The known diterpenoid alkaloids karacoline, karakanine, songorine, napelline, 12-acetylnapelline, cammaconine, and a new 7,17-secoalkaloid of the lycoctonine type, secokaraconitine, were isolated from tubers of Aconitum karacolicum. An x-ray structure analysis of the new alkaloid was performed. 相似文献

Summary Relative difficulty of saponifying an acetoxy group at C1 and ease of acylation of a hydroxy group in this position as compared with a hydroxy group C10 has been shown for alkaloids with a lycoctonine skeleton.The anomalously easy saponification of a C1-acetoxy group in karakolidine acetates is due to the influence of the neighboring C13-hydroxy group.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

In the course of a further study of the alkaloids of the epigeal part of Aconitum turczaninowiia new alkaloid has been isolated, which has been named turpelline. A structure for turpelline has been proposed on the basis of a study of its IR, mass, PMR, 13 C NMR, and 2D COSY spectra. 相似文献

The known alkaloid lepenine and the new diterpene alkaloid akirine have been isolated from the epigeal part ofAconitum kirinense Nakai. To establish the structure of akirine, its spectral characteristics have been studied and an x-ray structural analysis has been made. It is 1α,8β-dihydroxy-16β-methoxy-9β,14β-methylenedioxy-3β,4β-epoxy-N-ethylaconitane — the first diterpene alkaloid with a lycoctonine skeleton containing a 9,14-methylenedioxy group and a β-oriented substituent at C14. 相似文献

Aconitine, mesaconitine, and a new alkaloid, which has been called altaconitine, have been isolated from the total alkaloids of the epigeal part ofAconitum altaicum. Altaconitine has the structure of 8-acetoxy-14-benzoyloxy-2,3,13,-15-tetrahydroxy-1,6, 16-trimethoxy-4-methoxymethy-N-ethylaconitan, which was established on the basis of a study of IR, PMR,13C NMR, and mass spectra and by the x-ray structural method.Institute of Chemistry, Mongolian Peoples' Republic Academy of Sciences, Ulan-Bator.

Summary We have isolated from the tubers ofAconitum karakolicum collected in the Kirghiz SSR, Kungei Alatau range, songorine, napelline, a base with mp 159–160°C, and the new alkaloids karakoline and a base with mp 222–224°C.The results of a study of the chemical reactions and spectral characteristics of karakoline have shown that it consists of a lycoctonine skeleton with N-ethyl and C4-methyl groups, hydroxyls at C1, C8, and C10 and a methoxy group at C15.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.
