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

Figure 2

Effects of the phenolic fraction from fruits of H. rhamnoides (0.5–50 µg/mL; 15 and 60 min) on plasma protein carbonylation induced by H₂O₂ (a) and plasma protein carbonylation induced by H₂O₂/Fe (b). Data represent means standard error (SE) of 4. 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 concentration 50 μg/mL (for 15 min) (a); for concentrations 10 and 50 μg/mL (for 60 min) (a); for concentrations 0.5, 1, 5, and 10 μg/mL (for 15 min) (a); for concentrations 0.5, 1, and 5 μg/mL (for 60 min) (a); for concentration 50 μg/mL (for 15 min) (b); for concentrations 5, 10, and 50 μg/mL (for 60 min) (b); for concentrations 0.5, 1, 5, and 10 μg/mL (for 15 min) (b); for concentrations 0.5 and 1 μg/mL (for 60 min) (b).
