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

Figure 7

Effects of the phenolic fraction from fruits of H. rhamnoides (50 µg/mL; 15 min), A. melanocarpa extract (50 µg/mL, 15 min), and grape seed extract (50 µg/mL, 15 min) on generation in resting blood platelets and blood platelets activated by thrombin. The results represent 3–6 independent experiments and are expressed as means SE. The effects were significant according to ANOVA test, for resting platelets: H. rhamnoides fraction-treated platelets versus A. melanocarpa extract-treated platelets (); H. rhamnoides fraction-treated platelets versus grape seed extract-treated platelets (); for peroxidation induced by thrombin: H. rhamnoides fraction-treated platelets versus A. melanocarpa extract-treated platelets (); H. rhamnoides fraction-treated platelets versus grape seed extract-treated platelets ().
