The α-glucosidase inhibitory activity (IC50) of free and bound phenolic fractions (A) in different buckwheat samples and their main phenolics molecules (B). QUE, quercetin; RUT, rutin; KAE-3-O-RUT, Kaempferol-3-O-rutinoside. DIM, dihydromyricetin. Different uppercase letters (A,B) mean statistically significant differences in free and bound phenolic fractions of different samples. Different lowercase letters (a–e) mean statistically significant differences following different samples/analytes at the same fraction.
