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

Pak J Pharm Sci. 2021 Sep;34(5(Supplementary)):1963-1968.

Abstract

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.
