Green synthesis of silver nanoparticles using cloves (Sygzium aromaticum), cinnamon bark (Cinnamomum cassia) and tulsi (Ocimum teniflorum) leaves have been comparatively studied by different characterization tools, both in aqueous and powdered form. The uniformity in the concentration and physiochemical conditions has been maintained in all the three cases. The clove-based synthesized silver nanoparticles show the best outcomes in terms of stability, morphology, etc., whereas the cinnamon-based synthesized nanoparticles show the least standard of expected outcomes. It is here also noted that the synthesis has been carried out at normal pH, room temperature, and using very easily available instruments and apparatus. There has been intended to synthesize qualitative silver nanoparticles at ground level, using Indian plant extracts. Thus, the merit of this work is the process has been confined to very simple and basic requirements. The anti microbial applications have been analyzed and their efficiencies have been explained at both gram-negative and gram-positive types of bacteria.

Key words: Green synthesis, cloves, cinnamon, tulsi, characterization, gram-negative, gram-positive
