What do flavonoids do for plants?
Flavonoids are structurally diverse secondary metabolites in plants, with a multitude of functions. These span from functions in regulating plant development, pigmentation, and UV protection, to an array of roles in defence and signalling between plants and microorganisms.
Are catechins flavonoids?
Catechins are natural polyphenolic compounds—flavan-3-ols (or flavanols), belonging to the flavonoid family. They are found in abundant concentrations in a variety of fruits, vegetables and plant-based beverages. The name catechin is derived from Cutch tree (Acacia catechu L.f.) [1].
What are the health benefits of proanthocyanidins?
