Flavonoid Content

Flavonoids (or bioflavonoids) (from the Latin word flavus, which means yellow, their shading in nature) are a class of polyphenolic plant and organism optional metabolites. Synthetically, flavonoids have the general structure of a 15-carbon skeleton, which comprises of two phenyl rings (An and B) and a heterocyclic ring (C).[1] This carbon structure can be truncated C6-C3-C6. As indicated by the IUPAC classification, they can be grouped into:

1.flavonoids or bioflavonoids

2.isoflavonoids, got from 3-phenylchromen-4-one (3-phenyl-1,4-benzopyrone) structure

3.neoflavonoids, got from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure

The three flavonoid classes above are all ketone-containing mixes and all things considered, anthoxanthins (flavones and flavonols).[1] This class was the first to be named bioflavonoids. The terms flavonoid and bioflavonoid have additionally been all the more approximately used to depict non-ketone polyhydroxy polyphenol mixes, which are all the more explicitly named flavanoids. The three cycles or heterocycles in the flavonoid spine are for the most part called ring A, B, and C. Ring A generally shows a phloroglucinol replacement design.
