Abstract. The chemical composition of honey varies according to the quality of the harvested nectar. The aim of the study was to determine the qualitative and quantitative composition of honey from different regions in Algeria. A qualitative and quantitative analysis was carried out on honey polyphenol extract with the characterization of the majors groups and the determination of the amount of total polyphenols. The results indicate that the honey polyphenol extracts have different rates of phenolic compounds (Flavonoids, Tannins and Cardenolides). The polyphenol extracts present a concentration of 0.32, 0.4, 0.76 and 0.39 mg GAE/100 g for the extract of Mascara, Oran, Jijel and Tlemcen respectively. The different types of tested honey present a variable composition on phenolic compounds, which allowed us to determine the different therapeutic properties of honey.
