being mainly methylthio-n-hexyl and methylsulfinyl-n-hexyl radicals and the products of their chemical transformation. It has been established that mass-spectrometric fragmentation of these compounds takes place with the formation of heterocyclic ions.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

The newdimeric alkaloid arundaphine, a tryptamine-tryptamine base, was isolated from roots and rhizomes of Arundo donax (Poaceae). Spectral data and an x-ray structure analysis established its structure as 1-[3-(2-dimethylaminoethyl)-5-hydroxy-1H-4-indolyl]-3-hydroxy-3-(2-methylaminoethyl)-2-indolinone. 相似文献
