Low-level Free Phenols in Sicilian Olive Oils

2010
Publisher Summary The phenolic fraction of olive oils can be analyzed in different manners: the simple total quantitative determination is carried out by a colorimetric method, and the single phenols qualitative and quantitative analysis by using chromatographic or electrophoretic methods.

Free phenolic compounds in waters of the Ross Sea

Science of The Total Environment, 2019
The presence of free phenolic compounds (PC) in Antarctic sea water has been investigated to explain their source and particle size distribution in the atmospheric aerosols, as determined in our previous research. The sea water samples were filtered to distinguish the PC concentrations in the particulate and dissolved fractions.

Free phenols in chronic renal failure.

Clinical nephrology, 1976
Serum total free phenols are elevated in chronic renal failure, acute renal failure and hepatic coma. Being partly protein-bound, phenols behave during dialysis in a similar manner to considerably larger molecules which are not protein-bound. In view of their potential toxicity they should be considered as an alternative to 'middle molecules'. Patients

Free radical scavenging and cytoprotective activities of phenolic antioxidants

Molecular Nutrition & Food Research, 2006
AbstractThe free radical scavenging activities of three flavonoids (quercetin, rutin and catechin) and four hydroxycinnamic acids (caffeic, ferulic, sinapic, and chlorogenic acids) were evaluated using both oxygen radical absorbance capacity (ORAC) and lipid peroxidation inhibition capacity (LPIC) assays.

Gas-Free Phenolic Resin for Friction Materials

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">Phenolic resins have been widely used as a binder for friction materials such as disk pads and brake linings. Requirements for disk pads are flexibility, heat resistance, low wear and so on.</div> <div class="htmlview paragraph">To solve the above requirements, we have developed various modified resins.
