Antioxidant activities and free radical scavenging of black rice anthocyanin capsule

Producing·OH by Fenton reaction, producing O-2 by pyrogallol in alkaline conditions and phosphomolybdate complex method were used to study free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest and Black rice anthocyanin. The study showed that Black rice anthocyanin capsulest and Black rice anthocyanin can effectively eliminate free radicals, has a good antioxidant activity. And ability of free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest and Black rice anthocyanin were increasing along with its density. The ability of free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest was lower than the ability of free radical scavenging and antioxidant activity of Black rice anthocyanin.
