Delphinidin 3-xyloside
IUPAC 名称
3-{[(2S,3R,4R,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]oxy}-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)-1lambda4-chromen-1-ylium
描述
Delphinidin 3-xyloside is a member of the class of compounds known as anthocyanidin-3-o-glycosides. Anthocyanidin-3-o-glycosides are phenolic compounds containing one anthocyanidin moiety which is O-glycosidically linked to a carbohydrate moiety at the C3-position. Delphinidin 3-xyloside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Delphinidin 3-xyloside can be found in a number of food items such as black chokeberry, redcurrant, gooseberry, and blackcurrant, which makes delphinidin 3-xyloside a potential biomarker for the consumption of these food products.
