 Deciduous tree, up to 20-25m tall, native to the tropical Africa (savanna), cultivated also as ornamental and for food; crown rounded, ĺeaves palmately divided, 3-7 leaflets, mostly 5 with the lower leaflets distinctly smaller; leaflets obovate, leathery, dark green above, paler below; flowers blue, violet or white, the lower lobe darker; fruit ellipsoid, fleshy, hairless, purple-black, edible (used as food, tasting a bit like prunes -  hence the name). \\ Deciduous tree, up to 20-25m tall, native to the tropical Africa (savanna), cultivated also as ornamental and for food; crown rounded, ĺeaves palmately divided, 3-7 leaflets, mostly 5 with the lower leaflets distinctly smaller; leaflets obovate, leathery, dark green above, paler below; flowers blue, violet or white, the lower lobe darker; fruit ellipsoid, fleshy, hairless, purple-black, edible (used as food, tasting a bit like prunes -  hence the name). \\

 "A comparative analysis of the aroma potencies of the free and bound volatile fractions revealed that; free fraction exhibited strong potency for the fruity and floral notes, and the bound fraction produced more of the flowery, caramel-like and cherry-like notes. In addition results of odour activity values showed that ethylbutanoate, β-damascenone, ethyl-2-methyl propionate, linalool, hexyl acetate and (Z)-rose oxide contributed highly to the sweet prune-like aroma of the fruit... \\ "A comparative analysis of the aroma potencies of the free and bound volatile fractions revealed that; free fraction exhibited strong potency for the fruity and floral notes, and the bound fraction produced more of the flowery, caramel-like and cherry-like notes.
