Abstract

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 $17.68{\pm}1.59{\sim}51.40{\pm}1.04$, $27.48{\pm}0.22{\sim}50.89{\pm}0.13$ and $30.79{\pm}0.55{\sim}45.17{\pm}0.83%$, 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 $0.27{\pm}0.12{\sim}11.38{\pm}0.57$, $0.27{\pm}0.02{\sim}0.82{\pm}0.27$ and $0.09{\pm}0.16{\sim}0.55{\pm}0.27%$, respectively. The capacities of preventing porcine pancreatic elastase (PPE) were $3.70{\pm}1.23{\sim}7.28{\pm}1.01$, $3.06{\pm}2.13{\sim}13.03{\pm}2.99$ and $6.00{\pm}0.96{\sim}9.71{\pm}0.44%$, 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.

본 연구에서는 Sophora japonica L. (S. japonica)학명의 콩과 식물 낙엽교목인 회화나무의 꽃, 열매, 가지 에탄올 추출물의 총 폴리페놀 함량 및 l,1-diphenyl-2-picryl-hydrazyl (DPPH) 라디칼 소거능 측정, 티로시나제 활성 저해력 측정 및 porcine pancreatic elastase (PPE) 저해력 측정을 통하여 기능성 화장품 소재로서의 활용 가능성을 확인하였다. 그 결과 총 폴리페놀 함량은 평균 각각 261.37 mg/g, 187.49 mg/g, 81.26 mg/g이며, DPPH 라디칼 소거능을 조사한 결과 50~1,000 mg/L 농도에서 회화나무 꽃 추출물은$17.68{\pm}1.59{\sim}51.40{\pm}1.04%$, 열매 추출물은 $27.48{\pm}0.22{\sim}50.89{\pm}0.13%$, 가지 추출물은 $30.79{\pm}0.55{\sim}45.17{\pm}0.83%$ 범위의 소거 활성을 나타내었다. 또한 같은 농도에서 티로시나제 저해능과 PPE 저해능을 실험한 결과 회화나무 꽃 추출물은 $0.27{\pm}0.12{\sim}11.38{\pm}0.57%$, $3.70{\pm}1.23{\sim}7.28{\pm}1.01%$ 열매 추출물은 $0.27{\pm}0.02{\sim}0.82{\pm}0.27%$, $3.06{\pm}2.13{\sim}13.03{\pm}2.99%$, 가지 추출물은 $0.09{\pm}0.16{\sim}0.55{\pm}0.27%$, $6.00{\pm}0.96{\sim}9.71{\pm}0.44%$ 범위로 티로시나제 저해능은 꽃 추출물이 높게 나타났다. 본 연구에서 회화나무의 피부개선에 미치는 효능, 효과를 살펴본 결과 꽃, 열매, 가지 추출물이 각 부위별로 효과가 상이하게 나타남을 알 수 있었다.
