L-Epicatechin Chemical Properties,Uses,Production

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.

Definition

ChEBI: A catechin with (2R,3R)-configuration.
