The objective of this study was to evaluate the anti-inflammation effect of extract of Carthamus tinctorious seed, on skin obtained from Gyeong buk, Korea. Regulatory mechanisms of cytokines and nitric oxide (NO) involved in immunological activity of Raw 264.7 cells. Tested cells were pretreated with 70% ethanol extracted of Carthamus tinctorious seed and further cultured for an appropriated time after the addition of lipopolyssacharide (LPS). During the entire experimental period, 5, 10, 25 and 50 μg/ml of Carthamus tinctorious seed showed no cytotoxicity. In these concentrations, ethyl acetate layer of ethanol extracted Carthamus tinctorius seed (CT-E/E) inhibited the production of NO and prostaglandin E₂ (PGE₂), tumor necorsis factor-a (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) expression of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2). At a 50 μg/ml level of CT-E/E, PGE₂, iNOS and COX-2 inhibition activity were shown 60%, 38%, and 42%, respectively. In addition, CT-E/E reduced the release of inflammatory cytokines including TNF-α, IL-1β and IL-6. These results suggest that Carthamus tinctorious seed extracts may be a potential anti-inflammatory therapeutic agent due to the significant effects on inflammatory factors.
