The determination of the botanical/geographical origin of honey provides assurance of the product?s quality. Inthe present work, honeys from different ecoregions of Argentina were analysed, and the possible link betweenthe complete pollen profile of honey samples and their volatile composition was evaluated by multivariatestatistical tools. A total of 110 volatile compounds were found and semiquantified in honey samples.Redundancy analysis showed significant correlations between the volatile profile of honeys and their productionregion (P=.0002). According to the present results, 3,8-p-menthatriene; cyclopropylidenemethylbenzene;1,1,6-trimethyl-1,2-dihydronaphthalene; 1,2,4-trimethylbenzene; α-pinene; isopropyl 2-methylbutanoate;cymene; 2,6-dimethyl-1,6-octadiene; 3-methyloctane; 1-(1,4-dimethyl-3-cyclohexen-1-yl)ethanone; terpinolene;ethyl 2-phenylacetate; naphthalene and 7 unknown compounds could be used to classify Argentinean honeysaccording to their geographical origin with a prediction success of 96%. Moreover, it could be concluded thathoneys with Eucalyptus sp., Aristotelia chilensis and T. Baccharis pollen types presented some characteristic volatilecompounds which could be used as floral markers.
