Flavonoid Top

Molecule Index

Upper classes : FL Flavonoid : FL3 Flavone

The basic structure of flavone is 2-phenylbenzopyrone, the same as flavonol. The word 'flavone' first appeard in 1895^[1], indicating its yellow color. luteolin, quercetin, kaempferol were widespread natural dyes before synthetic dyes were invented in 1856 ^[2]. Chrysin was the first flavone to be isolated in a pure form. Many members in Asteraceae contain unique flavones, especially the genus Cirsium and Onopordum in the tribe Cardueae (or equivalently, Cynareae), commonly known as thistles.

Structure

Flavones are commonly present in vacuoles as O- and/or C-glycosides. Most glycosides are 7-, 3'-, and 4'-glycosides. 5-glycoside is rare because the 5-hydroxyl group forms a hydrogen bond with the adjacent 4-carbonyl group. Flavone glycosides have been frequently used as chemotaxonomic markers^[3].
Isovitexin (C-glycosylflavone) acts as co-pigments of anthocyanins in Iris ensata Thunb. (Japanese iris flower)^[4]

The 5th and 6th digits of our flavonoid ID indicates the hydroxylation patterns of A-ring and B-ring (See the upper-right figure. The leftmost ring is A, rightmost is B), respectively. The following chart is spanned by these 2 digits. R indicates H or CH₃, and R' indicates H or R. Numbers are IUPAC positions. The value in each cell (such as GS: glycosilation only) corresponds to the 7th and 8th digits, which is explained at the bottom of this page.
