Anxiolytic, antidepressant and inhibitory effect on MAO isoenzymes by Bougainvillea glabra flower extract in rats.

Main aim of current study was to determine the anxiolytic and antidepressant potential of Bougainvillea glabra Extract (BVE). The effects were investigated by using Open-Field-Test (OFT), Light-and-Dark Model (LD), Hole-Board (HB) and Forced-Swimming-Test (FST). Different doses for BVE were given to Wistar-Rats and compared with Control and Diazepam. Data has been collected by simple observations of animal behaviors in mentioned models. Collected data was analyzed by SPSS-22 version. In OFT (number of squares travelled), significant differences noted between Control and BV100mg/kg (p=0.001), Diazepam and BV100mg/kg (p=0.0001), Diazepam and BV200mg/kg (p=0.015), Diazepam and BV300 mg/kg (p=0.002). In LD-Test, significant differences were noted between Control and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001), Diazepam and BV100mg/kg, 200mg/kg (p=0.0001), Diazepam and BV300mg/kg (p=0.028). In HB-Test by head dips, significant differences noted between control group and BV100mg/kg and 200mg/kg (p=0.0001), Control group and BV300mg/kg (p=0.005). For number of head dips, significant differences noted between Diazepam and BV100mg/kg, 200mg/kg and 300mg/kg (p=0.0001). In FST, significant differences were observed between Control group and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001), Fluoxetine and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001). It is observed that MAO-A and MAO-B are inhibited by BVE. Study demonstrates that BV flowers have anxiolytic and antidepressant activities. [ABSTRACT FROM AUTHOR]
