Metabolite Identification
Common NameApigenin 7-arabinoside
DescriptionApigenin 7-arabinoside is a member of the class of compounds known as flavonoid-7-o-glycosides. Flavonoid-7-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Apigenin 7-arabinoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Apigenin 7-arabinoside can be found in chicory, which makes apigenin 7-arabinoside a potential biomarker for the consumption of this food product.
