''p''-Coumaroylated anthocyanins are a type of anthocyanins with a p-coumaric acid unit linked with a sugar to an anthocyanidin aglycone. 3-(6-''p''-Coumaroyl)glucosides are found in grape and wine. Cyanidin-3-O-(di-p-coumarylglucoside)-5-glucoside is found in dark opal basil. Red leaves of ''Perilla frutescens'' also accumulate cyanidin 3-(6-O-p-coumaroyl-β- D-glucoside)-5-(6-O-malonyl-β-D-glucoside).〔Purification and characterization of anthocyanin 3-aromatic acyltransferase from Perilla frutescens. Fujiwara H, Tanaka Y, Fukui Y, Ashikari T, Yamaguchi M and Kusumi T, Plant Science, 1998, vol. 137, no1, pages 87-94, 〕 Delphinidin 3-(6-''p''-coumaroyl)glucoside is formed by the enzyme anthocyanin 3-O-glucoside 6''-O-hydroxycinnamoyltransferase from delphinidin 3-''O''-glucoside and ''p''-coumaroyl-CoA in the anthocyanin biosynthesis pathway.〔(Delphinidin 3-(6-p-coumaroyl)glucoside synthesis reaction on www.kegg.jp )〕 Red-berries vines of the Pinot varieties are known to not synthesize acetylated or para-coumaroylated anthocyanins, as other grape varietals do, only glucosylated anthocyanins.〔Biosynthesis of Anthocyanins and Their Regulation in Colored Grapes. Fei He, Lin Mu, Guo-Liang Yan, Na-Na Liang, Qiu-Hong Pan, Jun Wang, Malcolm J. Reeves and Chang-Qing Duan, Molecules, 2010, 15, pages 9057-9091, 〕 Anthocyanin 5-aromatic acyltransferase is an enzyme that uses hydroxycinnamoyl-CoA and anthocyanidin-3,5-diglucoside to produce CoA and anthocyanidin 3-glucoside-5-hydroxycinnamoylglucoside. This enzyme can be found in ''Gentiana triflora''. == See also == * Phenolic content in wine 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「P-Coumaroylated anthocyanin」の詳細全文を読む スポンサード リンク
