Chemical compound

Herbacetin is a flavonol, a type of flavonoid.

Glycosides

Herbacetin diglucoside can be isolated from flaxseed hulls.^[1]

Rhodionin is a herbacetin rhamnoside found in Rhodiola species.^[2]

Other related compounds

Rhodiolin, a flavonolignan, is the product of the oxidative coupling of coniferyl alcohol with the 7,8-dihydroxy grouping of herbacetin. It can be found in the rhizome of Rhodiola rosea.^[3]
