IUPAC 名称
6-[(2S,3R,4S,5S,6R)-4,5-dihydroxy-6-(hydroxymethyl)-3-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-2-yl]-5,7-dihydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one
描述
Meloside, also known as isovitexin 2''-beta-D-O-glucoside or 2'-O-beta-D-glucosylisovitexin, is a member of the class of compounds known as flavonoid c-glycosides. Flavonoid c-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to the 2-phenylchromen-4-one flavonoid backbone. Meloside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Meloside can be found in muskmelon, which makes meloside a potential biomarker for the consumption of this food product.
