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