Cholinesterase inhibition assay: The AChE and BChE inhibiting activities were measured by the spectrophotometric method developed by Ellman et al. 1962. Electric-eel AChE (EC 3.1.1.7), horse-serum BChE (E.C 3.1.1.8), acetylthiocholine iodide, butyrylthiocholine chloride, 5, 5′-dithiobis [2-nitrobenzoic acid] (DTNB), and galanthamine were purchased from Sigma (St. Louis, MO, USA). All other chemicals were of analytical grade. Standard operational assay protocol has been described previously. All the kinetic experiments were performed in 96-well microtiter plates by using SpectraMax 340 (Molecular Devices, CA, USA). The rate of the enzymatic reaction was measured by the following equation. Rate(mol/L/min ) = Change in absorbance/min/13,600.

Statistical analysis. Graphs were plotted using GraFit program. Values of the correlation coefficients, slopes, intercepts, and their standard errors were obtained by the linear regression analysis using the same program. The correlation of all the lines of all graphs was found to be >0.99. Each point in the constructed graphs represents the mean of three experiments.
