Flavonols and flavonoids: UV spectroscopic analysis

Date: Nov 1, 2016

Author: David Bradley

Various spectroscopic methods, including UV-Vis, infrared, Raman, nuclear magnetic resonance spectroscopy and electrospray ionization mass spectrometry have been used to investigate the relationship between the molecular structure and biological activity of hydroxyflavonol metal complexes. UV-Vis emerges as the most efficient in understanding the interaction of flavonols with DNA.
