    The aim of this study was to elucidate the anti-inflammatory activity of safflower (Carthamus tinctorius L.) ethanolic extract fractions (CFEFs). Butanol fraction had the strongest antioxidant activity, and all CFEFs, except for chloroform fraction, partly inhibited lipopolysaccharide (LPS)-induced nitrite production in RAW 264.7 cells. In the cell-free system, hexane and butanol fractions chemically quenched nitric oxide (NO). In addition, the iNOS mRNA transcription was suppressed by ethanol extract and hexane fraction in LPS-stimulated RAW 264.7 cells. Taken together, the inhibitory effect of CFEFs on NO production from LPS-stimulated RAW 264.7 cells, might be due to both the chemical NO quenching activity and the suppression of iNOS mRNA transcription partially. The synthesis of prostaglandin E₂ (PGE₂) was potently inhibited by ethanol extract to below basal label, and the transcription of cyclooxygenase-2 (COX-2), an enzyme involving in PGE₂ synthesis, was partially suppressed by ethanol extract and hexane fraction. Based on these results, CFEFs may be useful as an alternative medicine for the relief and retardation of immunological inflammatory responses through the reduction of inflammatory mediators, including NO and PGE₂ production.
