Upper classes : FL Flavonoid : FL7 Anthocyani(di)n

3-Deoxyanthocyanin is the only flavonoid in Azolla species (floating ferns). Its reddish color comes from this flavonoid. Palatability of Azolla by snails and tadpoles (and probably fish) is known to negatively correlate with frond deoxyanthocyanin levels[1] Apigeninidin and luteolinidin are known as red pigments of Sorghum vulgare, a grain sorghum cultivar.

Major Plant Families

The number in each family is counted as the number of genera (not species) listed in our registered references. Each reference record is accessible by clicking the link in compound pages. The taxonomy follows the APG-II classification. For details (or if the figure is broken), visit this page.

Patterns of Hydroxylation

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.
