Figure 7

The standardized extract from Camellia sinensis (CS), at concentrations ranging from 0.1 to 100 μg/mL, significantly decreased chemiluminescence in human neutrophils, as related to the PMA-stimulated cells, indicative of an antioxidant potential. a: versus spontaneous (spont.), ; b: versus spont., ; c: versus spont., ; d: versus spont., ; e: versus spont., ; f: versus control (cont.), ; g: versus cont., ; h: versus cont., ; i: versus cont., ; j: versus cont., (one-way ANOVA and Newman-Keuls as the post hoc test).
