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

Figure 6

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 autoperoxidation of blood platelets and platelet lipid peroxidation induced by thrombin. The results represent 3-4 independent experiments and are expressed as means SE. The effects were significant according to ANOVA test, for autoperoxidation: 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 ().
