This paper presents the nutritionally essential macro (Ca, K, Mg, Na, P) and micro (Fe, Mn, Cu, Zn) minerals contents of fifteen selected leafy wild and semi-wild food plants (WSWFPs) from Bunyoro-Kitara Kingdom, Uganda. All the mineral assay were conducted using standard procedures. The results of the analyses were compared those of the conventionally well known and widely cultivated Brassica oleracea var capitata. L. (Alef.) - the common cabbage plant. Compared to the conventionally planted cabbage, most analysed WSWFPs were generally richer sources of macro and micro mineral elements. Ca contents were richer (373.50–518.43 mg/100g) in Asystasia mysorensis, Asystasia gangetica, Acalypha bipartita,Amaranthus spinosus, Bidens pilosa, Senna obtusifolia, Solanum nigrum, and Cleome hirta. While K concentrations were highest (365.64–714.14 mg/100g) in Amaranthus spinosus, Sonchus oleraceus, Basella alba, Asystasia gangetica, Asystasia mysorensis and Cleome hirta. Mg content was more abundant (235.90–421.70 mg/100g) in Asystasia gangetica, Asystasia mysorensis, Bidens pilosa, Senna obtusifolia, and Solanum nigrum. Na content was highest (234.15–355.75 mg/100g) in Senna obtusifolia, Bidens pilosa, Vernonia amygdalina, and Sonchus oleraceus. P was more abound (237.78–505.38 mg/100g) in Asystasia gangetica, Bidens pilosa, Asystasia mysorensis, and Senna obtusifolia. Fe content was highest (10.77–30.03 mg/100g) in Acalypha bipartita, Corchorus trilocularis, Asystasia gangetica, Bidens pilosa, Asystasia mysorensis, Senna obtusifolia, and Vernonia amygdalina. Mn was more plentiful (5.74–32.75 mg/100) in Vernonia amygdalina, Asystasia mysorensis, Asystasia gangetica, Bidens pilosa, Cleome hirta and Senna obtusifolia. Cu content was more concentrated (2.32–8.81 mg/100g) in Bidens pilosa, Vernonia amygdalina, Asystasia mysorensis, Asystasia gangetica, and Senna obtusifolia. Zn was more abundant (6.48–11.43 mg/100g) in Senna obtusifolia, Bidens pilosa, Vernonia amygdalina, Asystasia gangetica, Amaranthus spinosus and Asystasia mysorensis. These findings therefore suggest that a routine diet comprising of WSWFPs can definitely assure a relief from some of the major and minor mineral deficiencies often faced by the poor households.
