Common Name5-hydroxy-2-(3-hydroxy-4-methoxyphenyl)-7-methoxy-3-{[(2s,3r,4s,5s,6r)-3,4,5-trihydroxy-6-({[(2r,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}methyl)oxan-2-yl]oxy}chromen-4-one
DescriptionOmbuoside belongs to the class of organic compounds known as flavonoid-3-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. Thus, ombuoside is considered to be a flavonoid. 5-hydroxy-2-(3-hydroxy-4-methoxyphenyl)-7-methoxy-3-{[(2s,3r,4s,5s,6r)-3,4,5-trihydroxy-6-({[(2r,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}methyl)oxan-2-yl]oxy}chromen-4-one is found in Gynostemma pentaphyllum and Kaempferia parviflora. 5-hydroxy-2-(3-hydroxy-4-methoxyphenyl)-7-methoxy-3-{[(2s,3r,4s,5s,6r)-3,4,5-trihydroxy-6-({[(2r,3r,4r,5r,6s)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}methyl)oxan-2-yl]oxy}chromen-4-one was first documented in 2017 (PMID: 27993866). Based on a literature review a small amount of articles have been published on Ombuoside (PMID: 35163950) (PMID: 34702089) (PMID: 30566585) (PMID: 29734446).
