Example Embodiment
[0033] Example 1
[0034] This embodiment provides a method for detecting the antioxidant activity of a traditional Chinese medicine preparation for promoting blood circulation and removing blood stasis.
[0035] Take 0.5g of the content of Xuefu Zhuyu Capsule powder, accurately weigh it, place it in a 25mL volumetric flask, dilute to the mark with 50% v / v methanol, sonicate for 10min, shake well, centrifuge at 14000rpm for 10min, take the supernatant , And then diluted with 50% v / v methanol to 2.00 mg / mL as a sample solution for use.
[0036] Take 25.00mg of DPPH reagent, accurately weigh it, place it in a 250mL brown volumetric flask, dissolve it with pure methanol, and dilute to the mark, shake it up, and then obtain the DPPH methanol working solution.
[0037] Take 50μL of the sample solution and add it to 3 parallel wells of a 96-well cell culture plate, and add 150μL of DPPH methanol working solution as the solution to be tested.
[0038] Take 50 μL of the sample solution and add...
