1.0 2010-04-08 22:07:08 UTC 2025-11-18 23:01:55 UTC FDB006428 Violanthin Violanthin is a member of the class of compounds known as flavonoid 8-c-glycosides. Flavonoid 8-c-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to 8-position of a 2-phenylchromen-4-one flavonoid backbone. Violanthin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Violanthin can be found in rice, which makes violanthin a potential biomarker for the consumption of this food product.
