Possible neuropharmacological effects of Adenia trilobata (Roxb.) in the Swiss albino mice model

Background Known colloquially as akandaphal in Bangladesh, Adenia trilobata has some traditional uses. Its leaves and stems are extracted with pure methanol (MEATL, MEATS) and fractioned by n-hexane (NFATL, NFATS). The in vivo anxiolytic activity was evaluated by elevated plus maze (EPM) testing and hole-board test (HBT), whilst the locomotor activity was examined using the open-field test (OFT) and hole-cross test (HCT) and the antidepressant activity was assessed with the forced swimming test (FST) and the tail suspension test (TST). Results Regarding the anxiolytic activity, the 400-mg/kg doses of MEATL, NFATL, MEATS and NFATS exhibited maximum percentages of entry into the open arm of 33.85%, 32.23%, 30.06% and 41.84%, respectively, compare with the diazepam (69.33%). During HBT, MEATL (400 mg/kg) and NFATL (400 mg/kg) demonstrated 51.67 ± 0.88 and 57.67 ± 3.18 instances of head-dipping relative to diazepam (64.33 ± 3.16), whilst the locomotor activity showed a dose-dependent reduction in square movements and number of hole crossings. During FST and TST, the NFATL (400 mg/kg) exhibited rates of 43.32% and 57.71% time spent immobile, whilst fluoxetine experienced rates of 54.79% and 55.74%. Conclusion Adenia trilobata could be a potential component for the treatment of neuropharmacological defects. Further study is required.
