Sažetak
Kaempferol (3, 5, 7-trihydroxy-2-(4- hydroxyphenyl)-4H-chromen-4-one), one of the most bioactive plant flavonoids was quantitatively investigated for its ability to bind iron and scavange DPPH radical. DPPH reduction test showed kaempferol and its iron complex to be less potent antioxidants towards DPPH radical compared to structurally similar flavone molecules quercetin, baicalein, fisetin, morin, and their iron complexes. The equilibrium geometries of free and complexed kaempferol were optimized with the M05-2X functionals and 6-311G(d, p) basis set.
