-Amylase and -Glucosidase Inhibitory Activities of Phenolic Extracts from Eucalyptus grandis × E. urophylla Bark

Figure 3

Inhibitory activities of different solvent extracts from Eucalyptus bark on α-amylase (a) and α-glucosidase (b) (4 mg/mL). Inhibitory activities of ethyl acetate fraction (EB-E 1–7) on α-amylase (c) and α-glucosidase (d) (2 mg/mL); control = untreated enzyme; EB-H = hexane extract; EB-E = ethyl acetate extract; EB-B = n-butanol extract; EB-W = water extract. Bars express means ± SD (). RSD < 5%.
