[ALKALOIDS OF UNDERGROUND PARTS OF GEORGIAN FLORA'S ACONITUM ORIENTALE MILL. AND ACONITUM NASUTUM FISCH. EX REICHEMB AND THEIR BIOLOGICAL ACTIVITY].

The aim of research was to study underground parts of Aconitum orientale Mill and Aconitum nasutum Fisch exReichemb for the composition of biological active diterpenic alkaloids. The research object was underground parts of Aconitum species. Alkaloids sum was received from raw-material which was alkalined beforehand with chloroform extraction. From the results of research we established, that both species of Georgian flora's Aconitum contains alkaloids: lappaconitine, aconitine, karakoline. Underground parts of Aconitum orientale and Aconitum nasutum differ from eath other with composition of alkaloids spectrum. Underground parts of Aconitum orientale contains bases: ranaconitine, gigactonine, licoctonine, but underground parts of Aconitum nasutum contains: talitizamine, kamakonine, aconosine. Alkaloids' summary substances, which were received from underground parts of Aconitum species spread in Georgia, showed selective cytotoxic activity towards A-549 (lung carcinoma), DLD-1 (intestine adenocarcinoma), WS-1 (human normal fibroblasts).
