- Leafy vegetables including Amaranthus graecizans, Portulaca oleracea, and Solanum nigrum are good sources of protein and minerals, specifically calcium (Ca), iron (Fe), and zinc (Zn).
- Uddin et al. (2012) reported that mature leaves of Portulaca oleracea contain high amounts of calcium, iron, and zinc. Wenzel et al. (1990) further identified that Portulaca oleracea shoots are abundant in omega-3 fatty acid, α-tocopherol, ascorbic acid, β-carotene, and glutathione, making the plant a source of minerals, vitamins, and antioxidants for functional foods and nutraceutical applications.
- Amaranthus graecizans, Portulaca oleracea, and Dioscorea cayenensis are identified as notable sources of calcium, iron, and zinc, while the fruit Rubus apetalus is a notable source of provitamin A.
- Rumex apetalus and Portulaca oleracea contain 6.51 mg/100 g and 4.33 mg/100 g dry edible portion of zinc, respectively.
- Portulaca oleracea is considered a weed in Ethiopia, but its leaves and stems contain high amounts of iron, zinc, and vitamin C, including twice the amount of iron found in maize.
