From: Insulin secretion and α-glucosidase inhibitory effects of dicaffeoylquinic acid derivatives
Inhibitory effects of the dicaffeoylquinic acid derivatives on α-glucosidase inhibitory activities. Effect of A 3, 5-DCQA, B 4, 5-DCQA, C 1, 4-DCQA, D 3, 4-DCQA, E 1, 5-DCQA, and F acarbose (positive control) on the α-glucosidase inhibitory activities, compared with that of the control (0 μM), as determined by the α-glucosidase assay (n = 3 independent experiments). The data are presented as the mean ± SEM. *P < 0.05 compare with not-treated group
