Abstract :
The composition and properties of natural honeys difer with plant species on which the bees forage and the climatic conditions
of the production areas. In Ethiopia, Amhara and Tigray are neighboring regions consisting of diferent agricultural activities and
blossoms from diferent types of vegetations which may infuence the natural composition and hence the properties of honey. So,
the aim of the current study was to assess the quality of honey from selected districts of the two regions. In the study, 18 composited
honey samples were collected from six selected districts and analyzed for selected physicochemical parameters and antioxidant and
antimicrobial activities. Te analyses of physicochemical parameters were carried out following standard procedures of IHC and
QSAE.Te antioxidant activity was determined by analyzing the RSA using DPPH while the antibacterial activities were determined
by the agar well difusion method. Te moisture, ash content, electrical conductivity, pH, free acidity, reducing sugar, and sucrose
content of the honey samples were found to be in the range 16.34 ± 0.26 to 19.83 ± 0.43 %, 0.08 ± 0.00 to 0.45 ± 0.03 %, 0.19 ± 0.00
to 0.89 ± 0.03 mS/cm, 3.79 ± 0.04 to 4.20 ± 0.01, 19.56 ± 1.13 to 38.11 ± 1.54 meq/kg, 62.10 ± 0.48 to 66.37 ± 0.20 %, and 1.35 ± 0.08
to 5.96 ± 0.10 %, respectively. Te total phenolic content ranged from 1165.60 ± 23.45 to 1854.83 ± 10.47 mg/kg with antioxidant
activity of 21.64 ± 0.26 to 36.12 ± 0.52 AEAC/100 g. Te total phenolic contents showed strong correlation with RSA. Furthermore,
all honey samples showed an antibacterial activity varying from 23.23 ± 0.12 to 28.84 ± 0.24 mm.
