Abstract

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.

摘要

该研究展示了尼日利亚南部一种常见食用蔬菜——非洲莱斯安瑟拉（Lesianthera africana）三个品种的分析数据。埃托伊（苦味）品种似乎具有最佳（p≤0.01）营养价值（脂质、蛋白质、卡路里、铁、钙、磷含量最高，纤维含量最低），但有毒成分含量也最高（每100克中含1.62毫克氢氰酸；17.6毫克草酸盐；1630毫克硫代葡萄糖苷），不过这些含量远低于毒性限值。伊科特阿巴西（河滨）品种纤维含量很高（p≤0.01，干物质中每100克含18.1毫克），但微量营养素矿物质含量低。埃蒂南（美味）品种营养程度适中。文中结合营养相互作用对研究结果进行了讨论，并就饮食用途提出了建议。
