Protective effect of argan oil on mitochondrial function and oxidative stress against acrylamide-induced liver and kidney injury in rats.
Conclusion: Over recent years, compounds that specifically target mitochondria have emerged as promising therapeutic options for patients with hepatic and renal diseases. We think that AO oil is one of these compounds due to its unique content.

Unveiling the Microbiota Diversity of the Xerophyte Argania spinosa L. Skeels Root System and Residuesphere.
Abstract
The microbiota associated to xerophyte is a "black box" that might include microbes involved in plant adaptation to the extreme conditions that characterize their habitat, like water shortage. In this work, we studied the bacterial communities inhabiting the root system of Argania spinosa L. Skeels, a tree of high economic value and ecological relevance in Northern Africa. Illumina 16S rRNA gene sequencing and cultivation techniques were applied to unravel the bacterial microbiota's structure in environmental niches associated to argan plants (i.e., root endosphere, rhizosphere, root-surrounding s...

Argan oil ameliorates sodium fluoride-induced renal damage via inhibiting oxidative damage, inflammation, and intermediate filament protein expression in male rats.
This study was designed to investigate the potential protective effect of AO supplementation as pre-treatment or co-treatment on sodium fluoride (NaF)-induced nephrotoxicity in rats. Male Sprague Dawley rats (n = 50) were randomly assigned to one of five equal groups: control group, AO-treated group (6 ml/kg b.wt.), NaF-treated group (20 mg/kg b.wt.), pre-treated group, and co-treated group. All rats were daily administered by oral gavage for duration of 30 days. The results showed that AO administration significantly improved renal function and antioxidant status and decreased the lipid peroxidation in NaF-treated ...

High-throughput screening of argan oil composition and authenticity using benchtop 1 H NMR.
Abstract
We use 60MHz benchtop NMR to acquire 1 H spectra from argan oils of assured origin. We show that the low-field NMR spectrum of neat oils contains sufficient information to make estimates of compositional parameters and to inform on the presence of minor compounds. A screening method for quality and authenticity is presented based on nearest-neighbour outlier detection. A variety of oil types are used to challenge the method. In a survey of retail-purchased oils, several instances of fraud were found.

Zebrafish toxicity assessment of the photocatalysis-biodegradation of diclofenac using composites of TiO2 and activated carbon from Argania spinosa tree nutshells and Pseudomonas aeruginosa.
In this study, we focused on the ability of photocatalysis or combined photocatalysis and biodegradation to effectively and safely remove diclofenac (DCF) and its by-products from water. The heterogeneous photocatalysis system was based on bio-sourced activated carbon obtained from Argania spinosa tree nutshells and Degussa P25 titanium dioxide (ACP-TiO2), and biodegradation involved Pseudomonas aeruginosa. Toxicity tests were conducted with zebrafish embryos to evaluate the applicability of the treatment processes. The results showed that photocatalytic treatment with 0.1 mg/L of ACP-TiO2 9% for 7.5 h is sufficient to e...

Formation and Stability of Emulsions Using Crude Extracts as Natural Emulsifiers from Argan Shells
This study evaluated the emulsifying performance of five aqueous-ethanolic argan shell (Argania spinosa L.) crude extracts. We aim to compare crude extracts originating from the same raw material to produce stable oil-in-water (O/W) emulsions. First, surface-active compounds (i.e. saponins, proteins, and polyphenols) were quantified and interfacial tension against soybean oil of the extracts was assessed. We report here that despite the variation in the composition, the crude extracts were capable of similarly reducing the interfacial tension at the soybean oil/water interface to an average of 11 mN/m. Nevertheless, when...

Optimization of semi-anaerobic vitamin B12 (cyanocobalamin) production from rice bran oil using Propionibacterium freudenreichii PTCC1674
Publication date: Available online 26 November 2019Source: Biocatalysis and Agricultural BiotechnologyAuthor(s): Rouhollah Hedayati, Morteza Hosseini, Ghasem D. NajafpourAbstractVitamin B12 contributes many substantial metabolic cycles in the living organisms. Since human beings cannot produce such co-factor by their metabolism, they have to receive this vitamin from foods and supplements. Dimethylbenzimidazole (DMBI) distinguishes the active form of vitamin B12 from pseudo-vitamin B12. De Novo total biosynthesis of vitamin B12 in the bacteria should include DMBI biosynthesis through riboflavin pathway. Propionibacterium f...

Anti-inflammatory activity of argan oil and its minor components.
We report that argan oil and its "minor" components effectively lessen the inflammatory actions of carrageenan. Far from being "pharmacological" the actions of argan oil are comparable with those of diclofenac in the short, i.e. 4 h term. Sustained consumption of argan oil might, therefore, contribute to lessen the burden of degenerative diseases associated with higher inflammatory status.
