摘要
对绿茶、葡萄籽和巴西大樱桃等20种植物提取物对酪氨酸酶的抑制作用以及其抗氧化能力(清除羟基自由基和超氧阴离子自由基的能力)进行了研究。实验结果表明,20种样品均表现出不同程度的酪氨酸酶抑制作用和抗氧化能力,其中绿茶、巴西大樱桃和葡萄籽提取物表现出极强的酪氨酸酶活性抑制率,且抑制活性远高于熊果苷;同时这3种植物提取物也表现出显著的清除羟基自由基和超氧阴离子自由基的能力,具有应用于美白化妆品的潜力。
Tyrosinase inhibiting activity and anti -oxidizing capacity （scavenging activity against hydroxyl free radicals and super - oxidizing anionic free radicals in vitro） of extracts of twenty kinds of plant material, including green tea, grape seed and Brazil cherry were investigated. Experimental results showed that, all the extracts of twenty kinds of plant material display tyrosinase inhibiting activity and anti - oxidizing capacity in vitro with different extent;while the extracts from green tea, grape seed and Brazil cherry display very strong tyrosinase inhibiting activity, which are much higher than that of arbutin. Further, the above - mentioned three extracts display significant scavenging activity against hydroxyl free radicals and super- oxdizing anionic free radicals in vitro. Thus the three kinds of plant material have the potential to be used in whitening cosmetics.
