Sakuranetin is a flavan-on, the 7-methoxy derivative of naringenin, found in Polymnia fruticosa[1] and rice, where it acts as a phytoalexin against spore germination of Pyricularia oryzae.[2]

Glycosides

[edit]

Sakuranin is the 5-O-glucoside of sakuranetin.[citation needed]

Metabolism

[edit]
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]
