[2Cp-03] Component analysis of tea seed oil by NMR
Keywords:Tea seed oil, Nuclear Magnetic Resonance (NMR), Fatty acid analysis
Tea seed oil is a high-quality oil obtained from tea seeds, a byproduct of tea cultivation. A number of studies reported that tea seed oil is rich in oleic acid and vitamins and has various health benefits. However, the scientific basis for these benefits is unclear. The purpose of this study is to elucidate the components of tea seed oil by NMR and to reveal its bioactive effects.
The fatty acid (FA) compositions of 57 plant oils, including tea seed oil, were determined from the analysis of 1H NMR spectra. These results were in good agreement with those obtained by the GC method, a common method of FA composition analysis. The tea seed oil produced in Japan showed differences in FA composition, with higher linoleic acid content and lower oleic acid content compared to the Chinese tea seed oil, suggesting that the composition differs depending on the production area. In addition, PCA analysis of the NMR measurement data indicated the possibility of identifying the place of origin. We are currently investigating the bioactive effects of tea seed oil and will report on these results as well.
