L-Epicatechin CAS 490-46-0, also known as (-)-epicatechin or (2R,3R)-epicatechin, is a naturally occurring polyketide-derived flavonoid and flavanol found abundantly in green tea, cocoa beans, chocolate, grape seeds, and various plant barks. It typically appears as a white to light yellow crystalline powder or solid and is hygroscopic in nature.
Recognized for its potent antioxidant capacity and diverse biological activities, L-Epicatechin plays a significant role in promoting cardiovascular health, scavenging free radicals, mitigating oxidative stress, and supporting metabolic and muscle function.
