Objective: The objective of the study was to investigate the anxiolytic activity of petroleum ether, alcohol and water extracts, obtained from the flowers of Sphaeranthus indicus Linn, in mice. Materials and Methods: Elevated plus maze (EPM), open field test (OFT) and foot-shock induced aggression (FSIA) were the screening tests used to assess the anxiolytic activity of the extracts on mice. Diazepam (1 mg/kg) served as the standard anxiolytic agent. Results: The animals receiving extracts or diazepam (1 mg/kg) showed an increase in the time spent, percent entries and total entries in the open arm of the EPM; increased ambulation, activity at centre and total locomotion in the OFT; and decreased fighting bouts in the FSIA, suggesting anxiolytic activity. Petroleum ether extract (10 mg/kg), alcoholic extract (10 mg/kg) and water extract (30 mg/kg) resulted in prominent activity in the mice. Petroleum ether extract (10 mg/kg) resulted in more prominent anxiolytic activity in the EPM and OFT than ethanolic or water extracts, but was less than that produced by diazepam (1 mg/kg). Conclusion: Petroleum ether extract of S. indicus flowers produces prominent anxiolytic activity in mice.
