Flavonoids are considered as a significant class of compounds among the natural products,
exhibiting a variety of structural skeletons as well as multidirectional biological potentials. In structural
elucidations of natural products, Nuclear Magnetic Resonance (NMR) spectroscopy has been
playing a vital role; the technique is one of the sharpest tools in the hands of natural products chemists.
The present resume deals with hard-core applications of such spectral technique, particularly in
structural elucidation of flavonoids; different NMR techniques including 1H-NMR, 13C-NMR, and
2D-NMR [viz. 1H-1H COSY, COLOC, HMBC, HMQC] are described in detail.
