Abstract

This study aimed to evaluate antioxidant capacity of honey samples that were collected from Blue Nile State, Sudan by determining total phenolic content (TPC) and total flavonoids content (TFC). Antioxidant activities were evaluated using 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity and ferric reducing power assay (FRAP). High-Performance Liquid Chromatography (HPLC) was used for the determination of sugars content. The results showed that the highest TPC was (85.7±1 mg GAE /100g), the highest TFC was found to be (55.14 ± 1.09 mg QE /100g) using quercetin equivalent (QE) as standard and the inhibition value of (DPPH) was (52.93 ± 0.44%). The FRAP showed the highest value of (281 μM TE/100g), also the results indicated that the honey contained fructose (38.6 ± 1.8 g/100g - 42.9 ± 1.3 gL100g), and glucose (30.4 ± 0.75 - 31.7 ± 0.68 g/100g). Protein content was found to be ranging between and 0.60% and 1.04%. In conclusion, the results showed that honey is a good source of antioxidants due to the presence of phenolic compounds, flavonoids and carotene. Also, an excellent source of the simple reducing sugars.
