V. Venkateswarlu et al., 13-O-ACETYLVAKHMATINE, A NEW DITERPENOID ALKALOID FROM THE SEEDS OF CONSOLIDA-AMBIGUA, Journal of natural products, 58(10), 1995, pp. 1527-1532
Vakhmatine [1] and the new diterpenoid alkaloid 13-O-acetylvakhmatine
[3] have been isolated from the polar alkaloidal fractions of the seed
