The data shown are mean values ± SD (n = 3). α-amylase, α-glucosidase, and lipase inhibition are presented as IC50 in mg/mL, and anti-lipoxygenase effect as the percentage of inhibition (at the concentration of 30 mg/mL). DM—dry mass. Different letters (a–d) in the same column denote a significant difference among varieties, according to Tukey’s test. p < 0.05.
