Anti-inflammatory properties and immunoadjuvant activitiy of Samanea saman extract

Samanea saman is a Leguminosae widely distributed in tropical regions, especially in Brazil. In folk medicine is used to treat skin infections, gastric inflammation and parasitic infestations, but there is no report in literature on its phytochemical. In order to confirm the utilization of this species in the traditional medicine, the antiinflammatory activity of the chloroform extract and the immunoadjuvant activity of the butanolic extract were investi gated . The chloroform extract exhibited a moderate control of the initial phase of inflammation, provoking an inhibition of edema formation similar to the re ference compound dexamethasone. The butanolic extract showed a relevant adjuvant potential in comparison with the commercial extract of Quillaja saponaria , a commonly used adjuvant for experimental vaccine formulations.
