摘要：
The antioxidant behaviour of flavonoids including flavone, flavanol and isoflavone isolated from leaves of Warionia saharae and the related activity-structure relationships were investigated by measuring their abilty to scavenge the free radical 2,2-diphenylpicrylhydrazyl show that the antioxidant activity depends both on substitution of hydroxyl groups of the flavonoids skeleton and the presence of an unsaturation at the C2-C3 bond in conjugation with 4 oxo function.
