Assessment of Antioxidant Activity of Spray Dried Extracts of Psidium guajava Leaves by DPPH and Chemiluminescence Inhibition in Human Neutrophils

Figure 4

Modulatory effect of different concentrations of the extracts studied on ROS production in human neutrophils stimulated with PMA, determined by luminol-dependent chemiluminescence assay. (a) Conc. Ext. (concentrated extract) (b) MA 80, (c) MDEA 80, and (d) CD 80. Data expressed as the integrated area of CL 0–20 min. The figure is representative of three independent experiments with similar profiles performed in duplicate.
