Description

7-Methoxy-8-[2-methoxy-5-(7-methoxy-4-oxo-3,4-dihydro-2H-1-benzopyran-2-yl)phenyl]-2-(4-methoxyphenyl)-3,4-dihydro-2H-1-benzopyran-4-one 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''. 7-methoxy-8-[2-methoxy-5-(7-methoxy-4-oxo-2,3-dihydro-1-benzopyran-2-yl)phenyl]-2-(4-methoxyphenyl)-2,3-dihydro-1-benzopyran-4-one is found in Semecarpus anacardium. Based on a literature review very few articles have been published on 7-methoxy-8-[2-methoxy-5-(7-methoxy-4-oxo-3,4-dihydro-2H-1-benzopyran-2-yl)phenyl]-2-(4-methoxyphenyl)-3,4-dihydro-2H-1-benzopyran-4-one.
