Abstract
Native to India, Bael is one of the earliest known species of fruit trees in the Rutaceae family (Ae gle marmelos).
The bael fruits have significant industrial and processing values in addition to its wellknown nutritional and traditional medicinal properties.Bael fruit's ability to promote and maintai n health is attributed to its fibre content, carotenoids, phenolics, terpenoids, coumarins, flavonoid s, and alkaloids.According to Gurvey's literature review, more research is required to determine t he mode of action of the bioactive chemicals that have been found, both in vitro and in vivo. The production of nanoparticles using plants has attracted attention from all around the world du e to its affordability, environmental friendliness, and wide range of uses. The current study exami ned the antibacterial potential of silver nanoparticles (AgNPs) derived from a methanolic extract of Aegle marmelos fruit. The antibacterial activity of solvent extracts (petroleum ether, chlorofor m, acetone, methanol, and aqueous) and AgNPs was assessed using the Agar well diffusion meth od. The maximum inhibitory activity against B. Cereus (16.17±0.50 mm) was demonstrated by the methanolic extract of A. Marmelos, which was followed by P. Aeruginosa (13.33 ± 0.62 mm) and E. Coli. The methanolic extract of A. Marmelos underwent phytochemical examination, which showed the presence of flavonoids, glycosides, alkaloids, tannins, saponins, and steroids. AgNPs synthesised using methanolic extract from A. Marmelos were characterised by X-ray diffraction, dynamic light scattering, atomic force microscopy, and UV-visible spectroscopy. The size range of the AgNPs was 159–181 nm, with a peak observed at 436 nm. When the antibacterial potential of green synthesised AgNPs was evaluated, B. Cereus (19.25±0.19 mm) showed the highest inhibitory activity, followed by P. Aeruginosa (16.50±0.30 mm) and S.
