IUPAC 名称
5,7-dihydroxy-2-(4-hydroxyphenyl)-8-[(2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-6-[(2S,3R,4S,5S)-3,4,5-trihydroxyoxan-2-yl]-4H-chromen-4-one
描述
Corymboside, also known as 6-arabinopyranosyl-8-galactopyranosylapigenin, 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. Corymboside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Corymboside can be found in a number of food items such as red bell pepper, carob, common wheat, and orange bell pepper, which makes corymboside a potential biomarker for the consumption of these food products.
