Peroxyl radical (ROO•) scavenging activity of ULH-002. Peroxyl radical scavenging activity of ULH-002 solutions was measured with the oxygen radical absorbance capacity (ORAC) assay. (A), standard curve of the ORAC assay. (B), ULH-002 solutions were prepared at different concentrations and left at the room temperature for one week. The control solutions were freshly prepared at the same concentrations. Both one-week-old (1 w) and fresh solutions (Fresh) were reacted with fluorescein and AAPH solutions. Histograms represent the average ORAC capacity of each solution from three independent experiments. Data were expressed as the mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001 vs. “0”. (C), time courses of the reaction of fluorescein (FL) with AAPH in the presence of trolox at different concentrations. (D), time courses of the reaction of FL with AAPH in the presence of different samples. 1 w-0.1, one week old ULH-002 solution at 0.1 mg/mL; 1 w-1, one week old ULH-002 solution at 1 mg/mL; 1 w-10, one week old ULH-002 solution at 10 mg/mL; 1 w-100, one week old ULH-002 solution at 100 mg/mL; Fresh-0.1, fresh ULH-002 solution at 0.1 mg/mL; Fresh-1, fresh ULH-002 solution at 1 mg/mL; Fresh-10, fresh ULH-002 solution at 10 mg/mL; Fresh-100, fresh ULH-002 solution at 100 mg/mL.
