The structures and distributions of more than 230 natural C_(19)-diterpenoid alkaloid and the assignments of ~(13)C-NMR dada of 170 compounds among them were listed. This report contains the two largest types, aconitine-type and lycoctonine-type.

• 最后以表格的形式报导了每个天然C_(19)-二萜生物碱的结构及其主要的植物来源,并将其中170余个生物碱的~(13)C-NMR化学位移数据分门别类,整理成表,以便于对相似化合物的~(13)C-NMR进行比较,这样对于分析鉴定C_(19)-二萜生物碱将大有帮助。
