Effects of the phenolic fraction from fruits of H. rhamnoides (0.5–50 µg/mL; 15 min) on O2 −∙ generation in resting blood platelets and blood platelets activated by thrombin. Data represent means of 4–6 donors ± standard error (SE). The effect of five different concentrations of the tested fraction (0.5, 1, 5, 10, and 50 μg/mL) was statistically significant according to ANOVA I test, p < 0.05 for concentrations 5, 10, and 50 μg/mL (resting platelets); p < 0.05 for concentrations 1, 5, 10, and 50 μg/mL (platelets activated by thrombin); p > 0.05 for concentration 0.5 μg/mL (resting platelets and platelets activated by thrombin); p > 0.05 for concentration 1 μg/mL (resting platelets).
