| Abstract: | A new diterpene ester (5, 20-O-diacetylingenol-3-O - (2'E, 4'Z)- teteradecadienoate) and a known sesquiterpene glucoside(Roseoside)were isolated from the whole part of Euphorbia petiolata and E.macroclada, respectively. The position of the three esters of compound (1) and one glucose moiety of compound (2) were umbiguously assigned on the basis of HMBC experiment, and all the iH and 13C NMR chemical shifts of the two compounds were also assigned by 2D NMR techniques, such as H- 1H COSY, 13C - 1H COSY, HMQC and HMBC. |
