IUPAC 名称
[(3R,4S,6S)-3,4-dihydroxy-6-{[5-hydroxy-2-(4-hydroxyphenyl)-4-oxo-7-{[(2S,4S,5S)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-4H-chromen-3-yl]oxy}-5-{[(2S,4S,5S)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-2-yl]methyl acetate
描述
Kaempferol 3-glucosyl-(1->2)-(6''-acetylgalactoside)-7-glucoside 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. Thus, kaempferol 3-glucosyl-(1->2)-(6''-acetylgalactoside)-7-glucoside is considered to be a flavonoid lipid molecule. Kaempferol 3-glucosyl-(1->2)-(6''-acetylgalactoside)-7-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Kaempferol 3-glucosyl-(1->2)-(6''-acetylgalactoside)-7-glucoside can be found in fenugreek, which makes kaempferol 3-glucosyl-(1->2)-(6''-acetylgalactoside)-7-glucoside a potential biomarker for the consumption of this food product.
