title: Melissopalynological and volatile analysis of honeys from Corsican Arbutus unedo habitat.
abstract: Thirty Corsican "autumn maquis" honeys were characterized by the typical combination of autumnal taxa: Arbutus unedo, Hedera helix, Smilax aspera, Rosmarinus officinalis, and two Asteraceae pollen forms. Corsican origin was characterized by the diversity of the taxa's biogeographical origins and significant presence of Castanea sativa and Quercus sp. Volatile fractions of "autumn maquis" honeys were dominated by isophorone and 3,4,5-trimethylphenol. The latter is reported in A. unedo honey for the first time. Otherwise, both A. unedo flower and "autumn maquis" honeys exhibited high contents of isophorone derivatives. H. helix honey exhibited phenylacetaldehyde, benzyl nitrile, 3-hydroxy-4-phenylbutan-2-one and nonanal as major compounds, which were scarcely represented in the studied "autumn maquis" honey samples.
