Antimicrobial Activity of Silver Nanoparticles Synthesis by Green Method from Artemisia Monosperma
Orient J Chem ;34 3. The synthesis of silver nanoparticles by green method is preferred due to less expensive and and could suitable for large scale of synthesis nanoparticles.
Many plant extract can use for synthesis nanoparticale as posses many antioxidant which act as reducing agent Plant extracts possess many antioxidants, which act as reducing agents . Genus Artemisia family asteraceae, comprises about species distributed over all world the genus represented by five species in northern region Saudi Arabia A. Studied was aimed to use the medicinal plant Artemisia monosperma for green synthesis of nanoparticle and study the antimicrobial activity of synthesis nanoparticles against gram positive and gram- negative bacteria.
Fresh plant Artemisia monosperma were collected in spring year from Tabok, North region in Saudi Arabia, and identified in Biology department, faculty of science, Northern Border University, the sample were kept in Herbarium of faculty of science girl section. Synthesis of the AgNPs, take 0.
Bioactive constituents of Artemisia monosperma.
Infrared spectroscopy were monospermaa on a perkin-Elemer fourier transforms inferared spectrometer, silver nanoparticles was centrifuge at Compounds identified by comparison of their retention indices RIC9 to C24 n-alkane mixture and mass spectra with those reported in the literature .

As shown in figure 2, UV —vis spectra showed that in the range of low amounts of the leaf extract monoeperma. The appearance of the above SPR peak at nm, along with absence of nm absorption band indicate of the successful synthesis of AgNPs under experimental conditions.
Bioactive constituents of Artemisia monosperma.
Color change of Ag NPs synthesis from Artemisia monosperma. FTIR spectrum was used to identify the possible function groups of biomolecules in the plant extract that might be responsible for bioreduction and coating of AgNPs. The spectrum of the FTIR spectra of plant extract showed a broad band at cm This band attributed to the OH groups in the biomolecules.
The IR bands at and cm -1 due to C—H stretching vibration modes in hydrocarbon chains. In the case of Ag NPs, a large shift in atemisia absorbance peak with decreased band intensity was observed from The spectra also illustrate xrtemisia prominent shift in the wave numbers corresponding to amide The formation of nanopaerticles was confirmed by TEM Transsimision electron microscopythe image of TEM of silver NPs depicted in figure 3, indicate the shape, morphology and size of synthesis AgNPs, the size was in the range of 18 nm, and monsperma shape was spherical and irregular.
The results of the antibacterial evaluation are presented in table 1. The most susceptible bacteria was Satphylococcus aureus. The antimicrobial activity of silver is well known. In its nanometric form, this characteristic is accentuated.
Due to their size, AgNPs can enter cells and inhibit enzymatic systems in the respiratory chain of some bacteria and thereby alter their DNA synthesis.
The antimicrobial activity of the prepared nanoparticles were studied and the activity was found to depend on the concentration of nanoparticles and their sizes. This work presented synthesis consisting of a reduction of the silver ions using a Artemisia monosperma extract for the first time. The silver, nanoparticles synthesis were confirmed using different techniques. In present study, antimicrobial of synthesized AgNPs by green methods from aqueous extract of plant A.
GC-MS of plant extract shown many important flavonoid Kumatakeninalkaloid Aspidospermidinol and other organic compounds methyl-jasmonate and verbenol.
