dc.description.abstractThis study was conducted was to determine the potency of the aqueous honey extracts of three different species of bee using in vitro antioxidant capacity assays and their corresponding relationship with the phenolics and flavonoids contents. The 3 types of different in vitro antioxidant assays were ABTS scavenging assay, DPPH scavenging assay and FRAP reduction assay. The antioxidant capacity of the aqueous honey extracts were found to be increased for all antioxidant assay as the concentration increases (dose dependent), for ABTS (2,2’-azinobis-3-ethylbenzothiazoline-6-sulfonic acid) scavenging assay, DPPH (2,2-diphenyl-l-picrylhydrazyl) scavenging assay and FRAP reduction antioxidant potential. The total phenolic (TPC) and flavonoid content (TFC) were determined according to Folin-Ciocalteu method and aluminium chloride method respectively. The T.apicalis honey extract showed the highest phenolic and flavonoid content and strong antioxidant activity. The samples which contained the highest antioxidant activities (i.e honey extract of T.apicalis) is most likely as a consequences of their highest phenolic and flavonoids content compared with the remaining samples. TPC of the aqueous extracts with the highest value was produced by T.apicalis, followed by H.itama, G.thoracica at concentration of 1 mg/ml. TFC of the aqueous extracts varies, with the highest value was produced by T.apicalis at concentration of 1 mg/ml. The positive significant linear correlation was confirmed between the values for the TFC and TPC and antioxidant capacities of the honey aqueous extracts. Therefore, the aqueous honey extracts demonstrated a high antioxidant value and interestingly it was associated with the TFC and TPC of the tested honey samples.en_US
