Test example 2 antioxidant efficacy study-DPPH free radical scavenging experiment
Taking 1g of samples of examples 1-13 and comparative examples 1-4, adding 2mL of absolute ethyl alcohol, adding 2mL of 60 mu mol/L DPPH solution after complete dissolution, mixing uniformly, standing for 30min, zeroing by absolute ethyl alcohol, measuring absorbance at 517nm as Ai, mixing 2mL of absolute ethyl alcohol solvent and 2mL of DPPH solution uniformly to measure absorbance as Ac, dissolving 1g of composition matrix, adding 2mL of absolute ethyl alcohol solvent, mixing uniformly, and measuring absorbance as Aj.
The radical scavenging rate was calculated as follows.
Clearance (%) = [1- (Ai-Aj)/Ac ] ×100%
Wherein, the Aj reaction sample itself contributes to absorbance, the Ai sample acts on the absorbance value after DPPH, and Ac is the absorption of DPPH itself at the measurement wavelength.
The DPPH free radical scavenging rate reflects the antioxidant capacity to a certain extent, and the higher the scavenging rate is, the better the antioxidant degree is, and the better the anti-aging effect is, so the anti-aging effect can be judged through the research of the DPPH free radical scavenging capacity of the composition. The results are shown in table 3 (5 replicates per group of samples, data presented as average).
