1H NMR spectra dataset and solid-state NMR data of cowpea (Vigna unguiculata)

Abstract

In this article the NMR data from chemical shifts, coupling constants, and structures of all the characterized compounds were provided, beyond a complementary PCA evaluation for the corresponding manuscript (E.G. Alves Filho, L.M.A. Silva, E.M. Teofilo, F.H. Larsen, E.S. de Brito, 2017) [3]. In addition, a complementary assessment from solid-state NMR data was provided. For further chemometric analysis, numerical matrices from the raw 1H NMR data were made available in Microsoft Excel workbook format (.xls).

Keywords: 1H qNMR; CP-MAS; Chemometrics; Cowpea seeds; SP/MAS.
