Isappears with acceptance of an electron in the antioxidant sample. All tested samples were dissolved in ethanol. 100 L of DPPH in ethanol was added into a 96-well plate, and was mixed using the test samples (one hundred L) at different concentrations. Right after shaken for 60 s in microplate reader, it was left in the dark at 37 for 30 min. The absorbance was then measured at 515 nm using a microplate reader (BIO-RAD, model 680). All experiments had been carried out in triplicate. Ethanol was applied because the blank control and vitamin C served as constructive control [30,31]. The DPPH radical scavenging activity of the extracts or compounds were calculated in accordance with the following formula. ?? DPPHscavenging activity ?ODblank -ODsample =ODblank ?Statistical analysisAll statistical analyses were performed utilizing SPSS 10.0, as well as the data have been analyzed making use of one-way ANOVA. The imply separations had been performed employing the least important difference approach. Every single experiment was performed in triplicate, and all experiments had been run thrice and yielded related results. Measurements from all the replicates have been combined, along with the therapy effects have been analyzed.Luo et al.
