The isolation from the epigeal part of Aconitum coreanum (Levi.) Rapaics, gathered in Primorgkii krai, of C20 diterpenoid alkaloids of the hetisine and atisine types and also of coryphine and coryphidine (containing a hexahydro-N-methylindole fragment unusual for this group of bases) has been reported previously. On continuing the chromatographic separation of the mixture of alkaloids from this plant, we obtained from chloroform-methanol (1:1) eluate fractions (after rechromatography on silica gel and elution with ethanol containing hydrochloric acid) the hydrochloride of base (1), which was identified as tangutisine (14-hydroxyhetisine) by spectral (IR, MS, PMR) and chemical (acetylation) analyses, representing the first isolation of tangutisine from A. coreanum. Additionally, through chromatographic separation on silica gel of the hexane-ether fraction (after elimination of accr and guan-fubases Z and F), we obtained crystalline alkaloid (2), which was identified as 2,11,13-triacetyl-14-hydroxyhetisine (guan-fu-base G) by spectral (MS, PMR) and chemical (saponification) analyses, a compound previously isolated from A. coreanum growing in China.
