Wild indigenous vegetables have recently been receiving attention due to their accessibility and potential to fight malnutrition. The current study investigated the nutritional profile of 10 selected wild indigenous vegetables, namely , , , , , , , , , and , consumed by the Basotho people of southern Africa. This was done by first compiling a comprehensive literature review to identify the knowledge gaps and further analysing the selected vegetables for mineral contents and proximate compositions using standard analytical procedures of AOAC. The literature survey revealed that 90 wild plants are used as vegetables by the Basotho people, and there are knowledge gaps on the nutritional value of many species. Mineral analyses of the wild vegetables showed that and are rich in minerals such as Al, Ca, K, Mg, Na, P, and S and can compete favourably with commercialised vegetables such as lettuce and spinach in terms of mineral components. Also, all the wild vegetables studied have more than 12% recommended caloric protein value except (10.07%) and (11.32%). The crude fat content in , , , , and fall within the range required for healthy living. The concentrations of cadmium, copper, and lead in all the vegetables studied are below the detection level, thus making them non-toxic and safe for consumption.
野生本土蔬菜因其易获取性和对抗营养不良的潜力，近来受到了关注。当前研究调查了10种选定的野生本土蔬菜的营养成分，这些蔬菜为南部非洲巴索托人所食用，分别是 ， ， ， ， ， ， ， ， ，以及 。研究首先通过编撰一份全面的文献综述来找出知识空白，然后使用美国官方分析化学家协会（AOAC）的标准分析程序，对选定的蔬菜进行矿物质含量和近似成分分析。文献调查显示，巴索托人将90种野生植物用作蔬菜，许多物种的营养价值存在知识空白。对野生蔬菜的矿物质分析表明， 和 富含铝、钙、钾、镁、钠、磷和硫等矿物质，在矿物质成分方面可与商业化蔬菜如生菜和菠菜相媲美。此外，除了 （10.07%）和 （11.32%）之外，所有研究的野生蔬菜的推荐热量蛋白值均超过12%。 、 、 、 和 中的粗脂肪含量处于健康生活所需的范围内。所有研究蔬菜中的镉、铜和铅浓度均低于检测水平，因此它们无毒且食用安全。
