Diterpenoid alkaloids from Aconitum tanguticum

Abstract Tanaconitine ( 1 ), a novel Aconitum alkaloid with a C 29 skeleton, together with six known diterpenoid alkaloids, was isolated from the roots of Aconitum tanguticum . The structure of 1 was elucidated to be 17-dehydroxyl-3′a( cis -1′-methyl-3′,3′a,7′,7′a-tetrahydro-1 H -indol-6′(2 H )-one)-naviculine A by spectroscopic analysis. Download full-size image
