Повний текст джерелаAcrocomia aculeata (« moucaya », French Guiana creole) is a palm native to French Guiana and the Amazon. Although its fruits are rich in lipids (0.1 to 83% of fresh matter for the mesocarp fruit) and carbohydrates (6 to 98% of fresh matter for them esocarp fruit), only lipi ds are valued as source of biofuels (biodiesel and biokerosene) in the Amazon sub region, due to a lack of knowledge about thechemical nature of carbohydrates. In FrenchGuiana, the fruit is not subject to any valorizationand its antioxidant capacities remain poorly known.To overcome this situation, this thesis work focuses on the extraction, physico chemical and structural characterization of the lipids and carbohydrates (mono --, di --, oligo and polysaccharides) constitutive of the fruit. An evaluation of their antioxidant oremulsifying properties, was also considered. Ourexperiments showed that fruit mesocarps contain 717% oil compared to rich fresh mesocarp, with a chemical composition dominated by oleic (54 62%) and palmitic (23 29%) acids, in line with literature results (53 78 and 11 30% respectively). Regarding carbohydrates, this work identified for the first time the presence of original glucomannanoligo and polysaccharides (fraction F2, 11 22% offresh mesocarp) with remarkable e mulsifyingproperties observed in the case of oligomers (waterin olive oil system (25/75, v v ) at 1% w/v; stability >6 months). In terms of antioxidant activity, the fruit showed no note worthy properties. This preliminary work paves the way for future in vestigations aimed at developing applications for these new glucomannans in the cosmetics, food, and pharmaceutical industries
Bony, Emilie. "Composition chimique et propriétés anti-inflammatoires de l'huile de pulpe d'awara (Astrocaryum vulgare M.)." Thesis, Montpellier 2, 2010. http://www.theses.fr/2010MON20130/document.
Повний текст джерелаAwara (Astrocaryum vulgare M.) is a palm fruit mainly used for nutritional purpose because of its oily pulp. The aim of this study was to characterize awara pulp oil and evaluate its anti‑inflammatory properties in different experimental models. The pulp oil, whose major fatty acids are oleic and palmitic acid, showed a high content of carotenoids. The minor compounds identified are mainly represented by β‑carotene (carotenoids), β‑sitosterol, arundoin (phytosterols) and α‑tocopérol. The pulp oil showed anti‑inflammatory effects in an in vivo model of endotoxic shock by inhibiting the production of proinflammatory cytokines (tumor necrosis factor α (TNFα), interleukin (IL)‑6) and increasing the production of an anti‑inflammatory cytokine (IL‑10). These anti‑inflammatory effects have been confirmed in an in vivo model of airway inflammation. The pulp oil has reduced the influx of inflammatory cells in the lungs, mainly of eosinophils and lymphocytes. The unsaponifiable fraction has subsequently shown inhibitory effects on the production of various inflammatory mediators (nitric oxide, prostaglandin E2, TNFα, IL‑6, IL‑10) and on the expression of enzymes induced during inflammation (iNOS and COX‑2) in an in vitro model of activated macrophages. The unsaponifiable fraction also showed an inhibitory effect on cytokine production (TNFα, IL‑6 and IL‑10) in endotoxic shock model. These results confirm the role of micronutrients of awara pulp oil in its anti‑inflammatory properties and suggest a preventive and/or therapeutic role of awara pulp oil and its unsaponifiable fraction in inflammation‑related diseases
