Cellulosic and hemicellulosic fractions dosage of Pistacia atlantica Desf. subsp. atlantica leaves in western Algeria.

The aim of this study was to valorise a deciduous tree called Pistacia atlantica. Cell wall polysaccharides (cellulose and hemicelluloses) were isolated and dosed from mature and young pistachio leaves. The samples were collected from six different locations in the Sidi Bel Abbes region (western Algeria). The wall residue yield varied from 39.06% to 69.5%.The cellulose and the hemicellulose's cell wall yield varied from 21.25% to 40.6% and from 0.11% to 13.6%, respectively [corrected]. In the mature leaves, the cellulosic fraction is more important than the hemicellulosic fraction. The highest yield is noted in the young leaves.
