Hydrogen peroxide (H2O2; a), lipid peroxidation (LPO; b) and reactive oxygen species (ROS; c) of Neopyropia yezoensis at different temperatures (10 and 20 °C) and four different extraction methods using Sargassum horneri. Different letter on the bar indicates significant differences (p < 0.05). Error bars mean ± SD of triplicate. Control (without extract), S. horneri boiling extract (SBE), S. horneri ethanol extract (SEE), S. horneri soaking extract (SSE), and S. horneri autoclaving extract (SAE).
