Coumarin and Secoiridoid Glucosides from Bark of Olea africana and Olea capensis

Abstract

Coumarin glucosides, esculin (1) and scopolin (2), were isolated from the bark of Olea africana MILL. (O. europaea L. subsp. africana (MILL.) GREEN) while isoscopoletin-β-D-glucoside (magnolioside) (3) was isolated from the bark of Olea capensis L. The secoiridoid glucoside oleuropein (4) was also isolated from both species.
