A New Dimeric Secoiridoid Glycoside from the Leaves of Olea ferruginea Royle

摘要

A new dimeric secoiridoid glycoside, trivially named oleferrugine B (1), has been isolated from the AcOEt-soluble part of the MeOH extract of leaves of Olea ferrugineaRoyle. The structure of the isolated compound was established on the basis of ESI-MS fragmentation patterns, and 1D- and 2D-NMR techniques, including H-1- and C-13-NMR, HSQC, H-1,H-1-COSY, HMBC, and NOESY experiments, and by comparison with literature data.
