DPPH scavenging effects of Qu, DNPs, and QNPs. (A) The graph indicates that Qu had most free radical scavenging activity compared to QNPs and DNPs; and its activity increased along with elevating concentration, while its activity didn’t depend on time. (B) The graph of DNPs activity showed lowest free radical scavenging activities. Except for dose 10 µg.mL⁻¹ which had no effect, DNPs indicated improvement in their activities along with increasing concentration and time. (C) The graph indicated QNPs had dose- and time-dependent free radical scavenging effects (n=3, mean ± SEM). *p<0.05, **p<0.01, ***p<0. 001, and ^#p<0. 0001.
