Two new C19-diterpenoid alkaloids, straconitines A (1) and B (2), were isolated from the roots of Aconitum straminiflorum. Their structures were elucidated as 14-benzoylducloudine D (1) and 6-hydroxy-14-benzoylducloudine D (2) based on spectroscopic analysis, including IR, ESI-MS, HR-ESI-MS, 1D, and 2D NMR.
从细叶乌头的根中分离出两种新的C19 - 二萜生物碱，草乌碱甲（1）和草乌碱乙（2）。基于红外光谱（IR）、电喷雾离子化质谱（ESI-MS）、高分辨电喷雾离子化质谱（HR-ESI-MS）、一维核磁共振（1D NMR）和二维核磁共振（2D NMR）等光谱分析，确定它们的结构分别为14-苯甲酰基杜乌碱D（1）和6-羟基-14-苯甲酰基杜乌碱D（2）。
