Description; General description; Catechins are phytochemicals, richly present in black grapes, peaches, strawberries and broad beans. Catechins occur in various forms such as catechins, epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate.; Application; (+)-Catechin hydrate has been used: • as a polyphenol standard in the determination of total polyphenols in the by-products of red wine • as an additive to study its effects on in vitro methane production and substrate degradation in a triple-fed batch approach • as a substrate to determine the activity of pure L. plantarum CECT 748T 14 recombinant tannase on catechin; Packaging; 5, 10 g in poly bottle; Biochem/physiol Actions; An antioxidant flavonoid of plant origin; a free radical scavenger, preventing free radical-mediated damage in a variety of biological systems. For example, at physiological pH catechin suppressed DNA strand breaks by hydroxyl radicals. It has also been shown to prevent human plasma oxidation. It delayed the consumption of endogenous lipid-soluble antioxidants and inhibited lipid oxidation.; Features and Benefits; This compound is also offered as part of Sigma′s Library of Pharmacologically Active Compounds (LOPAC®1280), a biologically annotated collection of high-quality, ready-to-screen compounds.
