FL: Flavonoid
The word "flavonoid" comes from its Latin origin flavus (yellow) with oid, meaning yellow-ish. It is probably due to its function as (yellow) flower pigments. Chemically speaking, it is a class of plant secondary metabolites that have two benzene rings (each called A-ring and B-ring) connected by a chain of three carbons (Figure 1). The carbon chain, corresponding to the numbers 2,3,4 in Figure 1, is linked to a hydroxyl group in the A-ring to form the C-ring. The class of flavonoids are usually determined by the modification pattern of the C-ring (Table 1). Flavonoid is utilized in many industrial processes from pigments to food additives. Often heard names include anthocyanin, catechin, flavan (tea), and isoflavone. |
フラボノイドの語源は、ラテン語のflavus (黄色)に「~のような」という意味のoidをつけたものです。黄色を含む花の色素がフラボノイドだからかもしれません。 化学的な定義でフラボノイドとは、ベンゼン環2個(それぞれA環B環と呼ばれる)を3つの炭素(C)で結合した、植物の代謝産物の総称です(Figure 1)。 Figure 1において2,3,4と番号付けされた炭素鎖はA環の水酸基と結合してC環を構成します。フラボノイドのカテゴリーはたいていC環の修飾パターンで決まります(Table 1)。
フラボノイドの用途は色素から食品添加物まで多様です。よく耳にするものでは、アントシアニン、カテキン、フラバン(茶)、イソフラボンなど、全てフラボノイドです。 |

Biosynthesis
Flavonoid is synthesized through the phenylpropanoid-acetate pathway in all higher plants. It is responsible for many biological activities including pigments, anti-oxidative or anti-allergic agents, and signaling elements in nodule formation. Some of them are quite familiar in our daily life. |
