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
