AbstractSeveral African Solanum species, including scarlet eggplant (Solanum aethiopicum L.) and the gboma eggplant (S. macrocarpon L.), are recently domesticated green leafy vegetables. The aim of the study was to determine if domestication process affected the amounts of selected nutrient and antinutrient compounds in plant lines bearing edible and inedible leaves in comparison to their wild relatives. Leaves from fourteen accessions of five Solanum species were evaluated for phenolics (385–1002 mg gallic acid equivalent/100 g dry weight), fatty acid (0.9–3.2 g/100 g DW), sterol (32–99 mg/100 g DW), saponin and glycoalkaloid content (0–1000 mg and 0–55 mg/100 g DW, respectively, expressed as aglycone content). There were no significant differences between plants with edible and inedible leaves. Similarly, wild and domesticated plants produced comparable amounts of nutrient and anti-nutrient compounds, with exception of wild S. anguivi Lam., which displayed fatty acid content higher than other species. The gboma eggplant complex (S. macrocarpon– S. dasyphyllum Schum. et Thonn.) had lower anti-nutrient and phenolics content than scarlet eggplant (S. aethiopicum–S. anguivi). Semi-domesticated S. scabrum Mill. revealed high anti-nutrient and low nutrient production. Selection based on plant morphology is then suggested as the dominating mechanism at the early stage of domestication of African solanaceous plants.
