(2S,2'R,3R,3'R)-2,2',3,3'-Tetrahydro-3',5,5',7,7'-pentahydroxy-2-(4-hydroxyphenyl)-2'-(3,4,5-trihydroxyphenyl)-[3,8'-bi-4H-1-benzopyran]-4,4'-dione

Description

GB-4a 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''. (2S,2'R,3R,3'R)-2,2',3,3'-Tetrahydro-3',5,5',7,7'-pentahydroxy-2-(4-hydroxyphenyl)-2'-(3,4,5-trihydroxyphenyl)-[3,8'-bi-4H-1-benzopyran]-4,4'-dione is found in Gnidia involucrata . Based on a literature review very few articles have been published on GB-4a.
