Notes: The catechins, including (−)-epicatechin (EC) and (−)-epigallocatechin gallate (EGCG) (Item No. 70935), are polyphenols which are abundant in green and black teas. (−)-Epicatechin gallate (ECG) is a natural catechin with a single galloyl group. Like EGCG, it inhibits the growth of cancer cells and has anti-inflammatory effects.{23119,23117,23118} The hydroxyl groups of ECG contribute to its potent antioxidant activity and facilitate the killing of methicillin-resistant strains of S. aureus.{23115,23120}
