Polyphenol The term polyphenol should be used to define compounds exclusively derived from the shikimate / phenylpropanoid and/or the polyketide pathway, featuring more than one phenolic unit and deprived of nitrogen-based functions.olyphenol oxidase (PPO) is an enzyme that catalyses the oxidation of o-diphenols to produce o-quinones. It is the rapid polymerisation of o-quinones to produce black, brown or red polyphenolic pigments that is the cause of fruit browning.

Part 3 â Suggested foods and supplements Research aimed at finding the active compounds in green tea revealed that its protective effects are due chiefly to catechins. Tea contains four main catechin substances: EC, ECg, EGC and EGCg, all of which are inclusively called catechin. Epigallocatechin gallate (EGCG) is the most powerful of these catechins. EGCG as an antioxidant is about 25-100 times more potent than vitamins C and E. One cup of green tea provides 10-40 mg of polyphenols and has antioxidant effects greater than a serving of broccoli, spinach, carrots, or strawberries.

It is easy to prepare from a number of different sources – bananas are particularly good – and the reaction is readily followed using a colorimeter. Catechol oxidase has a number of alternative names, (Polyphenol oxidase, Diphenol oxidase, Tyrosinase, etc, EC 1.10.3.1 ). The reaction is also catalysed by EC 1.14.18.1 and it is not easy to distinguish between the enzymes.
