*2.5.3 Biosynthesis of flavonoids and condensed tannins*

In the process of flavonoid biosynthesis, the identification and isolation of genes by the flavonoids which are a colored compound. Mutant phenotypes are identifiable from variation in color easily. The flavanonols can converted to anthocyanins. Condensed tannins transformed from polymerization of flavonoids [8, 11].
