摘　　要：研究表明,长期受到阳光中紫外线的照射不仅会引起皮肤红斑、晒伤,还会造成体内的氧化应激及免疫抑制,甚至导致皮肤肿瘤的发生。近年来,绿茶茶叶中主要活性成分绿茶多酚的健康效应越来越受到人们的关注。许多研究指出,绿茶多酚具有促进微循环、抗氧化、抗炎症以及抗癌的作用。但在国内,绿茶多酚抗紫外线方面的研究仍然较少。本文从绿茶多酚抗炎、抗氧化、促进DNA修复等几个方面对其抗紫外线的机制作一综述,并且对含有绿茶多酚的防晒用品的实际应用前景进行展望。The UV radiation may induce erythema, oxidative stress, immune suppression and even skin cancer. In recent years, the most abundant and biologically active compounds in green tea, known as polyphenols, have caused wide attention because of their health effects. Green tea polyphenols can promote microcirculation, anti-inflammatory action, antioxidation, and DNA repair. In China, there is still less research focusing on the anti-UV radiation effects of green tea polyphenols. In this review, recent progress on the anti-inflammatory, anti-oxidant, and DNA-repair effects of green tea polyphenols against UV radiation has been reviewed. Meanwhile, the application of the sunscreen products containing green tea polyphenols has been evaluated.
