Wogonin is an O-methylated flavone, a flavonoid-like chemical compound which is found in Scutellaria baicalensis.

The glycosides of wogonin are known as wogonosides. For example, oroxindin is a wogonin glucuronide isolated from Oroxylum indicum. It is one of the active ingredients of Sho-Saiko-To, a Japanese herbal supplement.
