Oil extracted from the seeds of Quercus dilatata with the help of soxhlet apparatus, using petroleum ether as solvent, was analysed for its physico chemical constants and composition of fatty acids. The analytical data obtained were compared with those of oil from Quercus ilex, Quercus incana and Quercus glauca, (5, 6, 7, 8, 10). It was concluded that this oil, being non-drying in nature and have no toxic compounds, can be used for edible purposes. The seeds, which were analysed for protein, carbohydrate and ash, indicate that they can be utilized as poultry and livestock feed (9).
