- Abstract
- Anti-inflammatory activity of the extracts of Hibiscus manihot was investigated through the evaluation of its inhibitory effect on the production of inflammatory biomarkers (i-NOS, COX-2) in RAW264.7 murine macrophage cells. Among the sequential solvent fractions (hexane, dichloromethane, ethyl acetate, n-butanol and water), the fractions of dichloromethane (1 μg/ml) and ethyl acetate (5 μg/ml) showed potential inhibitory activities on i-NOS and COX-2 activity in RAW264.7 cells. These results suggest that Hibiscus manihot might have an anti-inflammatory activity through the suppression of inflammatory markers.
