Introduction: Silver nanoparticles are better than other metal nanoparticles in terms of antimicrobial activity and stability. Recently, the biosynthesis method has been widely used, known for being ecofriendly and having lower toxicity compared to other methods of obtaining metal nanoparticles. This method is characterized by the use of active pharmaceutical ingredients contained in medicinal plants as stabilizers or bio reducers to produce silver nanoparticles. Methods: In this study, we synthesized silver nanoparticles using extracts from the upper parts of Cacalia hastata L., Thymus gobicus Czern., and Glycyrrhiza uralensis Fisch., which were collected from various provinces from Mongolia. These medicinal plants are used as bio reducing agents. We determined the most sensitive light absorption of each sample with purified silver nanoparticles using a UV-M51 ultraviolet spectrophotometer. Sizes and distributions were analyzed through Nanophox Particle Size Analysis, while morphological structure was examined using energy dispersive X-ray spectroscopy (EDX). The formations of nanoparticles were determined with instruments such as X-Ray Diffraction (XRD). Results: The appropriate formation times for nanoparticles were 24 minutes with Cacalia hastata L. extract and 16 minutes with Thymus gobicus Czern. extract. XRD analysis revealed characteristic peaks at 38.15°, 44.3°, and 64.55°, indicating the formation of a crystalline structure and confirming the presence of silver nanoparticles. Conclusion: Furthermore, these nanoparticles exhibited antibacterial activity against both S. aureus and E. coli.
