The Antioxidant Capacity of Monofloral Eucalyptus Flower Honey and Weed Honey Obtained from Jerash and Al-Zarqa Jordanian Governorates
Honey contains natural antioxidants that can help to get rid of free radicals and improve our health.
The antioxidant capacity of honey is determined by its chemical makeup. The antioxidant capacity
of Monofloral honey, including Eucalyptus flower honey and Weed honey obtained from different
Jordanian governorates (Jerash and al-Zarqa) were examined using the phenolic contents (GAE),
DPPH free radical scavenging test (%), and Ferric reducing/antioxidant power assay (FRAP). The
Folin?Ciocalteu assay was used to assess the total phenol components in terms of the Gallic acid
equivalent (GAE) in mg/g. Results showed that the Eucalyptus flower honey, and weeds honey
both obtained from Jerash governorate followed by weeds honey obtained from Al-Zarqa
governorate have the highest phenolic contents among the honey samples with the values of
(10.6734 + 0.006) mg/g, (10.43889 + 0.012) mg/g and (10.1345+ 0.004) mg/g; respectively. The
DPPH scavenging assay as compared to BHT scavenging (reference control) 59.61%, has
demonstrated that the eucalyptus flower honey obtained from Al-Zarqa governorate and weeds
honey obtained from Jerash governorate have exhibited the highest DPPH scavenging among
honey samples with the values (12.8734+ 0.008)% and (11.5635+ 0.006)% respectively.
Moreover, the reducing power tests of the reference compound ascorbic acid (0.751 mg/ml) have
demonstrated that the weeds honey and eucalyptus honey both obtained from Jerash governorate
have exhibited the highest reducing power with values of (15.8857+ 0.002) mg/ml and (16.8787+
0.004) mg/ml respectively. It is important to note that honey has varying levels of antioxidant
activity depending on its source and content.
