"Huile d'argan, propri\u00E9t\u00E9s pharmacologiques et mise en place d'un processus de contr\u00F4le" . . . . . . "The oil extracted from kernels of Argania spinosa has experienced a real boom in recent years. It can be explained by its nutritional and pharmacological properties due to its high content of unsaturated fatty acids and its unsaponifiable fraction rich in tocopherols, phytosterols, triterpenes and squalene. Studies have showed its action in preventing cardiovascular disease through its ability to lower the cholesterol rate and antioxidant properties. Other studies have highlighted the antiproliferative effect exerted by its polyphenols and tocopherols on prostate tumor cell lines. Also, argan oil is valued for its use in cosmetics because it has stimulating fibroblast proliferation activities, moisturizing and anti-radical ones. The combination of these benefits explains its commercial success. Thus, to sustain this market position, effective control including the determination of the acid rate, saponification, peroxide, iodine but also the unsaponifiable, the specific extinction and percentages of fatty acids is necessary to certify the oil quality. Quantification of minor compounds such as sterols and tocopherols also seems necessary since their variation is accompanied by nutritional and health modifications. Finally, to satisfy the consumer, the organoleptic assessment must be considered. Moreover, several adulteration cases have been prooved in the last past years. To face this phenomenon, oil authentification should be done by dosing the campesterol." . . . . "Huile d'argan" . "L\u2019huile issue des amandons de l\u2019Argania spinosa a connu un r\u00E9el essor ces derni\u00E8res ann\u00E9es. Ceci peut s\u2019expliquer par ses propri\u00E9t\u00E9s nutritionnelles et pharmacologiques dues \u00E0 son importante teneur en acides gras insatur\u00E9s et \u00E0 sa fraction insaponifiable riche en tocoph\u00E9rols, en phytost\u00E9rols, en triterp\u00E8nes et en squal\u00E8ne. Ainsi, des \u00E9tudes ont d\u00E9montr\u00E9 son action dans la pr\u00E9vention des maladies cardiovasculaires gr\u00E2ce \u00E0 ses propri\u00E9t\u00E9s hypocholest\u00E9rol\u00E9miante et antioxydante. D\u2019autres travaux ont mis en exergue l\u2019effet antiprolif\u00E9ratif qu\u2019exercent ses polyph\u00E9nols et ses tocoph\u00E9rols sur des lign\u00E9es tumorales prostatiques. Aussi, celle-ci est valoris\u00E9e pour son utilisation en cosm\u00E9tologie car elle poss\u00E8de des activit\u00E9s stimulantes de prolif\u00E9ration des fibroblastes, hydratante et antiradicalaire. L\u2019ensemble de ces avantages explique son succ\u00E8s commercial. Mais, afin de p\u00E9renniser cette position, un contr\u00F4le efficace incluant la d\u00E9termination de l\u2019indice d\u2019acide, de saponification, de peroxyde, d\u2019iode mais \u00E9galement de l\u2019insaponifiable, de l\u2019extinction sp\u00E9cifique et des pourcentages en acides gras est indispensable pour certifier la qualit\u00E9 de cette huile. La quantification des compos\u00E9s minoritaires tels que les st\u00E9rols et les tocoph\u00E9rols para\u00EEt \u00E9galement n\u00E9cessaire puisque leur variation s\u2019accompagne de modifications nutritionnelles et sanitaires. Enfin, pour satisfaire le consommateur, l\u2019\u00E9valuation des crit\u00E8res organoleptiques doit \u00EAtre entreprise. D\u2019autre part, de nombreux cas d\u2019adult\u00E9ration ont \u00E9t\u00E9 mis en \u00E9vidence ces derni\u00E8res ann\u00E9es. Pour contrer ce ph\u00E9nom\u00E8ne, une authentification par dosage du campest\u00E9rol peut \u00EAtre propos\u00E9e." .
