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.
