In the Arab Republic of Egypt, efforts have been made to improve the productivity of wood to meet the great need every year.
The identification of any useful by-products will enhance the chances for the successful commercialization of the production of wood.
In addition, there has been an acute shortage of oils and fats, especially during the last 15 years.
This situation led to a search for other sources of oil, and seeds of a large number of commonly grown vegetables, fruits and wild plants have been screened for their oil content.
The oil content of Khaya senegalensis A. Juss, Khaya ivorensis A. Chev and Swietenia mahogani Jacq. seeds was determined by two solvents i.e. hexane and petroleum ether at different durations (30 min., 1hr., 2hr. and 4hr.)
The oil % of Khaya senegalensis seeds was 24.98, 21.33, 21.15 and 19.14 respectively, when extracted by hexane.
As for those extracted by petroleum ether, oil % was 26.59, 16.84, 16.13 and 16.84 respectively.
Regarding K. ivorensis seeds extracted by hexane the oil % was 27.03, 19.88, 19.86 and 17.87, while in the case of petroleum ether extraction it was 27.06, 19.12, 18.47 and 17.21 respectively.
Concerning Swietenia mahogani seeds extracted by hexane the oil % was 36.12, 21.08, 19.45 and 18.53, and for those extracted by petroleum ether the oil % was 32.40, 21.64, 20.39 and 18.16, respectively.
Iodine value, acidity and refractive index values were determined.
AG.L.C. analysis and the relative proportions of fatty acids were determined.
