Polyphenolic compounds in green tea
The properties of green tea stem primarily from its high content of polyphenolic compounds . Flavonoid content can reach up to 30-36% of the dry weight of the leaves. The most important role is played by catechin compounds (flavanols), which constitute approximately 80% of the flavonoid complex: epigallocatechin gallate, epigallocatechin, epicatechin gallate, and epicatechin.
These compounds are characterized by a very strong antioxidant effect , resulting from the ability to scavenge and limit the production of free radicals, as well as an anti-edema effect, which is valued in cosmetics .
Additionally, in lower concentrations, other flavonoids are also present – kaempferol, rutin, quercetin, myricetin and their glycosides – which have, among other things, antioxidant and platelet aggregation-inhibiting effects .
