Overview
Not only Asteraceae and Fabaceae but also Lamiaceae and Rutaceae contain many flavanones. Aglycones occur as free state in bark, roots and root barks. In ferns, aglycones exist as farinose exudates of fronds. Two flavanone glycosides were also isolated from a liverwort Riccia. Butrin, glucoside of Butin, was the first flavanone identified in nature by Lal and Dutt (1935).

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. 各科のカウントは種名でなく文献に記載された属名の数です。文献は代謝物ページのリンクからたどれ、分類はAPG-IIです。左の図が表示されない場合はここをクリックしてください。 |

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.
