Revealing the 1H‐NMR Profiling of Six Edible Mushrooms Consumed in the Northeastern Highlands of Puebla, Mexico

Abstract The 1 H‐NMR metabolomics profiling of six edible mushrooms consumed in the northeastern highlands of Puebla, Mexico is presented. These fungi were morpho‐ and molecularly identified as Infundibulicybe squamulosa , Amanita jacksonii , Lepista nuda , Russula delica , Russula brevipes , and Lactarius indigo . The chemical profiling confirmed the presence of eight essential amino acids and their derivatives, six organic acids, six nucleosides, low amounts of reducing sugars, and valuable nutraceuticals such as betaine, carnitine, glycero‐3‐phosphocholine and O‐acetylcarnitine which were differentially determined and quantified in the six mushrooms by qNMR. Principal component analysis (PCA) and orthogonal projections to latent structures discriminant analysis (OPLS‐DA) generated four different groups. Two of these groups were constituted by fungal species with phylogenic relationships whereas non‐phylogenetic related species were separated from each other. The potential use of 1 H‐NMR metabolomics and chemometrics to group macromycetes and determine the nutritional and nutraceutical potential of these local foods is demonstrated.
