Abstract

This study evaluated the antinociceptive and anti-edema properties of fractions of Coriandrum sativum Linn. (Apiaceae/Umbelliferae) leaves in mice. Ethyl acetate fractions (FAc) were obtained from dichloromethane extracts prepared from dried C. sativum (CS) leaves and stems. The effects of different concentrations of FAc on mice were observed using the open-field test, formalin-, capsaicin-, and carrageenan-induced paw edema tests, and the acetic acid-induced abdominal writhing test. Results from the carrageenan-induced paw edema test were subjected to a linear regression analysis and data from other assays were subjected to the Kruskal-Wallis test (followed by the SNK post hoc test). Dihydrocoriandrin (34.5%), coriandrin (14.4%), vitamin E (4.6%), and stigmasterol (7.9%) were identified in FAc. The number of squares the mice crossed in the open field test was decreased by 100 mg/kg and 300 mg/kg FAc (i.p.). The administration of 30, 100, and 300 mg/kg FAc induced fewer abdominal writhes than the control. In the formalin test, neurogenic pain was reduced by 20 mg/kg morphine and 30 and 100 mg/kg FAc, but not 5 mg/kg dexamethasone or 10 mg/kg FAc. Formalin-induced inflammatory pain was decreased by morphine, dexamethasone, and 30 and 100 mg/kg FAc. Morphine and 30, 100, and 300 mg/kg FAc significantly decreased the reaction time during the capsaicin test. Dexamethasone reduced both early and later phases of carrageenan-induced edema. Both 30 and 300 mg/kg FAc induced less edema than the control throughout the experiment. FAc showed antinociceptive, anti-edema and anti-inflammatory properties and it may be considered as a potential phytotherapeutic agent in the future. (AU)
