Identification of Digestive Enzyme Inhibitors from Ludwigia octovalvis (Jacq.) P.H.Raven

Figure 3

Concentration–response graphics for half–maximal Inhibitory Concentration (IC₅₀) determination of CsHAE, LoHAE, LoEAF, C1F1 (isolated ethyl gallate), and C2F1 (isolated gallic acid), in the inhibition model of α–glucosidases. X-axis values are presented in μg/mL (real values are logarithmic). The error bars represent the standard deviation of 2 measurements in four separate sample runs (n = 8).
