The aim of this research is to study the chemical components cinnamon, rosemary, and clove volatile oils by GC/Mass as well antioxidant activity these their mixture DPPH scavenging select best oil or for preparing beef sausage treated with laser rays (Helium-Neon wavelength 632.8 nm 9 min each side). Also, effect at 500 ppm radiation on lipid oxidation shelf-life during cold storage. Results in...

The exposure of human cells to oxidative stress leads to the oxidation of biomolecules such as lipids, proteins and nuclei acids. In this study, the oxidation of lipids, proteins and DNA was studied after the addition of hydrogen peroxide and Fenton reagent to cell suspension containing human leukemic monocyte lymphoma cell line U937. EPR spin-trapping data showed that the addition of hydrogen ...

Investigations were performed on the influence of resveratrol on the lipid composition, metabolism, fatty acid and peroxide level in plasma membranes of hepatocytes, isolated from aged rats. Hepatocytes were chosen due to the central role of the liver in lipid metabolism and homeostasis. The obtained results showed that the level of sphingomyelin (SM) and phosphatidylserine (PS) was augmented i...

with regard to the importance of antioxidants in foods, cosmetics and pharmaceutics, there are several studies on natural resources for finding rich sources of antioxidants and their role in protecting the body against oxidative stress injuries. the purpose of this study was to investigate the antioxidant stability of arbutin and the pyrus boissieriana buhse leaf extract and their effects on li...

Oxidation of fats and oils is an important indicator for performance and shelf life of oils. As other vegetable oils, virgin coconut oil (VCO) is not susceptible to lipid oxidation. Thus, a rapid method for quantitative analysis of peroxide value in VCO was developed in this study using Fourier transform infrared (FTIR) spectroscopy coupled with attenuated total reflectance (ATR). Thirty traini...

1. Homogenates of rat liver, spleen, heart and kidney form lipid peroxides when incubated in vitro and actively catalyse peroxide formation in emulsions of linoleic acid or linolenic acid. 2. In liver, catalytic activity is distributed throughout the nuclear, mitochondrial and microsomal fractions and is present in the 100000g supernatant. Activity is weak in the nuclear fraction. 3. Dilute (0....

compounds derived from lipid oxidation endangering human health and lead to cardiovascular disease and cancer. the addition of antioxidants is effective in retarding the oxidation of lipids and lipid containing foods. due to the toxicological effects of synthetic antioxidants, decrease their use and replacing them with natural antioxidants. this study investigates antioxidant effect of pimpinel...

abstract in recent years some research results have appeared that exogenous salicylic acid provided significant mitigation effect against salinity induced injuries in plants. an experiment was conducted to investigate the effects of salt stress and salicylic acid on radish (raphanus sativus l.) plants. after appearing first leaves, plants were treated by salicylic acid (0.2 mm) for 3 days and n...
