Summary
The flavonoid profile of Capsella bursa-pastoris (L.) Medik. (Brassicaceae) and the antioxidant activity of its methanolic and aqueous extracts were studied. Glycosides of quercetin, chrysoeriol, kaempferol, and isorhamnetin were identified. Chrysoeriol O-glucoside and isorhamnetin O-rutinoside were detected in this species for the first time. The extracts presented an antioxidant activity against DPPH radicals, peroxyl radicals, hydroxyl radicals, and hydrogen peroxide.
Keywords:
