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

Figure 5

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 plasma lipid peroxidation induced by H₂O₂ or H₂O₂/Fe. The results represent 3–8 independent experiments and are expressed as means SE. The effects were significant according to ANOVA test, for peroxidation induced by H₂O₂: H. rhamnoides fraction-treated plasma versus A. melanocarpa extract-treated plasma (); H. rhamnoides fraction-treated plasma versus grape seed extract-treated plasma (); for peroxidation induced by H₂O₂/Fe: H. rhamnoides fraction-treated plasma versus A. melanocarpa extract-treated plasma (); H. rhamnoides fraction-treated plasma versus grape seed extract-treated plasma ().
