摘要: 从钩腺大戟中分出的八个阿替烷(Atisane)类型的二萜和一个贝壳杉烷(Kaurane)类型的二萜进行1H-H COSY,13C-1 COSY和1H-1H NOESY测定,使得它们的1H NMR和13C NMR谱的化学位移值得以归属.通过比较这两类二萜的13C NMR谱数据,观察到对于阿替烷类型二萜衍生物中碳20位上的甲基碳的化学位移总在14ppm左右,而贝壳杉烷类二萜,则出现在17ppm左右.这有助于区分现有的这两类二萜的基本骨架.

Abstract: The chemical shifts of the 13C NMR and 1H NMR spectra of eight atisane type diterpenes and one kaurane type diterpenc isolated from Euphorbia sieboldiana were assigned by their 13C-1H COSY, 1H-1H COSY and 1H-1H NOESY spectral studies, and the difference of 13C NMR chemical shifts between atisane diterpenes and kaurane diterpenes was found, which can be used to distinguish the atisane skeleton from kaurane skeleton easily.

Key words: Atisane diterpenes, Kaurane diterpenes, 2D NMR, Euphorbia sieboldiana
