The fatty acid composition of date seed oil from two different date palm ( Phoenix dactylifera L.) cultivars, locally known as Degla-Baïdha and Tafezouine, were investigated. GC analysis revealed the presence of five dominant fatty acids: oleic C18:1 (46.51; 39.15%), lauric C12:0 (22.1; 28.5%), myristic C14:0 (10.7; 11.4%), palmitic C16:0 (9.6; 8.7%) and linoleic C18:2 (6.9; 6.1%). The oils was characterised by a low content of tocopherols (0.53; 1.41 μg/g). The antioxidant activity of the oils was investigated using the DPPH•(1,1-di-phenyl-2-picryl-hydrazyl) scavenging assay. The oils had a weak bleaching effect on DPPH• free radicals. This study showed that the qualities of the tested oils are highly comparable with those of some commercial seed oils of other plants. Furthermore, a statistical analysis using the hierarchy ascendant classification method was conducted in order to highlight the similarities and/or the differences regarding the contents of the main fatty acids found in some common plants and in the five most famous cultivars of Phoenix dactylifera of south eastern Algeria (Tafezouine, Degla-Baïdha, Deglet-Nour, Ghars, Tamdjouhert).

Phoenix Dactylifera L

Studies were conducted on some quality characteristics of date seed oil from two date palm cultivars ( Phoenix dactylifera L.): Deglet Nour and Allig. The following values were obtained for Deglet Nour and Allig cultivars respectively: unsaponifiable matter 8.92-7.76%, iodine value 45.49-44.08, total phenols 520.81-220.32µg/g oil, chlorophylls 0.86-0.58µg/g oil, viscosity 18.50-20.50mPa.s, refractive index 1.457-1.462, acidity 1.06-2.10mg KOH/g oil and peroxide index 16.00-25.00meq O2/100g oil. Lipid fractionation of date seed oil yielded 98.30-97.30% neutral lipids, 97.26-96.90% triglycerides, 0.25-0.18% phospholipids and 0.36-0.31% sterols. Gas-liquid chromatography revealed that the major unsaturated fatty acid was oleic acid (39.17-42.13%) while the main saturated fatty acid was lauric acid (24.34-22.56%). Date seed oil showed high medium molecular weight triglycerides (C32-C42, about 27%). Extinction coefficients at 232nm and 270nm increased slightly during 40days in oven (60°C) showing that date seed oil could be easily stored. The production of oil from date seeds provides the use of a renewable resource, and at the same time adding value to agricultural products.

This work focuses on the extraction of oil from date palm seed. Using n-hexane in Soxlet extraction apparatus, standard procedures were followed to determine the oil feed stock yield. Proximate compositions and physicochemical characteristics were carried out. Also, Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography Mass Spectrometry (GC-MS) were used to determine the functional groups and the fatty acid composition of the oil respectively. The result shows that the appearance of date palm seed oil is reddish brown in colour. Result from the FTIR analysis also shows that 17 peaks were noticed from date palm seed oil, indicating the presence of various functional groups such as OH, C-H, C=C, C=O, C  The dominating types and number of functional groups are found on the single bond stretch and on the fingerprint region skeletal vibration. Similarly, the GC-MS result also reveals that there are 5 dominating fatty acid compounds present in date palm seed oil in relation to their abundant relative weight composition. In date seed oil, oleic acid which comprise of omega-9 fatty acid is found to be the only monounsaturated fatty acid with the highest weight composition of 49.4%. The inference that can be drawn from the results in this work in relation to application suggest that, date palm seed oil will be suitable for soap production and cleansing agents. Also, omega-9 fatty acid has some health benefits that can strengthen the brain as well as the heart. Furthermore, research on the life shelf and storage of this oil should be looked into, as it relates to the peroxidation of oil.

Abstract The present study characterizes seed-related traits, phytochemical, physiochemical parameters and fatty acid profile of shea (Vitellaria paradoxa) seeds collected from the Kosubosu, Fufu and Sare areas of Kwara State, Nigeria to determine the effects of microclimate on seed morphology, biochemical and oil constituents. Seed morphological data were analyzed for variability. Seed oil was extracted for phytochemical constituents, physicochemical properties, and fatty acid profiling by gas chromatography equipped with mass spectrometry (GC/MS). Results showed intra and inter-locational variations in seed characters. Most fruits had 1–2 seeds. Seeds were predominantly brown and very few were dark brown. Phytochemicals and physicochemical parameters of the seed oil varied with place of collection. Alkaloid, saponin, tannin and phytate contents ranged between 0.79–0.84, 1.20–1.26, 1.48–1.56 and 0.15–0.18 mg g−1 respectively. The density of the oil was less than that of water, acid value ranged from 10.58–13.56 mg KOH g−1 and iodine values were between 36.63 to 40.32 g I2 (100 g)–1. Saponification values lie between 160.39 and 184.14 mg KOH g−1; and free fatty acid was within 5.32–6.81 %. Peroxide, ɑ-tocopherol, total phenol and oxalate values as well as viscosity of the oil also varied; however, refractive index was similar. Ethyl oleate and octadecanoic acids were present and most abundance in all the locations, while glycidol stearate was only found in Fufu samples with three other fatty acids. Five fatty acids were present in Kosubosu, while Sare had only two. The results obtained in the present study indicate that shea oil could be used for medicinal, nutritional and industrial purposes. Since seed characters, phytochemical, physicochemical and fatty acid compositions varied with the microclimate, environmental and micro-ecological conditions should be considered when collecting seeds for oil utilization.

Date palm seed is one of the waste by-products generated from industrial commodities. Date seed oil can be obtained through solvent extraction using a Soxhlet apparatus. In this experiment, date palm seed was used as raw material with ethyl acetate as the solvent. The experiment was carried out by varying extraction time and the mass ratio of date palm seed to solvent. The highest oil concentration of 9.5% was obtained at date palm seed to solvent mass ratio of 1:6 with extraction time of 2 hours. Peroxide value, iodine value, specific gravity, and free fatty acid content of date seed oil were, consecutively, 0.81 meq/kg oil, 10.15 mg/g, 0.80, and 0.52%. The highest fatty acid composition of date seed oil was oleic acid at 37.22% followed by lauric acid at 19.36%.

The present investigation aimed to assess the effect of pollen sources on the mass, dimension, oil content and fatty acid profile of the seeds from female palms of the Medjool date cultivar. The palms were pollinated with Deglet Noor, Khadrawy, Medjool and Zahidi cultivars. In addition, three palms were pollinated as the treatment control. The fatty acids were evaluated by gas chromatography-mass spectrometry. The surface morphology of date seed powder was examined using SEM, before and after n-hexane interaction. The seeds of the Medjool treatment had the greatest mass (1.42 g), but the lowest oil content (5.37% w/w); the control seeds showed smaller mass (1.21 g), but higher oil content (13.57% w/w). The proportion of fatty acids varied significantly among the treatments with respect to the control. The most abundant fatty acids were oleic (C18:1), lauric (C12:0), myristic (C14:0), palmitic (C16:0), linoleic (C18:2), and stearic (C18:0). Together these fatty acids presented a composition between 98.3 and 98.67% for treatments, and 99.0% for the control. The results indicate that the pollen sources from Deglet Noor, Khadrawy, Medjool and Zahidi cultivars had a significant effect on mass, dimension, oil content and fatty acid profile of the seeds of the date cultivar Medjool. The date seed oil could be used as edible oil, in food products, and in pharmaceutical and cosmetic applications.
