Description

3Beta-Methyl-5,7-dihydroxy-8-methoxy-3,4-dihydro-1H-2-benzopyran-1-one belongs to the class of organic compounds known as 2-benzopyrans. These are organic aromatic compounds that 1-benzopyran, a bicyclic compound made up of a benzene ring fused to a pyran, so that the oxygen atom is at the 2-position. 5,7-dihydroxy-O-methylmellein is found in Astrocystis sp. BCC 22166. It was first documented in 2014 (Kornsakulkarn, J., et al.). Based on a literature review very few articles have been published on 3beta-Methyl-5,7-dihydroxy-8-methoxy-3,4-dihydro-1H-2-benzopyran-1-one.
