Glycosides
Herbacetin diglucoside can be isolated from flaxseed hulls.[ 1]
Rhodionin is a herbacetin rhamnoside found in Rhodiola species.[ 2]
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]
