Natural Product Identification
Common Name6,7,8-Trihydroxy-5-methoxyflavanone
DescriptionOresbiusin belongs to the class of organic compounds known as 5-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C5 atom of the flavonoid backbone. Thus, oresbiusin is considered to be a flavonoid. 6,7,8-Trihydroxy-5-methoxyflavanone is found in Isodon oresbius. 6,7,8-Trihydroxy-5-methoxyflavanone was first documented in 2010 (PMID: 20423097). Based on a literature review a small amount of articles have been published on Oresbiusin (PMID: 25204149) (PMID: 23947137).
