  Oil were extracted from seeds of the Nigerian plants Pentaclethra macrophylla, Treculia africana, persea gratesima and Telferia occidentalis using n-hexane and their physicochemical properties compared with oils from seed of Cocos nucifera. Percentage oil yield were 20.80, 18.00, 14.00, 18.00 for P. macrophylla. T. africana, P. gratesima and T. occidentalis respectively while the value for C. nucifera seed oil is 32.00. All the five seed oil were odourless and at room temperature liquids. Specific gravity of the seed oils ranged from 0.81-0.90 while peroxide value for all the oil seed were less than 6.00. Saponification values were as low as 106.60 in P. gratesima and as high as 246.00 in C. nucifera seed oils. Iodine values were between 9.60 and 52.40 in the extracts. These results suggest that oil seeds examined may be viable source of oil going by their oil yield. The studied characteristics of all oil extracts in most cases compared favourably with C. nucifera seed oil which is presently used for both domestic and industrial purposes in Nigeria.

  The nutritional potential of the leaves and seeds of Solanum nigrum L. Var virginicum was assessed by determining proximate and phytochemical composition. Results indicate protein content of the leaves and seed as 24.90% and 17.63% respectively. Other findings are ash 10.18% and 8.05%, crude fibre, 6.81% and 6.29 and carbohydrate, 53.51 and 55.85% for the leaves and seed respectively. Mineral analysis revealed the order Mg>K>Ca>Fe>Na>Mn>Zn in the leaves and Mg>K>Fe>Ca>Na>Mn>Zn in the seeds. Phosphorus and sulphur levels were 75.22 and 8.55 mg/100g in the leaves and 62.50 and 14.48, g/100g in the seeds. Vitamin content indicate the order vit C>vit B,>Folic acid>Vit E>Vit A in both the leaves and seeds. Phytochemical analysis revealed high oxalate, phenol but low sterol content in the studied plant materials. Cyanide levels were higher in the leaves compared to the seeds. These results suggest that S. nigrum L. Var virginicum to be nutritive despite the presence of some anti-nutritive components like oxalate.
