Antioxidant properties and quantitative UPLC-MS/MS analysis of phenolic compounds in dandelion (Taraxacum officinale) root extracts
Prolonged exposure to metabolically derived reactive oxygen species (ROS) can cause an imbalance between radical species and in vivo physiological antioxidant defences. As a result, ROS have the potential to bind and irreversibly oxidise nucleic acids, proteins, lipids, carbohydrates and DNA.1 Failure to repair or remove these oxidised molecules may lead to cellular dysfunction and mutation, wh...
متن کاملPolyphenolic compounds and antioxidant properties of selected China wines
Thirty-seven China wines, produced from different geographical origins, were examined in this study. The antioxidant activity of wines was measured by different analytical methods: oxygen radical absorbance capacity (ORAC), reducing power, 2,2-azino-di-(3-ethylbenzothialozine-sulphonic acid) (ABTS), 2,2diphenyl-1-picrylhydrazyl (DPPH ), hydroxyl radical-scavenger activity, superoxide radical-sc...

Total Phenolic Content and Antioxidant Properties of Taraxacum officinale Extracts Obtained with Different Solvents
Total phenolic content and antioxidative properties of Taraxacum officinale leaves and flowers extract was studied. Extracts was made with different solvents: classical organic and surfactant solutions. The results showed that all examined extracts contain some polyphenols and have antioxidant potential against DPPH radical and reducing power (Fe3+ Fe2+). Leaf extracts made with organic solvent...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
