Common NameDemethoxycurcumin
Description(1E,4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-1,4,6-trien-3-one belongs to the class of organic compounds known as curcuminoids. These are aromatic compounds containing a curcumin moiety, which is composed of two aryl buten-2-one (feruloyl) chromophores joined by a methylene group. Demethoxycurcumin is found in Alpinia galanga, Curcuma aromatica , Curcuma mangga , Curcuma xanthorrhiza , Curcuma zedoaria , Etlingera elatior and Zingiber officinale . It was first documented in 2005 (L.Péret-Almeida et al.). Based on a literature review very few articles have been published on (1E,4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-1,4,6-trien-3-one.
