Abstract
AbstractThis study was aimed to compare the antioxidant and cytoprotective effects of hot‐water and enzyme‐extracted constituents of Protaetia brevitarsis seulensis powder. The products of enzymatic extraction had 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH)‐radical‐scavenging activity, cytotoxic effects, and provided cytoprotection against H2O2 and intracellular reactive oxygen species. Enzymatic extraction improved DPPH‐radical‐scavenging activity relative to hot‐water extraction (P < 0.05), with inhibition rates of 33% at 500 μg/mL and 35% at 1000 μg/mL. Cell viability ranged from 100 to 122%, and was higher for hot‐water than for enzymatic extraction (P > 0.05). Hot‐water extraction achieved greater cytoprotection against H2O2 than enzymatic extraction. However, enzymatic extraction achieved greater antioxidant and cytoprotective activity against reactive oxygen species than hot‐water extraction. These results provide evidence of the antioxidant and cytoprotective effects produced by enzymatic extraction of the active ingredients from Protaetia brevitarsis seulensis powder.
