Common Name5,7-dihydroxy-2-(4-hydroxyphenyl)-8-[(2s,3r,4r,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-6-[(2s,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]chromen-4-one
DescriptionIsoviolanthin belongs to the class of organic compounds known as flavonoid 8-c-glycosides. Flavonoid 8-C-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to 8-position of a 2-phenylchromen-4-one flavonoid backbone. Thus, isoviolanthin is considered to be a flavonoid. 5,7-dihydroxy-2-(4-hydroxyphenyl)-8-[(2s,3r,4r,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-6-[(2s,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]chromen-4-one is found in Angiopteris evecta and Passiflora sexflora. 5,7-dihydroxy-2-(4-hydroxyphenyl)-8-[(2s,3r,4r,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-6-[(2s,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]chromen-4-one was first documented in 2009 (PMID: 20183252). Based on a literature review a small amount of articles have been published on Isoviolanthin (PMID: 26214885) (PMID: 33238063) (PMID: 29882900) (PMID: 28769988).
