Two new euglobals, G6 and G7 were isolated from the hexane fraction of the methanol extract of the leaves of Eucalyptus grandis. These have phloroglucinol-monoterpene structures. Both euglobals have a formyl-isovaleroyl phloroglucinol moiety fused with ?-terpinene. Their structures were elucidated on the basis of spectral evidences. © 1998 Elsevier Science Ltd.
