With increasing incidences of diet and nutrition related diseases, objective evaluation of the chemosensory property of taste has gained significance. In this study, aqueous extracts of select medicinal plants of nutritional value (n=72) from five chemosensory groups were studied using proton and carbon NMR spectroscopy. Partial Least Square Discriminant Analysis of 1H and 13C spectral data have shown chemosensory based differentiation. Examples of targeted metabolomics aided identification of chemosensory markers are: β-glucose (sweet), phenylalanine (bitter), gallic acid (astringent) and citric acid (sour). NMR phytometabolomics can be used as a magnetic tongue in deciphering the role chemosensory phytomarkers in nutrition science.
