Two new C-21 Daphniphyllum alkaloids, longeracinphyllins A (1) and B (2), have been isolated from the leaves of Daphniphyllum longeracemosum. Longeracinphyllin A (1) is a new daphnilongeranin B type alkaloid with a rearranged alpha,beta-unsaturated ketone group, and the structure is supported by X-ray crystal data. Longeracinphyllin B (2) is a new seco-10,17-daphnilongeranin B type alkaloid.
从长序虎皮楠(Daphniphyllum longeracemosum)的叶子中分离出了两种新的C-21虎皮楠生物碱,长序虎皮楠碱A(1)和长序虎皮楠碱B(2)。长序虎皮楠碱A(1)是一种新的具有重排α,β-不饱和酮基团的虎皮楠龙胺B型生物碱,其结构得到了X射线晶体数据的支持。长序虎皮楠碱B(2)是一种新的裂环-10,17-虎皮楠龙胺B型生物碱。
