In the present work, the anti-inflammatory and gastroprotective properties of ethanolic extracts of Stachytarpheta cayennesis (L.C. Rich) Vahl (Verbenaceae) were assessed. Chromatographic analysis of the crude ethanolic extract, SC01, revealed high concentrations of the iridoid ipolamiide, whereas the SC02, the second ethanolic extract, presented the arylpropanoid verbacoside as a major constituent. The oral administration of SC01 (100mg/kg) into Swiss mice failed to inhibit paw oedema and pleural exudation induced by carrageenan and zymosan, whereas SC02 (100mg/kg, p.o.) inhibited oedema and protein extravasation in all instances. Both extracts inhibited total leukocyte accumulation into the pleural cavity 4 and 24h after the intrathoracic (i.t.) injection of carrageenan, due to the inhibition of neutrophil and mononuclear cell influx, whereas only SC02 was able to inhibit leukocyte mobilization induced by …
