“…Wang, which led to the discovery of three new hetisine-type C 20 -diterpenoid alkaloids bearing a N,O-mixed semiacetal moiety. Fourteen known diterpenoid alkaloids, named as delconine [5], delsoline [6], lycoctonine [7,8], delsemine A [8], delsemine B [8], deltatsine [9], anthranoyllycotonine [10], methyllycaconitine [11], delcosin [8,12], pacidine [13], 18-methoxygadesine [14], Jiufengtine [15], gigactonine [16], dehydrodelsoline [17], were isolated as well. This paper described the separation and structural elucidation of the new alkaloids.…”
