Steady-state inhibition of AChE (a), BuChE, (b) and α-Glc (c) by most active fraction (AAC) from A. alnifolia. (a–c) Lineweaver-Burk plot of reciprocal of initial velocities versus reciprocal of substrate concentrations (0.1–0.5 mM) in the absence and presence of AAC at 15, 30, and 90 µg. (ai–ci, aii–cii) Secondary plots of the Lineweaver-Burk plot, slope versus various concentrations of AAC (i) regarding inhibition constant and intercept versus various concentrations of AAC (ii) regarding inhibition constant .
