We quantified total phenolic and flavonoid contents, and evaluated several antioxidant activities using assays for ferric reducing antioxidant power, total antioxidant activity(phosphomolybdenum reducing ability), 1,1-diphenyl-2-picrylhydrazyl and thiobarbituric acid reactive species. Also, extracts were tested for their ability to inhibit a-amylase and α-glucosidase activity.Results: The total phenolic and total flavonoid contents in the free phenolic extract of BF were significantly greater than in the bound phenolic extract. Also, all the antioxidant activities considered were significantly greater in the free phenolic extract than in the bound phenolic extract. In the same vein, the free phenolic-rich extract had a significantly higher percentage inhibition against α-glucosidase activity(IC50= 28.5 mg/mL) than the bound phenolic extract(IC50= 340.0 mg/mL). On the contrary, the free phenolic extract(IC50= 210.0 mg/mL) had significantly lower inhibition against α-amylase than the bound phenolic-rich extract(IC50= 190.0 mg/mL).Conclusion: The phenolic-rich extracts of BF leaves showed antioxidant potentials and inhibited two key carbohydrate-metabolizing enzymes in vitro.展开更多
