Flavones

Abstract

The number of naturally occurring flavones known at present is 128, excluding flavonols and glycosides of both flavones and flavonols which are treated in Chapters 7 and 8. The parent unsubstituted flavone, produced apparently by an aberrant biosynthetic pathway, occurs in the farina on species of Primula and the closely related Dionysia (Harborne, 1971). 2’-Hydroxyflavone and 5, 2′-dihydroxy-flavone have very recently been detected in the secretion of the glandular cells of Primula florindae flowers (Bouillant et al, 1971a). The 95 flavones in the following six tables (Tables 6.1–6.6) are derived from 32 hydroxyflavones, only eighteen of which have been isolated so far; the remaining fourteen occur as partially or fully O-methylated products. Thus no hexa- or heptahydroxyflavone has yet been isolated, although nine ethers of 5, 7, 8, 2′, 3′, 4′- and 5, 6, 7, 8, 3′, 4′-hexahydroxyflavone and four ethers of 5, 6, 7, 8, 3′, 4′, 5′-heptahydroxyflavone are known. Linderoflavones A and B are the only two flavones containing a methylenedioxy group. The letters A and G in the second column of Tables 6.1–6.6 signify occurrence as the aglycone and as a glycoside respectively.
