Antigout Effects of Plantago asiatica: Xanthine Oxidase Inhibitory Activities Assessed by Electrochemical Biosensing Method

Figure 7

Effects of the representative electron transfer signal blocking activities of isoacteoside and myristic acid on XOD/DCNTs/GCE. (a) In the presence of xanthine with different concentration of isoacteoside. The lines to are XOD/DCNTs/GCE in the presence of 28 μg⋅mL⁻¹ xanthine and 0, 3.6, 7.2, and 10.8 μg⋅mL⁻¹ of isoacteoside, respectively. (b) In the absence and in the presence of different concentrations of isoacteoside. (c) In the presence of xanthine and different concentrations of myristic acid. The lines to are XOD/DCNTs/GCE in the presence of 28 μg⋅mL⁻¹ xanthine and 0, 3.0, 12.0, and 30.0 μg⋅mL⁻¹ myristic acid, respectively. (d) In the absence and presence of myristic acid.
