Abstract

The crude ethanol extracts and their solvent-partitioned fractions derived from the leaf and twig of Viburnum dilatatum Thunb. were investigated for their 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging efficacy. The results showed that the butanol-soluble fraction () exhibited higher anti-oxidant activity than the crude ethanol extract () in the DPPH assay model. Then, the effects of the same extract samples on the production of nitric oxide were examined in LPS-stimulated RAW264.7 cells. Although the hexane and methylene chloride-soluble fraction showed a weak anti-oxidant activity, they exhibited potent inhibitory activity of NO production above 50 % at a concentration of . The hexane-soluble fraction also showed the inhibitory effect on mRNA expression of pro-inflammatory mediators such an TNF-, IL-, IL-6, iNOS and COX-2 in LPS-stimulated RAW264.7. These results suggest that the solvent extracts of Viburnum dilatatum Thunb. could be used as an anti-irritation ingredient.
