Data are expressed as means ± SD (n = 3). Acarbose was used as a positive control in the α‐amylase and α‐glucosidase tests. Orlistat was used as a positive control in the lipase test. Differences within and between groups were evaluated by one‐way ANOVA followed by a multicomparison Dunnett's test: ****P < 0.0001, ***P < 0.001, compared with acarbose in α‐glucosidase and α‐amylase, and Orlistat in a lipase inhibition assay (IC_{50 =} μg mL⁻¹).
