The objective of this work was to investigate the antiulcerogenic and anti-inflammatory activities of the essential oil from Pterodon emarginatus seeds.. The following tests were used: ulcers induced by ethanol, indometacin and HCl/ethanol, and pleurisy induced by carrageenan in Swiss albino rats. The rats were treated by the oral route with essential oil of P. emarginatus seeds.. The essential oil at 100, 300 and 500 mg/kg exhibited significant protection against ulcers induced by ethanol, indometacin and HCl/ethanol (P < 0.001). The essential oil caused a marked reduction in the exudate volume and inhibited leucocyte and neutrophil influx (P < 0.05) in carrageenan-induced pleurisy. Moreover, the essential oil significantly decreased nitric oxide (NO) and interleukin-1 (IL-1) levels, without affecting tumour necrosis factor-alpha production.. The results demonstrated the marked antiulcerogenic and anti-inflammatory effects of the essential oil from P. emarginatus, which are, at least in part, a consequence of NO and IL-1 modulation. P. emarginatus or its constituents might represent new therapeutic options to treat gastric ulcers and inflammatory diseases.
