Beschreibungen/Notizen

• This study was carried out to search for natural anti-oxidants and anti-inflammatory compounds from 5 medicinal plants (Carthamus tinctorius seed, Cyperus rotundus, Schizonepeta tenuifolia, Polygonatum odoratum var. pluriflorum, and Paeonia lactiflora). 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 (DPPHㆍ), 2,2-azino-bis 3-ethylbenzthiazoline-6-sulfonic acid (ABTSㆍ), ferric reducing antioxidant power (FRAP) and superoxide anion radical assays. C. tinctorius seed extracts showed the highest polyphenol and flavonoid contents as well as strong DPPHㆍ, ABTSㆍ, FRAP, and superoxide anion radical scavenging activity. Also, C. tinctorius seed extracts showed the highest nitric oxide (NO) production inhibitory effect. Theses results indicate that the C. tinctorius seed extracts can be used as a functional material due to their effective anti-oxidative and anti-inflammatory activities.
