Direct Effects of (−)-Epicatechin and Procyanidin B2 on the Respiration of Rat Heart Mitochondria

Figure 2

Effect of (−)-epicatechin (a) and procyanidin B2 (b) on the respiration rate of isolated rat heart mitochondria in the State 2. Effect was expressed in % of initial respiration rate, which was  nmol O/min/mg protein (substrates, pyruvate and malate, P + M),  nmol O/min/mg protein (substrate succinate in the presence of amytal, S(+A)), and  nmol O/min/mg protein (substrates, palmitoyl-L-carnitine and malate, Pcarn + M). versus control, . The results were analysed with one-way analysis of variance (ANOVA) followed by Dunnett’s post hoc test.
