摘要

A critical overview of recent developments of NMR spectroscopy in natural products and food chemistry will be provided with emphasis in the following applications: (i) chemical analysis of extracts without isolation or derivatization steps [1-5], (ii) 'in situ' direct monitoring of dynamic changes of metabolites as a function of solvent and temperature [6], (iii) aromatic C-H activation of flavonoids in aqueous solution at neutral pH and ambient temperatures [7], (iv) rapid 'in situ' analysis of enzymatic reaction products and enriching the biological space of natural products, through real time biotransformation monitoring [8] and (v) in-cell NMR in decoding the apoptotic activity of flavonoids with the Bcl-2 family of proteins [9]. Despite the significant advantages in methodology and the fact that NMR is a potentially primary analytical technique for qualification, much effort should be made in the future so that international compatibility can be achieved for a wide range of chemical constituents in natural products and in food chemistry. Selected examples of certified reference materials will be provided.
