Abstract
The physicochemical properties, antioxidant activities and phenolic contents of seven types of Sudanese honeys derived from flowers of Acacia nilotica, Acacia seyal, Azadirachta indica, Cucurbita maxima, Balanites aegyptiaca, and two Ziziphus spina christi plant species were evaluated. The moisture content was in the range from 16.2 to 21.3, g/100 g honey, ash content from 0.121 to 1.205 g/100 g honey, nitrogen from 0.032 to 0.046 g/100 g honey while the corresponding protein content was 0.200 to 0.286 g/100 g honey. Total phenolic content varied from 4.44 to 201.08 mg/100 g honey as gallic acid equivalent. The values of the antioxidant activities were in a range from 3177 to 6247 μg for the lC

. No significant correlation was established between antioxidant activity and total phenolic contents.
