Abstract

The objectives of this study were to investigate the antioxidant activity and anti-wrinkle effect of Rhamnus yoshinoi methanol extract (RYME) in a cell-free system. The total polyphenol and flavonoids contents in RYME were 538.4 and 196.3 mg/g, respectively. The electron-donating ability of RYME at 100 μg/mL was 92.5%, while its collagenase and elastase inhibitory effects at 8,000 μg/mL were 53.4 and 41.7%, respectively. In comparison, collagenase and elastase inhibition of the positive control vitamin C were 51.0 and 32.7%, respectively. The present study demonstrated that RYME has high antioxidant activity and effectively inhibited the activities of collagenase and elastase.
香菇甲醇提取物抗氧化活性及抗油效果
研究了鼠李甲醇提取物(Rhamnus yoshinoi methanol extract, RYME)在无细胞体系中的抗氧化活性和抗皱作用。总多酚含量为538.4 mg/g,总黄酮含量为196.3 mg/g。RYME在100 μg/mL浓度下的给电子能力为92.5%,在8000 μg/mL浓度下的胶原酶和弹性酶抑制作用分别为53.4和41.7%。阳性对照维生素C对胶原酶和弹性酶的抑制率分别为51.0%和32.7%。本研究表明,RYME具有较高的抗氧化活性,并能有效抑制胶原酶和弹性酶的活性。
