Abstract

Chemical analyses were carried out to determine the nutritional and phytochemical constituents of fruits of two indigenous Africa eggplants, S. aethiopicum L. and S. macrocarpon L. Proximate analysis of fresh fruits of S. aethiopicum L. (per 100 g) showed: 89.27 ± 0.12 g moisture, 2.24 ± 0.03 g protein, 0.52 ± 0.04 g fat, 0.87 ± 0.03 g ash, 2.96 ± 0.08 g crude fiber, 4.14 ± 0.11 g carbohydrate and 498.47 ± 2.14 mg calcium, 1.98 ± 0.10 mg magnesium and 1.02 ± 0.02 mg iron. Fresh fruits of S. macrocarpon L. contained (per 100 g): 92.50 ± 0.14 g moisture, 1.33 ± 0.05 g protein, 0.17 ± 0.01 g fat, 0.47 ± 0.02 g ash, 1.11 ± 0.03 g crude fiber, 4.42 ± 0.12 g carbohydrate, 101.56 ± 1.21 mg calcium, 1.01 ± 0.08 mg magnesium and 0.70 ± 0.01 mg iron. There was a significant presence of alkaloids, saponins, flavonoids, tannins and ascorbic acid in both fruits; terpenoids was found in trace amount. Steroids were present in S. aethiopicum L. and absent in S. macrocarpon L. These phytochemicals are of therapeutic importance; their presence in S. aethiopicum and S. macrocarpon fruits indicate the beneficial effects of the plants. Solanum aethiopicum L. contained higher levels of the beneficial agents than S. macrocarpon L. The two indigenous eggplants are not only nutritionally and therapeutically valuable, but also have the potential of providing precursors for the synthesis of useful drugs.
