It also highlights the importance of screening of different types of monofloral honey
for their antimicrobial activity against specific bacterial strain.
A characteristic feature of honey from the Lazdijai District is monofloral honey from Onobrychis, which contains dominant pollen of this plant (52.
Three kinds of monofloral honey, lime (Tilia cordata), caraway (Carum carvi), and orchard, were identified in the samples from the Armona Geological Reserve.
The concentration of fructose and glucose as well as their ratio are considered useful indicators for the classification of monofloral honeys , being used all over the world in this main purpose.
Electrical conductivity (EC) is also an important measurement for the authentication of monofloral honeys .
The samples of monofloral honey were obtained from local production units, near Bucharest metropolitan area.
Solutions of the four monofloral honey samples (30% v/v) and the artificial honey (70% v/v) were prepared in sterile de-ionized water immediately prior to performing an assay and diluted with different volumes of sterile de-ionized water to give double the final concentration required in a volume of 25 ml.
The samples commercially marketed as monofloral honeys
were three from Eucalyptus (Myrtaceae), two from Baccharis (Asteraceae), two from Croton (Euphorbiaceae), one from Citrus (Rutaceae), one from Piptadenia (Fabaceae), one from Mimosa (Fabaceae), one from Lithraea (Anacardiaceae), one from Vernonia (Asteraceae), and one from Eryngeum (Apiaceae).

with multivariate analysis of their chemical profile and antioxidant activity.
Samples of Tetragonisca presented dominant pollen types of Carica papaya (Marilia-T), Eupatorium (Posse-T), Melilotus alba (Pedreira-T) and Piptadenia (Itaberaba-T), characterizing monofloral honeys (Figure 1 a-f).
Taking all honey samples into account, Apis produced monofloral honeys of Eucalyptus and Citrus in three localities (Amparo, Itaberaba, Lins).
In fact, numerous studies have been reported on the physicochemical parameters of honeys from all over the world [2,8,10,12,18] and several studies have been published on the physicochemical parameters of monofloral honeys
, from Romanian production areas especially from Transylvania [3,14].
