영문 초록

It is generally understood that natural substances render antioxidant effects. Some of the widely known antioxidant are carotinoids such as β-carotene, lycopene and lutein, flavonoids like anthocyanin, catechin, resveratrol and proanthocyanidin, and also isoflavons such as genistein, daidzein and glycitein. For instance, fruits such as tomatoes, watermelons, grapefruits contain profusion of lycopene, and carrots, sweet potatoes, pumpkins and mangos β-carotene, and spinach and cabbages such carotinoid like lutein. Polyphenol and catechin are rich in green tea and grapes, and flavonoids like resveratrol are contained in cocoa, red grapes, lingonberries, blueberries, mulberries and bilberries. Moreover, tofu, soy milk and miso are abundant sources of genistein, and beans are of isoflavon like daidzein. Furthermore, vegetables such as carrots, pumpkin seeds, sweet potatoes, pomegranates, strawberries, kale, broccoli, grapes, red wine, squash, clove, cinnamon, oregano, turmeric, cocoa, cumin, parsley, basil, ginger and thyme also contain ample supply of diverse sulfating agents including astaxanthin, quercetin and glutathione. Hence, I have arrived at various outcomes by measuring inhibitory activities of chemical, instead of natural, substances like genistein, diosmetin, saponarin, daidzin, gallocatechin, rutin, quercetin, kaempferol, equol, dihydroglycitein, on DPPH.
