【 摘 要 】

Many species from Croton genus have been used in traditional medicine and its pharmacological activities demonstrated. Croton argyrophyllus Kunth, Euphorbiaceae, is a shrub that grows in the flora of Northeastern Brazilian. The essential oil of C. argyrophyllus leaves was tested in rodents (10-100 mg/kg, p.o.) in classical models of inflammation (carrageenan-induced paw oedema and peritonitis) and its chemical constituents were determined by GC-MS/FID analysis. Nitric oxide radical-scavenging activity and lipidic peroxidation were determined to evaluate the antioxidant capacity of the essential oil (0.001-100 µg/mL). Forty-two components were identified, among them, bicyclogermacrene (14.60%) and spathulenol (8.27%) were the most abundant ones. C. argyrophyllus essential oil reduced significantly the oedema (30 and 100 mg/kg, p<0.05) and, besides, reduced the carrageenan increase in mieloperoxidase activity (10, 30, and 100 mg/kg, p<0.001). The carrageenan-induced peritonitis was significantly reduced (p<0.001) by the essential oil (10, 30, and 100 mg/kg). The essential oil (100 mg/kg) reduces the total peritoneal lavage NOx- concentration (p<0.01). Nitric oxide radical generated from sodium nitroprusside was found to be inhibited by the essential oil (p<0.001). C. argyrophyllus essential oil was able to prevent Fe2+- or Fe2+ plus H2O2-induced lipid peroxidation (p<0.001). This study suggests that the anti-inflammatory effect of the essential oil of C. argyrophyllus observed in the present study can be related, at least in part, its antioxidant capacity.
