Table 1 IC50 values of β-secretase inhibitory activity of the ethanol extract and its individual fractions from E. bicyclis

From: A novel BACE inhibitor isolated from Eisenia bicyclis exhibits neuroprotective activity against β-amyloid toxicity

Sample IC50 value (mg/mL)*
Ethanol extract 0.70 ± 0.21b
Hexane fraction 1.02 ± 0.11c
Ethyl acetate fraction 0.24 ± 0.08a
H2O fraction 2.12 ± 0.27d
  1. *Values (mean ± S.E.M. of three replications) not sharing a common superscript letter are significantly different (p < 0.05)
