IUPAC 名称
2-(3,4-dihydroxyphenyl)-8-[2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-4-yl]-4-[2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-6-yl]-3,4-dihydro-2H-1-benzopyran-3,5,7-triol
描述
Arecatannin b1 is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Arecatannin b1 is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Arecatannin b1 can be found in common grape, which makes arecatannin b1 a potential biomarker for the consumption of this food product.
