Abstract
Two regioisomeric meroterpenoids, Eugenial A and B, have been isolated from the fruits of Eugenia multiflora and their structures established on the basis of NMR evidences. They possess a phloroglucinol-monoterpene structure similar to the euglobals occurring in the sister genus Eucaliptus. A simple method to distinguish between regioisomeric pairs was pointed.
