Diarylheptanoids consist of two aromatic rings (aryl groups) joined by a seven carbons chain (heptane) and having various substituents. They can be classified into linear (curcuminoids) and cyclic diarylheptanoids. The best known member is curcumin, which is isolated from turmeric (''Curcuma longa'') and is known as food coloring E100. Some other ''Curcuma'' species, such as ''Curcuma comosa'' also produce diarylheptanoids. They have been reported from plant in 10 different families, e.g. ''Betulaceae'' and ''Zingiberaceae''. A diarylheptanoid is an intermediate in the biosynthesis of phenylphenalenones in ''Anigozanthos preissii'' or ''Wachendorfia thyrsiflora'' (Haemodoraceae). == Cyclic diarylheptanoids == Cyclic diarylheptanoids formed from myricanone can be isolated from the bark of ''Myrica rubra'' (Myricaceae). Two cyclic diarylheptanoids, named ostryopsitrienol and ostryopsitriol, can be isolated from the stems of endemic Chinese medicinal plant ''Ostryopsis nobilis'' (Betulaceae). Acerogenin M can be found in ''Acer nikoense'' (Sapindaceae). Jugcathayenoside and (+)-galeon can be found in the root bark of ''Juglans cathayensis'' (Juglandaceae). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diarylheptanoid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
