The current research was designed to compare red and white kidney beans (Phaseolus vulgaris L.) for antioxidant, hemolytic and antidiabetic activities. Methodology: Aqueous extract yields were 40.8% (red) and 3.9% (white). The red variety exhibited 45.24±0.76 mg GAE/100g total phenolic content, 137.37±7.72mg CE/100g total flavonoid content and 40.48% free radical scavenging potential. The phenolics, flavonoids and radical-scavenging potential in white beans were 53.40±2.74 mg GAE/100g, 143.25±28.84mg CE/100g and 16.38%, respectively. Regarding alpha-amylase inhibitory potential, 45.25±0.76% and 29.85±0.57% inhibition was observed for red and white beans, respectively. Red bean extract had lower cytotoxicity (3.34%) than that of white bean extract (6.01%). These bioactivities are attributed to the presence of secondary metabolites detected by the Fourier-transform infrared spectroscopy analysis.
It is concluded that both varieties exhibited distinct bioactivities, with red beans showing superior antioxidant radical scavenging and enzyme inhibitory activity, while white beans exhibited comparatively higher phenolic and flavonoid contents. Additional research is required for a complete understanding of the medicinal benefits of Phaseolus vulgaris L.
