Abstract
To investigate the antiulcer and antiinflammatory activities of the essential oil from Casearia sylvestris leaves (EOCS) the following tests were used: rat paw edema, granulomatous tissue test, vascular permeability, writhing test, gastric ulcer stress-induced and evaluation of gastric secretion (pylorus ligation test). The total yield of EOCS was 2.5% with LD50 of 1100 mg/kg in mouse. The major compounds identified using gas chromatography were caryophyllene, thujopsene, alfa-humulene, beta-acoradiene, germacrene-d, bicyclogermacrene, calamenene, germacrene B, spathulenol and globulol. The EOCS orally administered to the rats at 125 mg/kg resulted 36% of inhibition in carrageenan-induced edema in the rat paw assay (p<0.05, Student's t-test). However, both rat paw edema dextran-induced and vascular permeability assay using histamine showed no significant inhibition. Mice submitted to the writhing test using acetic acid presented 58% and 56% of inhibition in writhes with EOCS and indomethacin, respectively. Furthermore, EOCS inhibited 90% of stress-induced gastric ulcer, while cimetidine inhibited 70% (p<0.05, Student's t-test). The volume of gastric secretion in the group treated with EOCS was greater than the group treated with cimetidine. The EOCS also showed no changes related to H+ levels in the gastric secretion. With the overall results obtained in this study the authors suggest an anti-inflammatory activity for the EOCS of Casearia sylvestris beyond its anti-ulcer activity.
