Twenty-four samples of monofloral Romanian honey (acacia, linden, rapeseed and sunflower) were analysed for their total phenolic and flavonoid contents, pH, free acidity, ash, electrical conductivity and color intensity. The analyses were performed in accordance with Romanian and EU standards and according to the methods in the literature. The results for color varied between 0.9-69.1 mm Pfund, for pH and free acidity between 3.54-4.44 and 4.7-15.7 meq kg-1, respectively. The values of ash and electrical conductivity were between 0.043-0.291% and 0.12-0.55 mS cm-1. The total phenolic content ranged from 14.50 mg GAE/100 g to 30.13 mg GAE/100 g while total flavonoid content ranged from 0.59 mg Q/100 g to 2.84 mg Q/100 g. The Pearson correlation analysis indicates positive significant correlations between color and total flavonoid content, ash and electrical conductivity, ash and total polyphenols content.
