Bisleucocurine A, a novel bisindole alkaloid from Leuconotis griffithii

, 2010
A novel bisindole alkaloid, bisleucocurine A (1), consisting of two strychnan skeletons with an N-1-C-17' and a C-12-C-2' bridges, was isolated from the leaves of Leuconotis griffithii and the structure was elucidated on the basis of spectroscopic data ...
