The word "flavonoid" comes from its Latin origin ''flavus'' (yellow) with ''oid'', meaning yellow-ish.  It comes from its history as yellow natural dye (quercetin and kaempferol are the most widespread flavone dyes. See [[:Category:FL3F|flavone]]).

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).

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。これは代表的なフラボンであるquercetinやkaempferolが広く使われてきた黄色の天然色素であることに由来しています ([[:Category:FL3F|flavone]]参照)。

|Flavonoid is synthesized through both the phenylpropanoid-acetate pathway and the acetate-malonate pathway in all higher plants (but not algae). Most plants contain the 7 major subgroups (chalcones, flavanones, flavones, flavonols, flavans, anthocyanidins, and anthycyanins), but aurones　or isoflavonoids are not ubiquitous.

−
|フラボノイドは全ての高等植物においてフェニルプロパノイド経路および酢酸－マロン酸経路の両方を用いて生成され （海草では異なる）、ほとんどの植物は7つの大きなグループ (カルコン、フラバノン、フラボン、フラボノール、フラバン、アントシアニジン、アントシアニン） を含みます。しかしオーロンやイソフラボノイドは全ての植物に含まれるわけではありません。

にわかれます。 たとえば, 1 では、クマリン, リグナン, リグニンなどが生合成され, 2 の酢酸－マロン酸経路では, アントラキノンが知られています。

フラボノイドは, 上記 2 つの, 脂肪酸フェニルプロパノイド経路と 酢酸-マロン酸パスウェイとの 組み合わせにより生合成されます。 同様のパスウェイから生成される産物には, キサントン, スチルベンなどがあります。

[edit] Class Overview

The word "flavonoid" comes from its Latin origin flavus (yellow), meaning yellow-ish. It comes from its history as yellow natural dye (quercetin and kaempferol are the most widespread flavone dyes. See flavone).

In chemistry terms, 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).

Figure 1: The Backbone of Flavonoid Structure

Flavonoid is utilized in many industrial processes from pigments to food additives. Well known names include anthocyanin, catechin, flavan, and isoflavone.

[edit] Database statistics/ranking

This database collects original references that report identification of flavonoid in various plant species. The database consists of three major namespaces: (flavonoid) compounds, plant species, and references. Currently, 6961 flavonoid structures, 3961 plant species, and 5215 references describing total 19861 metabolite-species relationships are registered.
