“…These inverse variations in fatty acid composition permit to obtain a similar degree of unsaturation in the three types of oils. However, the concentrations reported in the present study correspond to the scale of values reported by different authors (Berrada, 1972;Farines et al, 1984b;Maurin, 1992;Rezanka & Rezankova, 1999;Yaghmur et al, 2001;Drissi et al, 2004) can consider that the profile of unsaturated fatty acids in argan oil is comparable for the three types of fruits. As commercial production is currently made from a blend of argan fruits, the composition of oil would not show notable variations in fatty acids and this relative stability might confer to this oil the quality of a standard.…”

“…However, different results on chemical composition of argan oil, especially in the case of unsatured fatty acids and tocopherols, were reported. Indeed, values ranging from 42.8% to 55.4% and from 24.4% to 37.4% were found for oleic and linoleic acids, respectively (Berrada, 1972;Farines et al, 1984b;Maurin, 1992;Rezanka & Rezankova, 1999;Yaghmur et al, 2001;Drissi et al, 2004). Tocopherol contents also ranged from 165 and 637 mg/kg (Huyghebaert & Hendrickx, 1974;Farines et al, 1984a;Drissi et al, 2004).…”

Abstract.-Argan oil was extracted with a soxhlet apparatus from nuts of spindle-shaped, oval, or round fruits. A significant difference was found in extraction output; 11.55, 8.50 and 5.02 kg of oil/100 kg of kernels were recorded in oval, round and spindle-shaped fruits, respectively. The concentrations of oleic and linoleic acids in the three types of fruits were also significantly different. Indeed, the content of oleic acid was higher in oval fruits (46.73%) than in spindle-shaped (45.53%) and round (41.52%) fruits. A greater content of linoleic acid was found in round fruits (38.38%) than in oval fruits (33.54%). The differences in tocopherol composition were more obvious. The highest content (1568.60 mg/kg of oil) was found in spindle-shaped fruits, followed by round (1141.60 mg/kg) and oval (583.80 mg/kg). Significant differences between the three types of tocopherol contents were noted and were greater for gamma-tocopherol.Key words : argan oil -fatty acids -output -tocopherols.Résumé.-L'huile d'argan a été extraite au soxhlet à partir d'amandes de trois types de fruits classés slon leur forme. Le rendement d'extraction est significativement différent ; 11,55 , 8,50 et 5,02 kg d'huile/100 kg de graine respectivement pour les fruits ovales, arrondis et fusiformes. L'analyse chimique montre que la composition en acides oléique et linoléique est significativement différente dans les trois huiles. Ainsi, l'acide oléique présente une teneur plus élevée dans le fruit ovale (46,73%) que dans les fruits fusiformes (45,53%) et arrondis (41,52%). L'acide linoléique présente une teneur plus importante dans le fruit arrondi (38,38%) que dans le fruit ovale (33,54%). Quant à la composition en tocophérols, les différences sont encore plus marquées : 1568, 1141 et 583 mg/kg d'huile pour les fruits fusiformes, arrondis et ovales. Les différences significatives portent aussi sur les trois classes de tocophérols. Elles sont, cependant, plus importantes pour le gamma-tocophérol.

“…Consequently, argan oil consumption clearly reduces cardiovascular risks, and argan oil can be used as an antiatherogenic oil [26]. In addition, argan oil has been shown to possess antioxidant properties [27,28]. Minor components of argan oil are also likely to be responsible for some of its pharmacological properties [29].…”

Edible argan oil is traditionally prepared by Berber women who manually crunch the roasted kernels of Argania spinosa fruits. Unroasted kernels furnish a cosmetic-grade oil. Argan groves are currently shrinking due to unfavorable conditions. To stop this trend, a program aimed at increasing the argan tree economical value is in progress in Morocco. Its concept is that the natives will preserve argan trees only if the major part of the wealth resulting from the argan grove production directly benefits them. Because of its high dietary value, argan oil has appeared as the best derivative to rapidly satisfy such assumption. Consequently, year after year, cooperatives have been implanted to produce argan oil of high quality on a large scale. The delicate hazelnut taste of argan oil, combined with its high level in unsaturated fatty acids, has allowed its swift commercial success and, nowadays, argan oil of standardized quality is marketed worldwide. Moroccan farmers are now beginning to plant argan trees, confirming the full success of this ambitious program. This review summarizes the methods used to prepare argan oil, its composition, the strategies available to certify argan oil quality, and finally the impact of argan oil on human health.

“…De ce fait, nous pouvons conclure que l'ingestion d'huile d'argan n'augmente pas la sensibilité des cellules endothéliales au stress oxydatif. Drissi et al [21] ont montré que grâce à sa teneur en antioxydants, particulièrement les tocophérols, la consommation de l'huile d'argan induit une augmentation de la concentration de a-tocophérol et une diminution des lipopéroxydes plasmatiques, amélio-rant ainsi le statut antioxydant chez des personnes saines. Ces résultats permettent aussi de suggérer que l'ingestion de l'huile d'argan affecte surtout le profil lipidique dans le cas où aucune pathologie vasculaire n'est reportée.…”
