Lineweaver-Burk plots of -amylase (a) and -glucosidase (b, c, and d) activities by S. aristolochiifolia root extract (SAR), chlorogenic acid-rich fraction (CAF), and astilbin-rich fraction (ABF). The kinetics was assayed in the absence (control) and the presence of three different concentrations of each preparation.
