Embodiment 1
[0056] Example 1 Determination of antioxidant activity
[0057] 1. Sample: Quantitative Chinese medicine oil-water two-phase extract + ergothioneine and tocopherol concentration gradient: A1: 0.01%, 0.2%; A2: 0.015%, 0.4%; A3: 0.02%, 0.6%; A4: 0.03%, 0.8%. A5: Blank traditional Chinese medicine oil-water two-phase extract.
[0058] 2. Determination of superoxide radical scavenging rate
[0059]Determination by pyrogallol autoxidation method. Take 4.5mL of 50mmol / L Tris-HCl buffer solution (pH8.2), put it in a 25°C water bath and keep it warm for 20min, add 1mL sample solution (A1-A5) and 0.4mL 25mmol / L pyrogallol solution respectively, mix well React in a water bath at 25°C for 5 min, add 1 mL of 8 mmol / L HCl to terminate the reaction, measure the absorbance (Ax) at 299 nm, and replace the sample with the same volume of distilled water in the blank control group. Calculate the O2- scavenging rate according to the following formula:
