The purpose of this research was to examine the effect of the ehanol extracts of Sophora japonica L. (S. japonica). flowers, fruits and branches on skin enhancement with assessing anti-oxidative, whitening, and wrinkle enhancement effects. Results showed that l,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activities were 17.68 ± 1.59 ∼ 51.40 ± 1.04, 27.48 ± 0.22 ∼ 50.89 ± 0.13 and 30.79 ± 0.55 ∼ 45.17 ± 0.83%, respectively, in 50 ∼ 1,000 mg/L of concentrations. The capacities of inhibiting tyrosinase of ethanol extracts from S. japonica. flowers, fruits and branches were 0.27 ± 0.12 ∼ 11.38 ± 0.57, 0.27± 0.02 ∼ 0.82 ± 0.27 and 0.09 ± 0.16 ∼ 0.55 ± 0.27%, respectively. The capacities of preventing porcine pancreatic elastase (PPE) were 3.70 ± 1.23 ∼ 7.28 ± 1.01, 3.06 ± 2.13 ∼ 13.03 ± 2.99 and 6.00 ± 0.96 ∼ 9.71 ± 0.44%, respectively, in the case of 50 ∼ 1,000 mg/L of concentrations. It is concluded that the effects of S. japonica. flowers, fruits and branches on skin improvement are varied significantly.
