heteratisine/aconitum

The title compound, C(29)H(37)NO(6), was isolated from Aconitum zeravschanicum and exhibits anti-arhythmic activity. It is a derivative of the diterpenoid alkaloid heteratisine and as such the core framework of the mol-ecule contains four six-membered, three seven-membered and one five-membered

Extensive chromatographic separations performed on the basic (pH=8-10) chloroform soluble fraction of Aconitum heterophyllum resulted in the isolation of three new diterpenoid alkaloids, 6β-Methoxy, 9β-dihydroxylheteratisine (1), 1α,11,13β-trihydroxylhetisine (2), 6,15β-dihydroxylhetisine (3), and

Two new, rare heteratisine-hetidine-type bisditerpenoid alkaloids designated as trichocarpines A 1 and B 2, together with twelve known compounds have been isolated from the whole plants of Aconitum tanguticum var. trichocarpum. Their structures were elucidated by spectroscopic data interpretation

Nineteen compounds were isolated from the whole plants of Aconitum tanguticum by means of various of chromatographic techniques such as silica gel, ODS, sephadex LH-20 and preparative HPLC, and their structures were elucidated as syringin (1), vanillic acid-4-O-beta-D-allopyranoside (2), (E)

Aconitine is a highly toxic diterpenoid alkaloid occurring in plants of the Aconitum genus. Aconitine is known to shift the voltage-dependence of the voltage-dependent Na(+) channel towards hyperpolarized direction, thereby leading to a permanent activation of the channel. 6-benzoylheteratisine is a
