The current study emphasized on assessment of Antioxidant, Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE) inhibitory activity of the crude methanolic and chloroform leaves extracts along with their isolated compounds derived from Azadirachta indica. Phytochemical analysis revealed the manifestation of ancillary metabolites like alkaloid, anthraqinones, catechins, flavonoids, phenolic compounds, saponins, tannins and steroids. Methanolic crude extract of Azadirachta indica leaves revealed comparable antioxidant activity as that of quercetin and propyl gallate. As far as enzyme inhibitory activity was concerned, a significant AChE enzymes inhibition was observed. These findings confirm the traditional use of Azadirachticha indica as medicinal plant in the treatment of mental ailments and anti-inflammatory illnesses. Chloroform crude extract and isolated compounds showed weak antioxidant and enzyme inhibitory activities.
