Four new C-diterpenoid alkaloids, 3-dehydroxyl-lipoindaconitine (1), 8-dehydroxyl-bikhaconine (2), 19R-acetonyl-talatisamine (3), and 16-hydroxyl-vilmorisine (4), were isolated from the roots of Aconitum ouvrardianum. Their structures were elucidated by spectral analyses, including ESI-MS, HR-ESI-MS, IR, UV, 1D and 2D NMR.
从滇南乌头的根部分离得到了4个新的C-二萜生物碱，分别为3-去羟基-脂乌头碱（1）、8-去羟基-滇乌碱（2）、19R-丙酮基-塔拉胺（3）和16-羟基-紫乌碱（4）。通过光谱分析，包括电喷雾电离质谱（ESI-MS）、高分辨电喷雾电离质谱（HR-ESI-MS）、红外光谱（IR）、紫外光谱（UV）、一维和二维核磁共振谱（1D和2D NMR）对它们的结构进行了鉴定。
