Antimicrobial, Antioxidant, Anti-Inflammatory, and Cytotoxic Activities of Propolis from the Stingless Bee Tetragonisca fiebrigi (Jataí)

Figure 2

Human erythrocytes incubated at 240 min with ascorbic acid and EEP of T. fiebrigi (25–125 μg/mL). (a) Hemolytic activity of treatments without the presence of AAPH and erythrocytes incubated only with 0.9% NaCl as control. (b) Hemolysis assessment after addition of AAPH in erythrocytes incubated with ascorbic acid and EEP. (c) Concentration of malondialdehyde (MDA) in nmol/mL after adding the oxidizing agent in erythrocytes incubated with different concentrations of treatments. * represents statistically significant results () when the treated group was compared to the AAPH group (erythrocytes incubated only with oxidizing agent).
