Liensinine and neferine delayed Aβ-induced toxicity in C. elegans. (a) Percentage of nematodes not paralyzed at various liensinine and neferine concentrations (50,100,200µM). (b) The PT50 was used for quantitative analysis, which represents the time interval from the beginning of paralysis to 50% of nematode paralysis. (n = 3, *p < 0.05; **p < 0.01) Each group contains more than 30 nematodes
