PEONIN CHLORIDE(SH)

Peonidin 3,5-diglucoside

C28H33ClO16 (660.1457)

Peonidin 3,5-diglucoside 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. Peonidin 3,5-diglucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Peonidin 3,5-diglucoside can be found in chives, common grape, pineapple, and sea-buckthornberry, which makes peonidin 3,5-diglucoside a potential biomarker for the consumption of these food products.
