  • High-Field Nuclear Magnetic Resonance (NMR) Study of Truffles (Tuber aestivum vittadini)
    Journal of Agricultural and Food Chemistry, 2004
    Co-Authors: Luisa Mannina, Michela Cristinzio, Anatoli P. Sobolev, Pietro Ragni, Annalaura Segre
    Abstract:

    A high-field NMR technique was used to analyze aqueous and organic extracts of truffles (Tuber aestivum vittadini) to characterize their chemical composition. Water-soluble metabolites belonging to different classes such as sugars, polyols, amino acids, and organic acids were almost completely assigned by means of one- and two-dimensional experiments (1H−1H COSY, TOCSY, 1H−13C HSQC, 1H−13C HMBC, and 1H−31P HMBC). The 1H spectral assignment of the cell membrane components such as lipids, sterols, and fatty acids extracted in organic solvents was also performed. Keywords: Truffles; Tuber aestivum vittadini; chemical composition; metabolites; NMR

  • Metabolic profile of lettuce leaves by high‐field NMR spectra
    Magnetic Resonance in Chemistry, 2005
    Co-Authors: Anatoli P. Sobolev, E Brosio, Raffaella Gianferri, Annalaura Segre
    Abstract:

    A detailed analysis of the proton high-field NMR spectra of aqueous and organic extracts of lettuce leaves is reported for the first time. A combination of COSY, TOCSY, 1H–13C HSQC, 1H–13C HMBC bidimensional sequences and DOSY was used to assign each spin system and to separate the components of the complex patterns. A large number of water-soluble metabolites belonging to different classes such as carbohydrates, polyols, organic acids and amino acids were fully assigned. Moreover, the complex spectra of metabolites extracted in organic solvents belonging to sterols, fatty acids, diacylglycerophospholipids, galactosyldiacylglycerols, sulpholipids, pheophytins, carotenoids and hydrocarbons were also assigned.
