Fatty acids qualitative determination from hexane extracts of Neocarya macrophylla seed oil was carried out using gas chromatographyâ??mass spectrometry (GC-MS). The results obtained from the analysis showed that the oil contain the following fatty acids; myristic acid, palmitic acid, stearic acid, palmitoleic acid, elaidic acid, oleic acid, erucic acid, behenic acid, heneicosanoic, icosatetraenoate and eicosatrienoic acid. The results of the Fourier-transform infrared spectroscopy (FTIR) analysis showed 3475.84 cm-1 for bonded and non-bonded â??Oâ??H groups, 2934.79 cm-1, 2869.21 cm-1 and 2037.86 cm-1 The asymmetrical and symmetrical modes of vibration is at the region of unsaturated fatty acid. The ester carbonyl functional group of the triacylglycerols i.e. C=O which showed a very strong and sharp band at 1740.81 cm-1, 1521.74 cm-1 for carboxylic C=O stretching vibrations. The bending vibrations of the CH2 and CH3 aliphatic groups and the in-plane bending vibration of CH cis-olefinic groups are seen at around 1358.9 cm-1. At 721.4 cm-1 and 442.68 cm-1, showed the frequencies of the in- and out-of plane rocking of the cis-olefinic CH2 group and Câ??O stretching vibration (e.g in triacylglycerols) these results showed the potential of this oil in cosmetic industry.
