Kaempferide is an O-methylated flavonol, a type of chemical compound. It can be found in Kaempferia galanga (aromatic ginger).

Metabolism

The enzyme kaempferol 4'-O-methyltransferase uses S-adenosyl-L-methionine and kaempferol to produce S-adenosyl-L-homocysteine and kaempferide.

Icariin is the tert-amyl alcohol derivative of kaempferide 3,7-O-diglycoside.
