Abstract:
Plant-based antimicrobial compounds have emerged as a blessing to medical sciences due to the multitude of bioactive phytochemicals or secondary metabolites, ease of availability and a broad spectrum of action with negligible adverse effects. Azadirachta indica (A. indica) is reported to possess a multitude of phytochemicals. In the present study, the phytochemical constituents of the aqueous extract of A. indica leaves were analysed qualitatively. The chemical nature of the extract and the structurally similar compounds present in it were analysed by Fourier transform infrared (FTIR) spectroscopy. Preliminary phytochemical analysis by qualitative biochemical tests revealed the presence of alkaloids, flavonoids, terpenoids, glycosides, phenols, steroids, tannins and saponins. Fourier transform infrared spectroscopic analysis revealed the presence of functional groups such as alcohols, carboxylic acid, amine salt, disubstituted alkenes, sulphates and halocompounds.
