The powder obtained was identified as date palm seed powder (DPSP). The composition (w/w) of the DPSP has been reported in our previous paper as protein, 5.64%, moisture, 5.39%, fat 8.14%, fibre 18.50%, ash 0.95%, carbohydrate 61.38%
Oil was extracted from DPSP using a Soxhlet apparatus. Fifteen gram samples of dried DPSP were weighed into an extraction thimble
and sealed with cotton wool. The thimble was inserted in a Soxhlet extraction flask and extracted with boiling hexane (boiling point 68 °C) for 10 h or until the solvent at the sample chamber was colourless,
