Two new macrocyclic diterpenes, 2-epi-latazienone (4) and 15β-acetoxy-7β-nicotinoyloxy-3β,8α-di-(2-methylpropanoyloxy)-4αH,9αH,l1αH-lathyra- 5E,12E-dien-14-one (5), and three known lathyrane-type diterpenes (1-3) were isolated from Euphorbia laurifolia latex. Their structures were determined on the basis of a detailed analysis of their 1D and 2D NMR spectroscopic and mass spectral data.
从月桂叶大戟乳胶中分离出两种新的大环二萜，2-表拉替泽酮（4）和15β-乙酰氧基-7β-烟酰氧基-3β,8α-二（2-甲基丙酰氧基）-4αH,9αH,11αH-拉替拉-5E,12E-二烯-14-酮（5），以及三种已知的拉替烷型二萜（1-3）。通过对它们的一维和二维核磁共振光谱数据以及质谱数据进行详细分析，确定了它们的结构。
