Chemical Properties white to light yellow crystal powde Uses Potent antioxidant and antineoplastic agent. Uses Catechin is a polyphenolic flavonoid that has been isolated from a variety of natural sources including tea leaves, grape seeds, and the wood and bark of trees such as acacia and mahogany. Catechin is a more potent antioxidant than ascorbate or α-tocopherol in certain in vitro lipid peroxidation assays. ( )-Epicatechin is a 2R,3R stereoisomer of catechin. Like catechin, ( )-epicatechin is a powerful antioxidant. It inhibits cyclooxygenase 1 (IC50 = 3.2 μM). Also, at 100 μM, ( )-epicatechin induces apoptosis in human adenocarcinoma PC-9 cells and stimulates the inhibition of tumor necrosis factor-α release from BALB-c/3T3 cells treated with epigallocatechin gallate. Uses An antioxidant and natural product from green tea Definition ChEBI: A catechin with (2R,3R)-configuration. General Description ( )-Epicatechin (EC) belongs to the group of flavanols and is abundantly present in cacao and cacao products. The chemical structure of EC includes an oxygenated heterocycle with a 4-hydroxyl group linked with two aromatic rings. Biochem/physiol Actions This antioxidant is found in chocolate. (-)-Epicatechin is linked with cardiovascular effects. It is considered as a dependable standard due to its availability in cacao seeds and cocoa products. The halogenating activity of myeloperoxidase can be restored by (-)-epicatechin.   L-Epicatechin Preparation Products And Raw materials Preparation Products Procyanidin B1
