Common Name

(2s,3s)-3-[(2s,3s)-2-(2,4-dihydroxyphenyl)-5,7-dihydroxy-4-oxo-2,3-dihydro-1-benzopyran-3-yl]-5,7-dihydroxy-2-(4-hydroxyphenyl)-2,3-dihydro-1-benzopyran-4-one

Description

5,5',7,7'-Tetrahydroxy-2-(2,4-dihydroxyphenyl)-2'-(4-hydroxyphenyl)-3,3'-bi[(2S,3S)-2,3-dihydro-4H-1-benzopyran]-4,4'-dione belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These 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''. Based on a literature review very few articles have been published on 5,5',7,7'-Tetrahydroxy-2-(2,4-dihydroxyphenyl)-2'-(4-hydroxyphenyl)-3,3'-bi[(2S,3S)-2,3-dihydro-4H-1-benzopyran]-4,4'-dione.
