Dried melon seeds (Citrullus colocynthis L.) of the family Cucurbitaceae were investigated for nutritional quality and the oil seed characteristics. These melon seeds, on a dry weight basis, consisted of 52.3% of test and 47.7% of kernel. The moisture content in melon seeds was 54.5% and the mineral constituents were also determined. The oil content of seeds was very high ranging from 22.1-53.5%, due to the presence of the hulls, 22% from the seeds and 53% of the kernel, and also the crude protein content was so high as the 21.8% of the seeds.

The seed oil from a local variety Rubus idaeus L. (family Rosaceae) was isolated and the physical and chemical characteristics were determined. The oil content of Rubus idaeus seeds ranged from 8-15%. Standard procedures were applied to determine specific gravity, refractive index, acid value, saponification value, iodine value and peroxide value.
