Since ancient times, honey has been considered not only a sweet food but also known as a remedy against diseases, due to its antioxidant properties.

The purpose of this study was to assess the total phenolic and flavonoid contents from Romanian raw monofloral honey and to establish their correlations with several qualitative parameters. In 2019, 28 samples were harvested: 8 acacia; 7 linden; 5 rapeseed, 5 sunflower and 3 mint, then analyzed in accordance with standardized methods, to measure: color intensity, water insoluble solids content, refractive index, moisture content, solid substances content, total soluble substances content, specific gravity, pH, free acidity, ash content, electrical conductivity, total phenols content and total flavonoids content.

Pearson test shown several correlation levels of total phenols content with other compounds: strong positive with total flavonoids (r=0.76) and color intensity (r=0.72); moderate positive with free acidity (r=0.57), ash content (r=0.51) and electrical conductivity (r=0.53); weak negative with pH (r=-0.23).

For total flavonoids content, correlations were: strong positive with color intensity (r=0.81), ash content (r=0.76) and electrical conductivity (r=0.73); fairly strong positive with free acidity (r=0.65); low positive between total flavonoids content and moisture (r= 0.35).

The relevant levels of polyphenols and flavonoids identified in the analyzed honey demonstrate its antioxidant potential, as essential nutritional and sanogenic features in human nutrition.
