Walnut oil is endowed with a variety of physiological functions due to abundant natural compounds, and the effect of unsaturated fatty acids is crucial. In order to accurately and conveniently detect the fatty acids components and content in walnut oil, a quantitative method was developed to detect fatty acids content based on the 1H-NMR and 13C-NMR techniques. In addition, HPLC combined with MS was used to conduct qualitative analysis. HPLC method with an evaporative light-scattering detector was for the quantitative analysis and the fatty acids content was compared with the content from NMR. The result showed that there was no significant difference between 1H-NMR, 13C-NMR and HPLC (P > 0.05) and indicated that the NMR has the potential to be applied as a routine method for the analysis of fatty acids content in walnut oil.
