Bioactive Peptides from Angelica sinensis Protein Hydrolyzate Delay Senescence in Caenorhabditis elegans through Antioxidant Activities

Figure 1

Effect of protein hydrolyzates on survival rates of paraquat-treated C. elegans. Young adult nematodes were pretreated with protein hydrolyzates at indicated concentrations at 20°C for 24 h prior to exposure to 70 mM paraquat, and the survival rates were scored every 12 h. (a)–(d) Representative Kaplan-Meier survival curves of nematodes treated with protein hydrolyzates from Panax ginseng, Fallopia multiflora, Astragalus membranaceus, and Angelica sinensis, respectively.
