Figure 2: (a) Effect of lycopene on inhibition of platelet aggregation induced by adenosine-5'-diphosphate. NS = Not significant versus Asp 140, using one-way ANOVA followed by post-hoc Dunnett Multiple Comparisons Test. ADP: Adenosine diphosphate. (b) Effect of lycopene on inhibition of platelet aggregation induced by collagen. Values represent the mean percent inhibition of aggregation and error bars represent SD; n = 12 per group. Asp 140 = Aspirin 140 ìmol/L; Lyc 4, Lyc 6, Lyc 8, Lyc 10 and Lyc 12 corresponds to 4, 6, 8, 10 and 12 ìmol/L of lycopene, respectively. PI=Platelet inhibition'
