Abstract

Two new secoiridoid glycosides, oleuricines A (1) and B (2), together with five known triterpenoids, beta-amyrin, oleanolic acid, erythrodiol, urs-2beta,3beta-dihydroxy-12-en-28-oic acid, and beta-maslinic acid, were isolated from the EtOAc-soluble part of EtOH extract of the leaves of Olea europaea L. The structures of these compounds were elucidated by various spectroscopic methods, including intensive 1D, 2D NMR, and HR-ESI-MS techniques.

摘要

从油橄榄叶乙醇提取物的乙酸乙酯可溶部分中分离出两种新的裂环环烯醚萜苷，油橄榄素A（1）和B（2），以及五种已知的三萜类化合物，β-香树脂醇、齐墩果酸、羽扇豆醇、乌苏-2β，3β-二羟基-12-烯-28-酸和β-马斯里酸。通过各种光谱方法，包括1D、2D NMR和HR-ESI-MS技术，阐明了这些化合物的结构。
