Xylan-type polysaccharides were isolated from the leaves of Argania spinosa (L.) Skeels collected in the Tindouf area (southwestern Algeria). Xylan fractions were obtained by sequential alkaline extractions and purified on Sepharose CL-4B. The xylan structure was investigated by enzymatic hydrolysis with an endo-β(1→4)-xylanase followed by chromatography of the resulting fragments on Biogel P2,...

A new phenolic-type compound containing a nitrogenous, heterocyclic-fused ring from the fruit of the argan tree, Argania spinosa (Skeels L.), is described. This and another already known compound also isolated in the course of the work belong to an obscure and rare class of natural products, the amino phenolics.

Populations of the South-western part of Morocco traditionally use the fruits of Argania spinosa (L.) Skeels to prepare an edible oil whose obtainment furnishes, as side product, a cake used to feed the cattle and complemented the forage furnished by the leaves and fruits of this same plant. However, the wood of A. spinosa is also used for fuel and the subsequent induced deforestation is nowada...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for the Moroccan endemic endangered species Argania spinosa with a combination of a typical library enrichment procedure and a 454 GS FLX Titanium-based high-throughput sequencing approach. • METHODS AND RESULTS A genomic DNA library was enriched and further screened using (GA)15, (GTA)8, and (TTC)8 biotin-labeled probes co...

The argan tree, an endemic species in Morocco, has been exhaustively studied its southwestern range but neglected northeastern territory. Thus, the present study sets as objectives identification of arbuscular mycorrhizal fungi and evaluation tree’s roots’ mycorrhization level two stations: one region Béni Snassène (Berkane): Jebel Takermine with 7 prospected sites other at Aklim Alkabir 2 site...
