In vitro Antiinflammatory Activity of 23-Hydroxyursolic Acid Isolated from Cussonia bancoensis in Murine Macrophage RAW 264.7 Cells

We investigated the effect of various triterpenoids isolated from the Cussonia bancoensis. such as ursolic acid. 23-hydroxyursolic acid. 3-O-${\alpha}$-L -arabinopyranosyl-23 -hydroxyursolic acid. 3-O-${\beta}$-D-glucopyranosyl-23-hydroxy-ursolic acid and 28-O-${\alpha}$-L -rhamnopyranosyl(1-4)-${\beta}$-D-glucopyranosyl( 1-6)-${\beta}$-D-glucopyranosylester of 23-hydroxyursolic acid. have been evaluated on lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) release by the macrophage cell line RAW 264.7.
