| Background & aim: In Iranian traditional medicine, Crocus sativus L. has been defined as an exultant plant. The present study was undertaken to determine the effect of subchronic administration of aqueous and hydro-alcoholic extracts of Crocus sativus on mice.
Methods: The effect of subchronic i.p. administration of different doses of the aqueous extract (50, 100, 200, 400 mg/kg or water) and the hydro-alcoholic extract (100, 200, 400, 800 mg/kg or water) of Crocus sativus stigma on immobility, climbing, and swimming behaviors were evaluated in the forced swimming test in mice. Fluoxetine (20 mg/kg) and imipramine (15 mg/kg) were used as reference drugs. Additionally, the effect of both plant preparations on spontaneous activity was examined. The collected data was analyzed using One-way ANOVA.
Results: The aqueous extract at doses of 50 and 100 mg/kg produced a significant reduction in immobility along with an increase in climbing behavior which is similar to those which have been observed with imipramine. The hydro-alcoholic extract did not show significant effects on immobility, climbing and swimming behaviors of all studied doses, compared to control group. The aqueous extract of all studied doses and the hydro-alcoholic extract at dose of 1600 mg/kg decreased spontaneous activity.
Conclusion: The results of this study suggests that the aqueous, but not hydro-alcoholic, extract of Crocus sativus stigma from Estahbanat in Fars province, in subchronic administration possess an antidepressant-like activity which may be mediated through norepinephrine system. |
