    Author(s): Maitera ON*, Louis H, Barminas JT, Akakuru OU and Boro G

    The article describes the synthesis and characterization of Ni-flavonoid complex, Cu-flavonoid complex and Znflavonoid complex. The complexes and the flavonoid extracts were characterized using FTIR and UV-Visible spectrophotometer. The results for FTIR spectra clearly showed the formation of complexes as the bands assigning to the carbonyl group C=O shifted to the lower wave number when compared with that of the free ligands. The complexes and the flavonoids extracts when analyzed using UV-Visible spectrophotometer, most of the spectra of the complexes were absorbed at the range of 200 nm to 400 nm and all the spectra of the flavonoids extracts were also absorbed between 200 nm to 400 nm. These results revealed that complexes were formed at slightly acidic condition between the pH values 3.51 to 4.65. In general the results revealed that the conductivity values of Niflavonoid complex.. View More»
