Enterohormone levels in the basolateral side after apical stimulation of pig intestinal samples with different purified compounds, for 60 min. (a) PYY secretion in the duodenum, (b) CCK secretion in the duodenum, (c) GLP-1 secretion in the ascending colon. Results are expressed in arbitrary units (A.U.), which are values normalized versus the control and represent mean ± SEM. * p < 0.05 vs. control, # p < 0.1, t-test. n = 7–9. C-, negative control vehicle-treated; Cat, catechin; Epi, epicatechin; B2, B2 procyanidin dimer; GA, gallic acid; PCA, protocatechuic acid.
