Objective: To develop a new approach for the green synthesis of silver nanoparticles using aqueous leaves extracts of Heliotropium zeylanicum which has been proven active against clinically important microbial pathogens. Methods: Characterization was determined by using UV-vis spectroscopy, scanning electron microscopy (SEM) and Fourier Transform infrared spectroscopy (FTIR). Antimicrobial activity was screened by using disc diffusion method. Results: SEM showed the formation of silver nanaoparticles with an average size 4-30 nm. The significant antibacterial activity was showed against Proteus vulgaris. Conclusion: It can be concluded that the leaves of can be good source for synthesis of silver nanaoparticle which shows antimicrobial activity.
