In order to choose from the variety of oleaginous plants for biodiesel production, the oil content of several matrices was determined through different experiments of low-field 1H Nuclear Magnetic Ressonance (NMR) with varied pulse sequences, namely single pulse, spin-echo, CPMG and CWFP (Continuous Wave Free Precession). The experiments applying the first three sequences showed high correlation with each other and with the solvent extraction method. The best results were achieved through CPMG experiments. When the CWFP sequence was used, the correlation with the solvent extraction method was very low and the results were not compatible with those employing the other sequences. Quality of the vegetable oils was also evaluated. The study was...
