Anti-inflammatory activity of Maytenus senegalensis root extracts and of maytenoic acid.

Maytenus senegalensis (Lam.) Excell (Celastraceae) root extracts were investigated for their topical anti-inflammatory properties by measuring the inhibition of the Croton oil-induced ear oedema in mice. The highest anti-inflammatory activity was detected in the chloroform extract, which reduced the oedematous response with a potency similar to that of the NSAID reference drug indomethacin (ID(50)=84 and 93 microg/cm(2), respectively).
