Study on antioxidant activity of Calligonum beverage

A preliminary study on Calligonum beverage antioxidant activity with chemical model system was carried out. DPPH method, FRAP method, Folin-Ciocalteus method were used to determine the DPPH· radical scavenging, total antioxidant activity and total phenol content of Calligonum beverage respectively. The results showed that DPPH· radical scavenging rate was 36.10% and the antioxidant capacity at this time is equivalent to 152 mg/L of BHT with 40 times dilution of the sample. when diluted for 20 times, the total antioxidant capacity is equivalent to 94.22µmol/L of FeSO4 and the total phenol content is equivalent to 14.93 µ g/L of gallic acid. Calligonum Beverage, therefore, a strong antioxidant beverage, has a broad development prospect.
