Inhibition of yeast α-glucosidase by CZ extract. A. Inhibition of α-glucosidase by CZ extract at various concentrations (1-16 μg/ml). B. Inhibition α-glucosidase by acarbose at various concentrations (1-60 μg/ml). The α-glucosidase inhibition was analyzed by measuring p-nitrophenol released from PNPG at 405 nm after 30 minutes of incubation at 37°C. Results are expressed as mean of percent inhibition ± S.E.M against log 10 concentration of inhibitor.
