Chalcones and aurones are called anthochlor (chlōros means yellow in Greek). When flowers with anthochlor are fumed with ammonia, they turn to red. Anthochlors are found in at least Caryophyllaceae, Asteraceae, Rosaceae, and Scrophulariaceae. Aurones are oxidized forms of chalcones and usually both exist together in yellow flowers. Chalcones, unlike aurones, also occur sporadically in other parts of plants. Dihydrochalcones lack the double bond in the C3 chain and do not act as pigments. When chalcones (and their glycosides) are hydrolyzed by acid, the color also disappears because their conversion to flavanones.
No C-glycoside has been found in aurones and auronols. Aurones are found from lower plants too (e.g. Asplenium and Marchantia). Chalcones are sporadically found in Asteraceae and Fabaceae, but in Aristolochiaceae, all genera contain chalcones [1].

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。 |
