The extract yield was maximized as 44.47% under the temperature of 79.86°C, ethanol concentration of 56.84% and solvent to sample ratio 25.58 mL/g. The maximum value of electron donating ability was 85.46% at 46.38°C, 57.06% of ethanol concentration and 27.71 mL/g of solvent to sample ratio. The maximum value of tyrosinase inhibitory effect was 69.37% at 37.5°C, 47.71% of ethanol concentration and 16.03 mL/g of solvent to sample ratio. The maximum value of SOD-like activity was 48.36% in 66.12°C, 70.35% of ethanol concentration and 29.13 mL/g of solvent to sample ratio. Estimated conditions for the maximized extraction including yield, electron donating ability and SOD-like activity were 20-30 mL/g in ratio of solvent to sample, 25 - 85% in ethanol concentration, and 40 - 90°C in extraction temperature. 收起
