Antioxidant, Cytotoxic, and Toxic Activities of Propolis from Two Native Bees in Brazil: Scaptotrigona depilis and Melipona quadrifasciata anthidioides

Figure 1

Protective effects of ascorbic acid (standard antioxidant) and ethanol extracts of propolis from S. depilis and M. q. anthidioides against AAPH-induced hemolysis determined using a human erythrocyte suspension at 120 min (a), 180 min (b), and 240 min (c). Ethanol was employed as a negative control. The results are expressed as the mean ± SEM (standard error of the mean), . ignificantly different () compared with the AAPH group.
