Tin(II)-quercetin complex: Synthesis, spectral characterisation and antioxidant activity

► Tin concentrations of canned foods increase with storage time and temperature. [79] ► Quercetin is able to chelate metal ions. ► We synthesize and characterise quercetin-Tin(II) complex. [58] ► Chelation of Tin(II) induced a bathochromic shift in absorbance band I. ► Antioxidant activity of quercetin decreased after chelating of Tin(II). [74]
