Résumé

The objects of this research were the aboveground and underground parts of Vinca rosea L., a species of periwinkle introduced in Western Georgia. The sum of alkaloids and biologically aactive fractions of monomeric alkaloids were obtained by liquid-liquid extraction, precipitation with petroleum ether (I), polybuffer distribution (II) and 10% acetic acid (III). 14 known compounds were identified by LC-MS/MS and GC/MS: Low molecular weight compounds (М+226, М+202, №1,2, М+168) and alkaloids Ajmalicine, Tetragidroalstonine, C20-dihydrova llesiahotamine, C19-C20 Vallesiahotaminole, Vallesiahotamine lacton, Polyneuridine, Pericy clivine, Lochnerame, Norharmane, Vidorosine, Vindolinine, Isovindolinine, Akuammicine. The cytotoxicity of monomeric alkaloids was evaluated for A-549 (cells of the lung cancer line), DLD-1 (cells of the rectal adenocarcinoma line) and W-1 (cells of the normal human fibroblast line). All three substances (I, II, III) showed pronounced cytotoxic activity.
