Activities of antioxidants, α-glucosidase inhibitors and aldose reductase inhibitors of the aqueous extracts of four Flemingia species in Taiwan.

The aim of this study was to examine the possible antioxidant and antidiabetic effects of the aqueous extracts of four Flemingia species in Taiwan. A number of methods were employed for this investigation, including ABTS radical monocation scavenging, FRAP (ferric reducing antioxidant power) method, DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging, total polyphenol content, total flavonoid content, total flavonol content, and inhibition...
