In vitro anti-inflammatory activity of extracts from Potentilla supina in murine macrophage RAW 264.7 cells

Potentilla supina (Rosaceae) has traditionally been used to treat disorders of hemostasis, dysentery, malaria, bloody discharge and arthritis, and it has antinociceptive and anti-inflammatory properties. However, validity of the antiinflammatory activity has not been scientifically investigated so far. Therefore, the aim of this study was to investigate the anti-inflammatory potential of P. supina using the ethanolic extract of P. supina and its sub-fractions. To evaluate the anti-inflammatory effects of P. supina, we examined the inflammatory mediators such as nitric oxide (NO), inducible nitric oxide synthase (iNOS) and prostaglandin E2 (PGE2) in RAW 264.7 cells. Our results indicated that ethyl acetate fraction significantly inhibited LPS-induced NO, iNOS and PGE2 production in RAW 264.7 cells. This result showed that ethyl acetate fraction of P. supina is expected to be a good candidate for development into a source of anti-inflammatory agents.
