Abstract

Twelve compounds have been isolated from the methanolic extract of the whole plant of Eucalyptus globulus Labill namely, stigmasterol (1), stigmasterol 3-O-b-D-glucopyranoside (2), ursolic acid (3), a-amyrin (4), a-amyrin acetate (5) 4',5,7-trimethoxykaempferol (6), genistein (7), naringenin (8), catechin (9), apicatechin (10), octyl-b-D-glucopyranoside (11), 7,8-dihydroxycoumarin (12), respectively. Their chemical structures were established on the basis of spectroscopic methods 1D (1H and 13C) NMR and 2D (COSY, HMQC and HMBC) NMR in addition to mass spectrometry and comparison with literature data.
