Vitexin 6''-O-malonyl 2''-O-xyloside
IUPAC 名称
5,7-dihydroxy-2-(4-hydroxyphenyl)-8-[(2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-4H-chromen-4-one
描述
Vitexin 6''-o-malonyl 2''-o-xyloside, also known as apigenin 8-C-glucoside or 8-glycosyl-apigenin, 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. Vitexin 6''-o-malonyl 2''-o-xyloside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Vitexin 6''-o-malonyl 2''-o-xyloside can be synthesized from apigenin. Vitexin 6''-o-malonyl 2''-o-xyloside is also a parent compound for other transformation products, including but not limited to, vitexin 2''-O-beta-L-rhamnoside, 7-O-methylvitexin 2''-O-beta-L-rhamnoside, and vitexin 2''-O-beta-D-glucoside. Vitexin 6''-o-malonyl 2''-o-xyloside can be found in common beet, which makes vitexin 6''-o-malonyl 2''-o-xyloside a potential biomarker for the consumption of this food product.
