OBJECTIVE: Roxb. (Liliaceae), a traditional herbal medicine, has been used as an aphrodisiac and brain tonic in Asian countries. The aim of the present study is to investigate the antidepressant-like effect of standardized hydroethanolic extract ofroot and its possible mechanisms.

MATERIALS AND METHODS: Mice administered with vehicle, imipramine (15 mg/kg/day; i.p.), andextract (AAE) (25, 50, and 100 mg/kg/day; i.p.) for 14 days were subjected to behavioral tests including forced swimming test (FST), tail suspension test (TST), and open-field test (OFT) on the 14day. In order to explore the underlying mechanism behind an antidepressant effect of AAE, the brain monoamine levels, oxidative stress parameters, and serum corticosterone levels were monitored.

RESULTS: Our results indicated that pretreatment of AAE (25, 50, and 100 mg/kg) for 14 days statistically significantly (<0.01) demonstrated antidepressant-like effect as evidenced by reduced immobility time in both FST (105, 78.6, and 53.6 s) and TST (97.6, 73.5, and 54.67 s), with no significant change in spontaneous locomotor activities as observed in OFT. Further, the behavioral improvement was supported by the statistically significantly (<0.05) enhanced levels of monoamines and reduced corticosterone level along with amelioration of oxidative stress in AAE-treated animals as compared to vehicle control group.

Conclusion: Our findings clearly demonstrated the antidepressant-like effect of AAE, which might have been mediated through the modulation of monoaminergic system and by regulating hypothalamic-pituitary-adrenal axis with amelioration of oxidative stress.
