Abstract

The chromatography of gases is one of the most versatile methods utilized in the chemical laboratory, which permits the determinations of the percentages and types of fatty acids present in vegetable oils. The objective of this work was to carry out a comparative study of the composition of the fatty acids, of the mechanically extracted oil from the seed of the Jatropha curcasL plant in the raw and refined state, using the data obtained by gas chromatography. The fatty acids of the oil were determined as methylic esteres. The analyst was carried out in a gas chromatographer, with a detector of ionization by way of flame (FID), Agilent 7890A (Agilent, USA) coupled to HP Pentium 4 computer, with a data processing program. The temperatures of the injector and of the detector were 250 °C and 260 °C respectively. The data obtained chromatographically of the oil of Jatropha curcasL, raw and refined indicates that the refinery process did not vary the composition of the fatty acid, because there are no significant differences between them. Also, the results obtained by other investigators, showed that the predominant fatty acids obtained from the oil of the Jatropha curcasL were palmitic and stearic in the saturated fatty acids, and oleic and linoleic in the unsaturated fatty acids.
Key words: chromatography, Jatropha curcasL oil, fatty acid.
