3 Advances in analytical methodology applied to Leguminosae flavonoids 

Hyphenated analytical methods used in studies of flavonoids fall into several categories, the most important of which involve mass spectrometry (MS, usually as LC-UV-MS see 

Section 2.3.1), nuclear magnetic resonance spectroscopy (NMR, usually as LC-NMR see Section 2.3.2), and less commonly, circular dichroism (CD) or capillary electrophoresis (CE) (Section 2.3.3). A useful overview of these techniques in flavonoid research has been given by de Rijke et al. (2006), and some specific applications in legume chemistry are
