The title compound, C(24)H(39)NO(6) [systematic name: (1α,6α,14α,16β)-N-ethyl-6,16-dimeth-oxy-4-meth-oxy-methylaconitane-1,8,14-triol], is a C(19)-diterpenoid alkaloid from the roots of Aconitum flavum Hand. The mol-ecule has an aconitane carbon skeleton with four six-membered rings and two five-membered rings. Both five-membered rings adopt envelope conformations. Two six-membered rings adopt ...

The aim of this paper was to seek an efficient method to preparative separation of alkaloid compounds from Aconitum coreanum (Guanbaifu), a well-known traditional Chinese medicinal plant for heart disease. Seven alkaloid compounds were successfully purified by pH-zone-refining counter-current chromatography with two-phase solvent system of petroleum ether-ethyl acetate-methanol-water (5:5:1:9, ...

BACKGROUND AND AIMS Reduction in female fitness in large clones can occur as a result of increased geitonogamous self-fertilization and its influence through inbreeding depression. This possibility was investigated in the self-compatible, bee-pollinated perennial herb Aconitum kusnezoffii which varies in clone size. METHODS Field investigations were conducted on pollinator behaviour, flowerin...

Three new bisditerpenoid alkaloids, navicularines A-C (1-3), and three known ones (4-6), were isolated from the ground parts of Aconitum naviculare. Their structures were elucidated by spectroscopic methods. All the new compounds were tested against five cell lines (HL-60, SMMC-7721, A-549, MCF-7, SW480). It was found that navicularine B exhibited certain cytotoxic activities in vitro, with IC5...
