Synthesis, spectroscopic, and molar conductance characterization of selenium(IV) vitamin B6 complex as prospective antioxidant agent
2014
Selenium(IV) complex of vitamin B6 has been prepared using Se(IV) tetrachloride and characterized using spectroscopy (IR, UV-Vis, H NMR), molar conductance measurements, thermal analysis (DTA and TGA) and SEM imaging. Micro-analytical and spectral data show that the formed selenium(IV) complex is 1 : 2 (Se : vitamin B6) molar ratio. Vitamin B6 and its selenium complex were screened for in vitro antioxidant activity. The complex exhibited stronger antioxidant activity in 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical assay compared to the free vitamin B6 ligand.
