Malvidin 3,5-diglucoside
IUPAC 名称
7-hydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-3,5-bis({[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy})-1λ⁴-chromen-1-ylium chloride
描述
Malvidin 3,5-diglucoside, also known as malvin, is a member of the class of compounds known as anthocyanidin-5-o-glycosides. Anthocyanidin-5-o-glycosides are phenolic compounds containing one anthocyanidin moiety which is O-glycosidically linked to a carbohydrate moiety at the C5-position. Malvidin 3,5-diglucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Malvidin 3,5-diglucoside can be found in bilberry, carrot, common bean, and wild carrot, which makes malvidin 3,5-diglucoside a potential biomarker for the consumption of these food products. Malvin reacts in the presence of H2O2 to form malvone. The ortho-benzoyloxyphenylacetic acid esters reaction product is dependant of the pH: it is obtained under acidic conditions whereas under neutral conditions, the reaction product is the 3-O-acyl-glucosyl-5-O-glucosyl-7-hydroxy coumarin .
