Violanthin
IUPAC 名称
5,7-dihydroxy-2-(4-hydroxyphenyl)-6-[(2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-8-[(2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]-4H-chromen-4-one
描述
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.
