Impact of chrysin and its derivatives on platelet activation in platelet-rich plasma. Human platelet-rich plasma was treated with vehicle control [0.1% (v/v) DMSO] or a range of concentrations of chrysin (A,B), thio-chrysin (C,D), Ru-chrysin (E,F) and Ru-thio-chrysin (G,H) for 5 minutes prior to the addition of 0.5 μg/mL CRP-XL in an optical aggregometer. The platelet aggregation was monitored for 5 minutes. The traces shown are representative of three separate experiments. The maximum aggregation obtained with vehicle control at 5 minutes was taken as 100% to calculate the level of aggregation for chrysin and its derivatives-treated samples. Cumulative data represent mean ± S.D. (n = 3). *Indicates significance with respect to controls and #indicates significance with respect to the respective chrysin concentrations, p values shown (**,## p < 0.01 and ***,### p < 0.001) are as calculated by one-way ANOVA using Graphpad Prism.
