Phytochemical compositions and antioxidant capacity of three date (Phoenix dactylifera L.) seeds varieties grown in the South East Morocco
Three Moroccan date seeds (Phoenix dactylifera L.) varieties (Majhoul, Boufgous and Bousthammi) were evaluated for their proximate, phytochemical and nutrient compositions. The crude fiber ranges between 15.84–19.9 g/100 g DW, moisture (4.554–8.259%), protein (4.309–6.144% of DW), ash (1.097–1.3% DW...
