The topical antiinflammatory activity of three extracts at increasing polarity (n-exane, chloroform, and methanol) from the leaves of Rosmarinus officinalis L. (Labiatae) has been tested using the croton oil ear test in mice. Both the n-hexane and the chloroform (CE-1) extracts from the leaves showed a dose-dependent activity, the last one possessing an antiinflammatory potency similar to that of indomethacin, the nonsteroidal antiinflammatory drug used as a reference drug (ID50 = 83 and 93 mu g/cm(2), respectively). The bioassay-oriented fractionation of CE-1 led to the identification of tritepenes, ursolic acid, oleanolic acid, and micromeric acid as the main antiinflammatory principles. Furthermore, the CE-1 extract obtained from the residue of the steam distillation of the leaves (extract A) showed the same antiinflammatory potency of CE-1, suggesting this waste product as a source of antiinflammatory products.
