Background/Objectives: In current trend biological synthesis of metallic nanoparticles is gaining importance because it is reliable and eco-friendly.

Methods/Statistical analysis: The present work leads to the synthesis of nanoparticles from 3mM and 5mM AgNO3 solution through aqueous leaf extract of Dysoxylum parasiticum as reducing as well as capping agent by employing boiling method and microwave irradiation method. Synthesized nanoparticles are characterized under UV-Vis spectroscopy at the range of 200-800nm.

Findings: Green synthesized silver nanoparticle showed zone of inhibition against tested microorganisms. The leaf extract shows higher antimicrobial activity found by disc diffusion method. Furthermore, determination of elemental silver was done by the Atomic Absorption Spectroscopy (AAS). The phytochemical constituent determination shows the positive results expect for the test for terpenoids and test for the reducing sugar.

Improvements/Application: Both Boiling Method and Microwave Irradiation Method are effective in synthesizing of silver nanoparticles using the leaves extracts of plants.
