采用超氧化物歧化酶(SOD)活性测定和红细胞溶血试验评价红田苹果果肉、皮内葡萄浆果果皮和石井蜜柑果皮提取物的抗氧化活性。红田苹果果肉和红果葡萄果皮中的超氧化物歧化酶活性均较高，但红田苹果果肉中红细胞的溶血延迟最大，其次是红果葡萄果皮和石地蜜柑果皮。用人皮肤成纤维细胞研究了这些水果提取物对紫外线的保护作用。与未经处理的对照相比，红田果肉提取物提高了细胞对紫外线的存活率。讨论了红场苹果中多酚类物质的参与。(C)2007爱思唯尔有限公司。保留所有权利。
Antioxidant activity in the extracts of Redfield apple flesh, Pione grape berry skin, and Ishiji satsuma mandarin skin was evaluated by a superoxide dismutase (SOD) assay and hemolysis of red blood cell assay. Although SOD activity was higher in both the Redfield apple flesh and Pione grape berry skin, hemolysis of the red blood cells was delayed most in the Redfield apple flesh, followed by the Pione grape berry skin and Ishiji satsuma mandarin skin. The protective effects of extracts from these fruits against ultraviolet rays were also examined using human skin dermal fibroblasts. The Redfield flesh extract increased the percentage of cell viability against ultraviolet rays compared to the untreated control. The participation of polyphenolics in Redfield apples is discussed.
