13C NMR Spectroscopy of Flavonoids

Pawan Kumar Agrawal and Ram Prakash Rastogi*

*Central Drug Research Institute, Lucknow 226001, India


A survey of 13C NMR spectroscopy data of the various classes of flavonoids is presented which shows that the carbon resonances of ring C are useful in identification of the basic skeletal type. The applications of this data in structure elucidation studies such as determination of the positions of alkylation, acylation, glycosylation etc. are reviewed.
