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 and chemical transformation.
