Abstract: Proximate, mineral and selected physicochemical characteristics of baobab (Adansonia digitata) Seed - oil were determined using standard analytical methods. The proximate composition (%) of the seeds were as follows; moisture (3.5 ± 0.1), crude protein (12.9 ± 0.015), crude lipid (14.3 ± 0.05), ash (4.49 ± 0.05), crude fiber (20.42 ± 0.04) and carbohydrate (44.32 ± 0.25). The major mineral elements present in the seeds included phosphorus, calcium, potassium, zinc and iron (7.00, 9.61, 90.29, 0.268, and 0.227 ppm respectively). Vitamin C was found in baobab seeds with concentration = 70.9 mg/100g. The oil extracted from the seed had the following physicochemical properties: oil content 21.5 ± 0.00%, density 0.09154, specific gravity 0.9163, kinematic viscosity 33.69 cSt, calorific value 43.797Mg kg-1 cloud point +9, pour point -3, acid value, 1.7 ± 0.119 mg KOH g-1, saponification value 275.05 ± 0.52 mgKOH g-1, free fatty acid 3.8, peroxide value 7.6 ± 0.05 mEq kg-1, and The iodine value (54 ± 0.1 mg g-1). According to above result, baobab seeds could have a high potential uses.
