| 3.5 ml absolute ethanol and 400 ul DPPH solution were added sequentially to 100 ul sample solutions with different concentrations. The mixtures were mixed and the reaction was performed in the dark at 37℃ with constant shaking. The reaction mixtures were centrifuged for 5 min at 3000 rpm and the supernatant was removed. The absorbance at 517 nm was measured with a UV-visible spectrophotometer with the absolute ethanol as blank control. |
