This study was conducted to compare anti-inflammatory effect of Robinia pseudoacacia L. using different extraction methods (water extraction, ethanol extraction and high temperature extraction). We investigated anti-inflammatory effect of Robinia pseudoacacia L. extract (RP1, water extract; RP2, ethanol extract; RP3, high temperature extract) on lipopolysaccharide (LPS)-stimulated inflammation using Raw 264.7 cell. Cells were treated with various concentrations (12.5, 25, 50, 100 or 200 ㎍/㎖) of water extract, ethanol extract and high temperature extract. Cytotoxicity was not observed on Raw 264.7 cells, LPS-stimulated production of NO (nitric oxide), PGE2 (prostaglandin E2) and cytokines (TNF-α, IL-6 and IL-1β) was reduced by RP3 treatment more than RP1 and RP2. In conclusion, these results indicated that inflammation on Raw 264.7 cells was improved by RP3. Treatment of RP3 could be used to natural medicine for improving inflammatory response. However, further experiment is required to observe how the high temperature extraction at 500℃ for 48 h influences on alteration of active ingredient in Robinia pseudoacacia L., and conducts the inflammation signal pathway on Raw 264.7 cells.
