Abstract:
In order to find safe natural antioxidant，taking pitaya flower as the research object，with ethanol as extraction solvent，heating reflux extraction of pitaya flower for in vitro antioxidant activity evaluation method，total flavonoids content was determined，antioxidant activity of samples was determined from five aspects,using the method of DPPH，salicylic acid，adjacent phenyl phenol method，ferric thiocyanate method，Prussian blue method,with chemical synthetic fat-soluble antioxidants TBHQ as positive reference substance,the pitaya flower under different concentrations of antioxidant activity of flavonoids was researched.The results showed the pitaya flower flavonoids content was 2.62 mg/mL，removal ability of flavonoids on DPPH ? was similar with TBHQ，IC50 of clearing ?OH was 0.57 mg/mL，IC50 of removing superoxide anion was 1.41 mg/mL，IC50 of inhibiting of lipid peroxidation was 1.80 mg/mL，reducing power was relatively weak.Studies showed that flavonoids pitaya flower had strong antioxidant activity，as the application of natural antioxidants.
