ABSTRACT

Terminalia chebula is a medicinal tree having immense importance in the Ayurvedic System of Medicine. The decoction of fruit is given to infants for digestive disorders even before the plant was discovered by the scientific community. In the current experiment, monometallic silver and zinc nanoparticles were synthesized by using different plant parts which include seed, fruit pulp, bark and leaf extracts. The nanoparticles synthesized were further evaluated for changed antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus Subtilis. All four plant parts resulted in silver nanoparticle synthesis and showed absorption peaks at 434 nm for leaf, 453 and 492 nm for bark and 419nm for fruit pulp while a peak at 400nm, 450nm for seeds, which confirmed the synthesis of the silver nanoparticles. The research confirmed the plant Terminalia to be efficient for silver nanoparticle synthesis. In addition zinc oxide nanoparticles were also synthesized using only leaf from the plant which resulted in dual peak at a wavelength of 326 nm and 357nm which confirmed the synthesis of nanoparticles from Zinc in addition to color change observed in the solution from green solution to cream colored paste which on further heating in muffle furnance converted to fine powder. XRD analysis further confirmed the zinc nanoparticle of size in the range of 22-83nm. Antimicrobial analysis revealed significant zones of inhibition using Terminalia authenticating the plant to be a great bio-resource to result in nanoparticle synthesis of all types.
