Objectives: To evaluate the anxiolytic effect of Coriandrum sativum (CS) aqueous extract in mice. To compare the antianxiety activity of CS against standard drug diazepam (3 mg/kg). Materials and Methods: After obtaining Institutional Animal Ethics Committee approval, Swiss albino mice (18-25 g) of either sex were randomly divided into five groups of six animals each. Dried powder of CS leaves was boiled with distilled water, cooled, filtered, placed on a hotplate for complete evaporation, finally weighed and stored. The control group, test group, and standard drugs group received saline, CS extract (50, 100, and 200 mg/kg), diazepam (3 mg/kg), respectively, by oral feeding. The antianxiety effect was assessed by elevated plus maze (EPM) in mice. Results: In EPM, it implied that CS 50 mg/kg (Group III), 100 mg/kg (Group IV), and 200 mg/kg (Group V) significantly (P < 0.001) increases the number of entries in open arms compared to control. The time spent in open arms also increased in all the doses of CS extract significantly. Conclusion: The current study demonstrates statistically significant dose-dependent antianxiety activity of CS leaves.
