Effect of the dicaffeoylquinic acid derivatives on the GSIS in INS-1 cells. Effect of A 3, 5-DCQA, B 4, 5-DCQA, C 1, 4-DCQA, D 3, 4-DCQA, E 1, 5-DCQA, and F gliclazide (positive control) on the GSIS in INS-1 cells following 1 h of treatment, compared with the control (0 μM). The data are presented as the mean ± SEM (n = 3). *P < 0.05 compare with not-treated group
