Hypoglycemic, anti-inflammatory, and neuroprotective potentials of crude methanolic extract from L. - results of an in vitro study.

L., also known as babul, belonging to the Fabaceae family and the genus, is typically used for ornamental purposes and also as a medicinal plant found in tropical and subtropical areas. This plant is a rich source of bioactive compounds. The current study aimed to elucidate the hypoglycemic, anti-inflammatory, and neuroprotective potential of 's crude methanolic extract. The results of the in vitro antidiabetic assay revealed that methanolic extract of inhibited the enzyme α-glucosidase (IC: 33 μg mL) and α-amylase (IC: 17 μg mL) in a dose-dependent manner. While in the anticholinesterase enzyme inhibitory assay, maximum inhibition was shown by the extract against acetylcholinesterase (AChE) (637.01 μg mL) and butyrylcholinesterase (BChE) (491.98 μg mL), with the highest percent inhibition of 67.54% and 71.50% at 1000 μg mL, respectively. This inhibitory potential was lower as compared to the standard drug Galantamine that exhibited 82.43 and 89.50% inhibition at the same concentration, respectively. Moreover, the methanolic extract of also significantly inhibited the activities of cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX) in a concentration-dependent manner. The percent inhibitory activity of 5-LOX and COX-2 ranged from 42.47% to 71.53% and 43.48% to 75.22%, respectively. Furthermore, in silico, in vivo, and clinical investigations must be planned to validate the above-stated bioactivities of .
