The objectives of the present study were to georeference three sampling zones in the districts of Nueva Cajamarca, Chazuta and Saposoa, to determine the physicochemical characteristics (pH, total acidity, wa, humidity, soluble solids, density, electrical conductivity, ash, reducing sugars) and finally to determine the polyphenolic profile of bee honey from the study zones. A Randomized Complete Block Design - RCBD with three replicates was applied. The samples of bee honeys came from three zones: Nueva Cajamarca district (localities of Shambuyaco, Tumbaro, Vista Alegre), Chazuta district (localities of Aguano Muyuna, Shilcayo, Chazuta), Saposoa district (localities of San Andres, Montevideo, Shima) apiaries of the ecosystem of the Alto Mayo, Bajo Mayo and Central Huallaga basin, with a significance level of α=0.05, the reliability of the data was evaluated by the coefficient of variation (CV) and the coefficient of determination (R2). Comparative Tukey tests were also carried out. The physical-chemical analyses showed significant differences (P<0.05) for all compounds except for water activity (P>0.05). The physical-chemical composition was expressed in pH in the range of 3.53 - 3. 72; total acidity 29.52 - 30.82%; density 1.41 - 1.45 g/cm3 and moisture 19.40 - 22.23%, fructose in the range of 30.31 - 32.24% and glucose 32.07 - 33.35% and 64% as invert sugar, electrical conductivity 0.41 - 0.72 µS/cm, soluble solids 70.88 - 74.91%, ash 0.16 - 0.32%. Finally, the Principal Compound Analysis of the physicochemical variables showed that at least eight principal components (moisture, glucose and soluble solids associated with a second component pH, ash, electrical conductivity, fructose and water activity) contributed to the classification correlating with the geographical area. The phenolic compounds catechin (1.22±0.39), chlorogenic acid (1.17±0.65) are the most relevant. Statistically, the phenolic components of syringic acid, rutin and quercetin do not present significant differences (P>0.05) with the others. Samples from the district of Nueva Cajamarca (0.59±0.63) and the district of Chazuta (0.58±0.44) were found to have higher concentrations of phenolic compounds than samples from the district of Saposoa (0.57±0.51). Coumaric acid was not detected because it was below the detection limit of the chromatographic equipment.
