摘要：

An eco-friendly method for obtaining metallic nanoparticles using Sideritis Scardica plant is presented in our research. The first step was conducted to investigate and compare the composition, total phenolic, flavonoid, tannins and terpenoids contents in flowers and strains of Sideritis Scardica plant. For phytochemicals analyses it was used the UV-VIS Specord M400, using different wavelengths and the results were calculated using standard calibration curves. Antioxidant activity was determined using DPPH method. The infrared spectral analysis was carried out to characterize the type of functional groups existent in different parts of Sideritis Scardica plant (flowers and strains). The second step of this research study was to use a green method for obtaining metallic nanoparticles due to the biomolecules present in plant extracts, which can be used to reduce metal ions to nanoparticles. This study presents the use of Sideritis Scardica flowers and strains for the biosynthesis of metal nanoparticles. The formation and characterization of metal nanoparticles (PtNP, AgNP, Au, NP) in Sideritis Scardica extracts was confirmed by UV-Vis and FTIR spectroscopy, dynamic light scattering (DLS), optical microscopy (OM), atomic force microscopy (AFM) and scanning electron microscopy (SEM).
