This study was carried out to search for natural antioxidants compounds from 10 longevity plants (Panax ginseng(Korean mountain cultivated ginseng), Lycopersicon esculentum, Agaricus bisporus, Perilla frutescens, Allium sativum, Rubus coreanum, Allium tuberosum, Vaccinium corymbosum, Polymnia sonchifolia, Oryza sativa(Brown rice)) in Gyeongju. These plants were extracted with 70% ethanol. In order to measure total antioxidant activity of flavonoids, polyphenol content was measured. Radical scavenging activities of extracts were examined using a-a-Diphenyl-β-picrylhydrazyl (DPPH), 2,2-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), and superoxide anion radical assays. C. tinctorius seed extracts showed the highest polyphenol and flavonoid contents as well as strong DPPH, ABTS, and superoxide anion radical scavenging activity. Theses results indicate that 10 longevity plants can be used as a functional material due to their effective anti-oxidative activities.
