CERON, Andrés Felipe; OSORIO M, Oswaldo  e  HURTADO B, Andrés. Identification of fatty acids contained in the oils extracted from seeds of three different species of fruit. Acta Agron. [online]. 2012, vol.61, n.2, pp.126-132. ISSN 0120-2812.

The objective of the study was to determine yield in oil and composition in the fatty acids present in three different seeds from Andean fruits: Lulo castilla variety (Solanum quitoense); blackberry castilla variety (Rubus glaucus), and the passion fruit or maracuya (Passiflora edulis). The extraction was carried out by solvent extraction method with a Soxhlet extractor using ethyl ether as solvent at 99.8% to purity and boiling point of 40 - 60 ° C. To identify the fatty acids gas chromatography with FID detector (GC-FID) was used. Oil yields were obtained from 8.5% for lulo, 12.2% for blackberry and 21.2% for maracuya. The fatty acids found were the follow: In seeds of lulo were found palmitic acid 15.6% and linoleic acid 58.1%; in seeds of blackberry 50.1% of linoleic acid and linolenic acid 25.1%; in seeds of maracuya, palmitic acid 15.44%, oleic acid 15.47% and linoleic 63.1%. The fat content of the studied seeds evidence their potential as oleaginous raw material and the identification of the previous fatty acids makes them an important source of components for the food, pharmaceutical or cosmetic industry.
