摘要: 从阿勒颇侧大戟和巨枝大戟全草中分别得到的一个巨大戟烷型二萜酯和一个倍半萜甙,利用1H-1H COSY,HMQC,RMBC等2D NMR技术归属了所有质子和碳的化学位移信号,并准确指定了二萜酯中每个酯基以及倍半萜甙中糖的连接位置.

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 1H 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.

Key words: Ingenane ester, Sesquiterpene glucoside, 2D NMR, Chemical shifts
