Mentha spicata is an essential aromatic and medicinal plant.The family of mint is Lamiaceae. The medicinal value of plants lines in bioactive of phytochemical constituents that produce different Physiological action on the human body. The most important bioactive phytochemical constituents are Tannin, Alkaloids, Saponins, flavonoids, carbohydrates ,terpenoid, glycosides. The aim of the study was to develop the synthesis of silver nanoparticles using mint plant leaves extracts. The fresh suspension of plant extract was yellowish green in colour. However after the addition of silver nitrate solution, the suspension showed a colour change in Yellowish green to dark brown in colour after 24 hours of incubation at room temperature. The antibacterial activity of the mint leaves extract against the gram positive and gram negative bacteria synthesized silver nanoparticles from Mentha spicata were studied for its antibacterial activity against pathogenic microorganism by disc diffusion method , synthesized AgNPs colloidal solution better antibacterial activity against the pathogen like E.coli, Staphylococcus. The synthesized silver nanoparticles from menthe spicata act against the antifungal activity.
