Abstract:
Flavonoids extracted from roots, stems and leaves of wild Rosa roxburghii Tratt by ultrasonic method were used as materials to compare the scavenging ability of DPPH free radical, ABTS free radical, hydroxyl free radical and superoxide anion free radical, so as to provide some reference for the further development of Rosa roxburghii Tratt.The results showed that the scavenging rates of DPPH free radical by flavonoids from roots, stems and leaves of Rosa roxburghii Tratt were 11.3%, 5.2% and 66.9% respectively.The scavenging rates of ABTS were 61.1%, 28.9% and 89.3% respectively.The scavenging rates of hydroxyl radical were 58.1%, 19.3% and 81.5% respectively.The scavenging rates of superoxide free radical were 48%, 42% and 50% respectively.The order of scavenging ability was flavonoids in Rosa roxburghii Tratt leaves>flavonoids in roots>flavonoids in stems.The results showed that the flavonoids from roots, stems and leaves of Rosa roxburghii  Tratt could be developed as natural antioxidants, especially the flavonoids from leaves of Rosa roxburghii Tratt.
