Ethnobotany, traditional knowledge, and nutritional value of Argan (Argania spinosa (L.) Skeels) in Western Anti-Atlas of Morocco
Braz J Biol. 2022 May 9;84:e260477. doi: 10.1590/1519-6984.260477. eCollection 2022.ABSTRACTThe Souss region in Morocco is known nationally and internationally for its essential knowledge of traditional herbal medicine and the cultural heritage of nutrition. The endemic species Argania spinosa (L.) Skeels is an important crucial plant used by the local population to treat many diseases and prepare some authentic foods. To identify the therapeutic uses of the Argan tree [Argania spinosa (L.) Skeels] and their benefits in preparing authentic foods, the survey was conducted using semi-structured questionnaires. We have achiev...

093 Safety, efficacy and tolerability of a medical device emollient cream containing 30% of urea for xerosis cutis
Emollients and high concentrations of urea are recommended for managing severely dry skin, especially on elbows, knees and heels. Emollients are needed to improve skin hydration and restore skin ’s barrier function. Urea is suitable for treating symptoms like scaling or cracking. The aim of this study was to examine the efficacy, safety and tolerability of a Medical Device (MD) 15102 containing 30% of urea in older patients with xerosis cutis. The studied MD 15102 contained 30% of urea an d emollients: argan oil, avocado oil, glycerin. (Source: Journal of Investigative Dermatology)

Anti-Inflammatory, Antioxidant, Chemical Characterization, and Safety Assessment of Argania spinosa Fruit Shell Extract from South-Western Morocco
Biomed Res Int. 2021 Aug 3;2021:5536030. doi: 10.1155/2021/5536030. eCollection 2021.ABSTRACTArgania spinosa (L.) plays an important role in the Moroccan agroeconomy, providing both employment and export revenue. Argan oil production generates different by-products with functionalities that are not yet investigated, in particular, the shell fruit. The present study aims, for the first time, at evaluating the acute and subacute toxicity, anti-inflammatory, and antioxidant effects of argan fruit shell ethanol extract (AFSEE). The LD50 of AFSEE was determined to be greater than the 5000 mg/kg body weight of mice. No significa...

Molecules, Vol. 26, Pages 4500: Towards a Bioactive Food Packaging: Poly(Lactic Acid) Surface Functionalized by Chitosan Coating Embedding Clove and Argan Oils
Brebu Here we introduce a new method aiming the immobilization of bioactive principles onto polymeric substrates, combining a surface activation and emulsion entrapment approach. Natural products with antimicrobial/antioxidant properties (essential oil from Syzygium aromaticum—clove and vegetal oil from Argania spinosa L—argan) were stabilized in emulsions with chitosan, a natural biodegradable polymer that has antimicrobial activity. The emulsions were laid on poly(lactic acid) (PLA), a synthetic biodegradable plastic from renewable resources, which was previously activated by plasma treatment. Bioactive materi...

Argan (Argania Spinosa) press cake extract enhances cell proliferation and prevents oxidative stress and inflammation of human dermal papilla cells
The hair follicle (HF) along with the epidermis, are considered to be the body's protective barrier against the external environment [1]. The growth of post-natal HF is the result of coordinated processes and signals leading to cellular proliferation and differentiation that occurs in three phases, anagen (growth phase), catagen (degenerative phase), and telogen (resting phase) [2,3]. Mesenchymal-derived cells the dermal papilla cells (DPC), are specialized fibroblasts known to control hair growth cycle. (Source: Journal of Dermatological Science)

Molecules, Vol. 26, Pages 2856: Characterization of Astaxanthin Nanoemulsions Produced by Intense Fluid Shear through a Self-Throttling Nanometer Range Annular Orifice Valve-Based High-Pressure Homogenizer
. Lazarev Stable, oil-in-water nanoemulsions containing astaxanthin (AsX) were produced by intense fluid shear forces resulting from pumping a coarse reagent emulsion through a self-throttling annular gap valve at 300 MPa. Compared to crude emulsions prepared by conventional homogenization, a size reduction of over two orders of magnitude was observed for AsX-encapsulated oil droplets following just one pass through the annular valve. In krill oil formulations, the mean hydrodynamic diameter of lipid particles was reduced to 60 nm after only two passes through the valve and reached a minimal size of 24 nm after eight p...

Nanostructured lipid carriers containing chitosan or sodium alginate for co-encapsulation of antioxidants and an antimicrobial agent for potential application in wound healing
In this study, bioadhesive nanostructured lipid carriers (NLC) were developed for the co-encapsulation of compounds with antioxidant (α-tocopherol and quercetin) and antimicrobial (tea tree oil) activity for management of wounds. The NLC was produced with shea butter and argan oil, and modified with sodium alginate or chitosan to confer bioadhesive properties. Spherical nanoparticles of ~307-330 nm and zeta potential varying from -21.2 to +11.8 mV were obtained. Thermal analysis demonstrated that the lipid matrix reduced tea tree oil thermal loss (~1.8-fold). Regardless of the type of polysaccharide employed, the NLCs pro...

Molecules, Vol. 26, Pages 2516: Optimization of Bioethanol Production from Enzymatic Treatment of Argan Pulp Feedstock
ric Delattre Argan pulp is an abundant byproduct from the argan oil process. It was investigated to study the feasibility of second-generation bioethanol production using, for the first time, enzymatic hydrolysis pretreatment. Argan pulp was subjected to an industrial grinding process before enzymatic hydrolysis using Viscozyme L and Celluclast 1.5 L, followed by fermentation of the resulting sugar solution by Saccharomyces cerevisiae. The argan pulp, as a biomass rich on carbohydrates, presented high saccharification yields (up to 91% and 88%) and an optimal ethanol bioconversion of 44.82% and 47.16% using 30 FBGU/g a...
