With increasing interest in the role of taste related fatty acids in food, pharmacology, health and diseases, objective study of this chemosensory parameter has assumed importance. The potential of NMR metabolomics to fingerprint chemosensory properties has been explored in the context of non-polar phytocompounds in this study. Non-polar fractions obtained by dual phase (chloroform-methanol/water) extraction of select dietary plants (n=24) were studied using proton NMR spectroscopy. Partial Least Squares Discriminant Analysis of the spectral data showed distinct chemosensory based clustering. NMR based chemosensory studies of non-polar phytocompounds could open new applications in sensorial sciences related to lipids and fatty acids.
