Effect of secondary metabolite compounds of Dracocephalum kotschyi Boiss plant ongreen synthesis of Cu nanoparticles

Medicinal plants are a rich source of secondary metabolites. in the present study, the driedaerial parts of dracocephalum kotschyi boiss were extracted using the digestion method. coppernanoparticles were synthesized by combining the extract with a copper chloride solution at aratio of 1:4. the characteristics of copper nanoparticles were analyzed using various techniquesincluding ultraviolet-visible spectrometry (uv-vis), x-ray diffraction (xrd), scanning electronmicroscopy (sem), energy dispersive x-ray spectroscopy (eds), brunauer-emmett-teller (bet),and fourier transform infrared spectroscopy (ft-ir). the sem analysis predicted the size of thecopper nanoparticles to be 63.28 nm. the eds spectrum confirmed the presence of coppernanoparticles. bet analysis predicted the mesoporous structure of copper nanoparticles.thirty-one (31) compounds were identified in the essential oil of the plant, constituting 93.1%of the total composition. the eight major compounds were perilla acetate (49.3%), 2-methyl-1-octen-3-yne (17.2%), limonene (15.0%), 1,8-cineole (5.2%), trans-α-ocimene (2.4%), p-mentha-1(7),8(10)-dien-9-ol (1.1%), sabinene (1.4%), and 4-terpineol (1.5%).
