Özet
Bacterial infections are one of the most serious health problems all over the world, which cause need for the discovery of new drug. Since antibiotic resistance is a major threat to both humans and the environment, there is a need for studies on the antimicrobial properties of different forms of traditionally used plants. The seeds of Coriandrum sativum were used to isolate essential oil (EO) and to synthesize silver nanoparticles (C-AgNPs). The synthesized AgNPs were characterized by UV-Visible spectrophotometry, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), X-ray difraction (XRD) and Fourier Tranmission Infrared (FTIR). The major oil constituents were characterized by GC-MS as Linalool (79.12%), Camphor (6.16%), gamma-Terpinene (2.82%) and alpha-Pinene (2.67%). The surface plasmon resonance (SPR) of C-AgNPs at 437 nm was recorded on the UV-Vis spectrometer. The spherical and homogenous of C-AgNPs was presented in SEM images. EDX showed elemental distribution and confirmed C-AgNPs. A characteristic intense peak was at 3.0 keV. The antibacterial activities of the essential oil and AgNPs form of Coriandrum sativum seed against Staphylococcus aureus ATCC 29213 and Escherichia coli ATCC 25922 bacteria were investigated by broth microdilution test. C-AgNPs and essential oil of coriander can be expected to provide future opportunities in nanomedicine and materials science. C-AgNPs can be displayed synergistic antimicrobial effect when used in combination with essential oil.
