Impact of plant domestication on selected nutrient and anti-nutrient compounds in Solanaceae with edible leaves (Solanum spp.)

Abstract

Several 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.

Polyphenols and ω-3 PUFAs: Beneficial Outcomes to Obesity and Its Related Metabolic Diseases

“…The main sources of ω-3 PUFAs, including ALA, EPA and DHA are green leafy vegetables, seaweed, seeds, nuts, vegetable oils, fish and fish oils (68)(69)(70)(71)(72)(73)(74)(75)(76)(77). The vegetable and fish origin ω-3 PUFAs are summarized in Table 3.…”

“…ALA is abundantly obtained in vegetable foodstuff and microalgae (7-94%) followed by vegetable oils (6-58%) and freshwater fish (1-4%) (69,70,(73)(74)(75)(76)(77). While EPA and DHA are the majority in fish oil (7-13% and 9-18%), marine fish (3-6% and 13-33%), microalgae (13-31% and 2-14%), macroalgae (3-27% and 1-5%), and fish of freshwater (0.4-3% and 2-9%) (69,(71)(72)(73)(74)76).…”

Effect of Brine fermented Pickling to Physicochemical, Anti-nutritional, and Microbiological Attributes of Pickled gboma Eggplant (Solanum macrocarpon)

“…The fruit included numerous seeds and it's partly filled by the calyx lobes. 1 It could be eaten raw, boiled, fried, stewed, or sauced. Gboma eggplant could be utilized for obesity prevention as well as limitation of numerous ailments.…”
