Hippophae rhamnoides L. Fruits Reduce the Oxidative Stress in Human Blood Platelets and Plasma

Figure 4

Effects of the phenolic fraction from fruits of H. rhamnoides (0.5–50 µg/mL; 15 min) on 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 test, for concentrations 5, 10, and 50 μg/mL (resting platelets); for concentrations 1, 5, 10, and 50 μg/mL (platelets activated by thrombin); for concentration 0.5 μg/mL (resting platelets and platelets activated by thrombin); for concentration 1 μg/mL (resting platelets).
