Green tea, prepared from the leaves of Camellia sinensis L., is a beverage that is popular worldwide. Polyphenols in green tea have been receiving much attention as potential compounds for the maintenance of human health due to their varied biological activity and low toxicity. In particular, the contribution of antioxidant activity to the prevention of diseases caused by oxidative stress has been focused upon. Therefore, in this study, we investigated the effects of (-)-epigallocatechin 3-O-gallate and (-)-epigallocatechin 3-O-gallate, which account for a large fraction of the components of green tea polyphenol, on oxidative stress-related renal disease. Our observations suggest that green tea polyphenols have a beneficial effect on pathological states related to oxidative stress of the kidney.
绿茶是由山茶属植物的叶子制成的一种饮料,在全世界都很受欢迎。由于其具有多种生物活性且毒性低,绿茶中的多酚已作为潜在的维持人类健康的化合物而受到广泛关注。特别是,抗氧化活性对预防由氧化应激引起的疾病的贡献受到了关注。因此,在这项研究中,我们研究了(-)-表没食子儿茶素 3-O-没食子酸酯和(-)-表没食子儿茶素 3-O-没食子酸酯对与氧化应激相关的肾脏疾病的影响,这两种物质占绿茶多酚成分的很大一部分。我们的观察结果表明,绿茶多酚对与肾脏氧化应激相关的病理状态具有有益的影响。
