Abstract

Baobab (Adansonia digitata) leaves are usually used in dry form in the preparation of a soup known as ‘miyan kuka’ in Northern Nigeria. The leaves are believed to have nutritional and medicinal benefits and have been used for those purposes in Africa and Asia. However there has been limited research on the detailed constituents of the dry leaves. In this study, phytochemical, elemental and proximate analyses of stored, sun and shade-dried baobab leaves were conducted. The results revealed a great variation in the nutritional contents of the leaves. The study reveals that the leaves are rich in phytochemicals such as glycosides, saponins, steroids and flavonoids while alkaloids, tannins and resins are absent. Also, they are important source of minerals such as zinc, copper, iron and manganese. In addition, they are rich in fibre, crude protein, nitrogen and ash. Contrasting responses were obtained in the samples studied. The implications of these responses are discussed in relation to crop yield.
