GENERAL DESCRIPTION & APPLICATION |
||
| Polyphenols are referred to a group of phenolic compounds which have at least two hydroxy groups in one molecules found in plants. At a lower concentration than that of the oxidizable substrate, polyphenols act as primary antioxidants which inhibit or delay the oxidative processes by the donation of an electron or hydrogen atom, resulting in the protection of cells and body before cell damage caused by highly reactive free radicals and atoms. Polyphenols are components of flavonoids, plant pigments, flavours of plants. Polyphenols are taken application of free radical scavenging properties and chelating capacities for anti-aging and cancer prevention. | ||
