  • biomimetic synthesis of silver nanoparticles by aqueous extract of Syzygium aromaticum
    Materials Letters, 2012
    Co-Authors: K Vijayaraghavan, S Kamala P Nalini, N Udaya K Prakash, D Madhankumar
    Abstract:

    Abstract The present investigation deals with the synthesis of silver nanoparticles (AgNPs) by green synthesis that has advantages over conventional methods involving chemical agents associated with environmental toxicity. Green synthesis method involves the use of Syzygium aromaticum extract in the universal solvent namely water. The reaction process was simple and convenient to handle, and was monitored using ultraviolet–visible spectroscopy (UV–vis). The results were promising and rapid in the production of silver nanoparticle with a surface plasmon resonance occurring at 430 nm. The formed nanoparticles ranged in dimension between 20 and 149 nm which was almost spherical in shape. EDAX confirmed that the formed nanoparticles are silver as the optical absorption peak was observed approximately at 3 keV, which is typical for the absorption of metallic silver nanocrystallites.

  • the antioxidant content and protective effect of argan oil and Syzygium aromaticum essential oil in hydrogen peroxide induced biochemical and histological changes
    International Journal of Molecular Sciences, 2018

    Abstract:

    Oxidative stress is an important etiology of chronic diseases and many studies have shown that natural products might alleviate oxidative stress-induced pathogenesis. The study aims to evaluate the effect of Argan oil and Syzygium aromaticum essential oil on hydrogen peroxide (H2O2)-induced liver, brain and kidney tissue toxicity as well as biochemical changes in wistar rats. The antioxidant content of Argan oil and Syzygium aromaticum essential oil was studied with the use of gas chromatography. The animals received daily by gavage, for 21 days, either distilled water, Syzygium aromaticum essential oil, Argan oil, H2O2 alone, H2O2 and Syzygium aromaticum essential oil, or H2O2 and Argan oil. Blood samples were withdrawn on day 21 for the biochemical blood tests, and the kidney, liver and brain tissue samples were prepared for histopathology examination. The results showed that the content of antioxidant compounds in Syzygium aromaticum essential oil is higher than that found in Argan oil. H2O2 increased level of blood urea, liver enzymes, total cholesterol, Low Density Lipoprotein (LDL-C), Triglycerides (TG) and Very Low Density Lipoprotein (VLDL), and decreased the total protein, albumin and High Density Lipoprotein-cholesterol (HDL-C). There was no significant effect on blood electrolyte or serum creatinine. The histopathology examination demonstrated that H2O2 induces dilatation in the central vein, inflammation and binucleation in the liver, congestion and hemorrhage in the brain, and congestion in the kidney. The H2O2-induced histopathological and biochemical changes have been significantly alleviated by Syzygium aromaticum essential oil or Argan oil. It is concluded that the Argan oil and especially the mixture of Argan oil with Syzygium aromaticum essential oil can reduce the oxidative damage caused by H2O2, and this will pave the way to investigate the protective effects of these natural substances in the diseases attributed to the high oxidative stress.
