Fig. 3From: Antioxidant activities and oxidative stress inhibitory effects of ethanol extracts from Cornus officinalis on raw 264.7 cellsXanthine oxidase inhibitory effect of various concentrations of Cornus officinalis on RAW 264.7 cells. Cells were treated with Cornus officinalis at different concentrations (10, 50, and 100 μg/mL). After treatment for 24 h, xanthine oxidase activity was measured with a commercial kit. Values are the mean ± SEM of experiments in triplicate. Values expressed by different letters are significantly different at p < 0.05Back to article page
