Infobox references

Sakuranetin is a flavanone, a type of flavonoid. It can be found in Polymnia fruticosa^[1] and rice, where it acts as a phytoalexin against spore germination of Pyricularia oryzae.^[2]

Glycosides

Sakuranin is the -O-glucoside of sakuranetin.

Metabolism

biosynthesis

Naringenin 7-O-methyltransferase uses naringenin to yield sakuranetin, with S-adenosyl-methionine as the methyl donor.^[3]

biodegradation

In compounds like 7-methoxylated flavanones like sakuranetin, demethylation followed by sulfation occur in model organism Cunninghamella elegans.^[4]
