Abstract

From the juvenile leaves of Eucalyptus blakelyi, a new euglobal, euglobal-Bl-1 (1), having a phloroglucinol-monoterpene structure, has been isolated along with the known euglobals-Ib (2), -Ic (3) and -IIa (4). The structure and stereochemistry of euglobal-Bl-1 (1) and the stereochemistry of euglobal-Ib (2) were established by spectroscopic evidence.
