Four new Daphniphyllum alkaloids, daphlongamines A-D (1-4), were isolated from the fruits of Daphniphyllum longeracemosum. Their structures were characterized by spectroscopic methods, especially 2D NMR techniques. A single-crystal X-ray diffraction analysis was used to confirm the stereochemistry of 3. Remarkably, this is the first report of aconitine- and veatchine-type diterpenoid alkaloids from the genus Daphniphyllum.
从长序虎皮楠的果实中分离出了四种新的虎皮楠生物碱,即长序虎皮楠胺A-D(1-4)。通过光谱方法,尤其是二维核磁共振技术对它们的结构进行了表征。采用单晶X射线衍射分析确定了3的立体化学结构。值得注意的是,这是首次从虎皮楠属植物中报道乌头碱型和藜芦碱型二萜生物碱。
