Abstract α-Glucosidase inhibition and DPPH free radical scavenging by 5- bromosalicylaldehyde and some Schiff bases have been measured. 5- Bromosalicylaldehyde shows lowest IC 50 value (8.80 μM) for α-glucosidase inhibition and also shows good results in in vivo experiments for antihyperglycemic potential.
