Abstract

The alkaloids trisphaerine, tazettine, hippeastrine, lycorine, galanthamine, and pancratine were identified from Hymenocallis littoralis Salisb. (flora of the Upper Volta and Ivory Coast, first studied) based on physicochemical properties, spectral characteristics, and/or comparison with literature or authentic samples; eight bases were isolated, including previously obtained lycorine and tazettine, and for the first time trisphaeridine, hippeastrine (trisphaerine), pancratine (hemanthidine), galanthamine, and bases (I) and (II). Shoots of Aconitum saposhnikovii B. Fedtsch. (collected in Dolon Pass, Kirghiz SSR) yielded 0.54% total alkaloids via chloroform extraction; chromatography on alumina led to isolation of talatisamine, isoboldine, 14-acetyltalatisamine, and a new base 14-dehydrotalatisamine (first isolated from plant, identified by oxidation of talatisamine and comparison of mixed melting point, IR spectra, and TLC). From the epigeal part of Aconitum karacolicum Rapaics. (collected in upper reaches of R. Tyup, Kirghiz SSR, seed-ripening period), in addition to aconitine, songorine, isoboldine, and napelline N-oxide, a new base 12-acetylnapelline N-oxide was isolated and identified by reduction to 12-acetylnapelline.
