flavonoids

Anthocyanins are a class of natural pigments that are easily soluble in polar solvents and belong to flavonoids. They widely exist in the roots, stems, leaves, flowers and fruits of plants, giving them different colors from red to purple, and are the main coloring substances in plants.

Chalcone isomerase (CHI) is the first recognized enzyme involved in the synthesis of flavonoids and is one of the key enzymes in the flavonoid metabolic pathway. Together with chalcone synthase, it constitutes the rate-limiting enzyme for the biosynthesis of flavonoids.
