Two new lycoctonine type C19-diterpenoid alkaloids, swatinine-A (1), and swatinine-B (2), along with four known C19-diterpenoid alkaloids, foresticine (3), neoline (4), delvestine (5), and chasmanine (6), were isolated from the aerial parts of the Aconitum laeve Royle. The structures of compounds 1 and 2 were deduced on the basis of spectroscopic techniques (EI-MS, HREI-MS, H NMR, C NMR, HMQC, ...
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, ...
SHIPING c., SHAN S.], TANAKA H. and SHOYAMA Y. Effects of culture temperature on microtuber formation of Aconitum carmichaelii Debx. and aconitine -type alkaloid contents BIOTRONICS 27, 15-20, 1998. The clonally propagated Aconitum carmichaelii Debx. was used for the investigation of microtubering. The rooting condition of propagated shoots affected the establishment of transplantation to soil ...
From the roots of Aconitum vulparia Rchb., collected in Prüm (Germany), a new norditerpenoid alkaloid, named alexhumboldtine, has been isolated along with the known norditerpenoid alkaloids lappaconitine, anthranoyllycoctonine, lycoctonine, puberaconitine, ajacine, and septentriodine. The structure of alexhumboldtine was established on the basis of 1H, 13C, DEPT, homonuclear 1H COSY, NOESY, HSQ...
