Zusammenfassung:The research presents analytical data on three varieties of a commonly consumed vegetable, Lesianthera africana, in southern Nigeria. The Etoi (bitter) variety seemed to possess the best (p < or = 0.01) nutritional value (highest lipid, protein, calories, iron, calcium, phosphorus, least fiber) but highest toxic components (mg/100 g: 1.62 HCN; 17.6 oxalate; 1630 glucosinolates), which are far below toxic limits. The Ikot Abasi (riverine) variety was found to be highly (p < or = 0.01) fibrous (18.1 mg/100 g dry matter) but low in micronutrient minerals. The Etinan (flavorful) variety was found to be moderately nutritious. The findings are discussed in relation to nutrient interactions and recommendations are made regarding dietetic use.
