• Protein-energy malnutrition (PEM) usually occurs in combination with deficiencies in essential micronutrients, specifically vitamin A, vitamin B6, folate, vitamin E, zinc, iron, copper, and selenium.
• Anthocyanins bind transition metals such as iron and copper, inhibiting hydroxyl radical production mediated by the Fenton process and safeguarding biological components against oxidative changes.
• Brassica plants grown under a red-to-blue light ratio of 4:1 show accumulation of iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
• Phosphorus in a plant digest is analyzed using the Canada-molybdate yellow color method, Potassium and Calcium are analyzed using a flame photometer, Sulfur is evaluated using a turbidimetric process, and Sodium, Zinc, Copper, Iron, and Manganese are determined using atomic absorption spectrophotometry.
• The StatPearls article 'Wound Healing Phases' cites research covering diverse topics including tissue concentrations of minerals (zinc, iron, copper, magnesium), morphoelastic models for dermal closure, urological wound healing, chronic wound treatment patents, wound irrigation methods (tap water vs. sterile saline), the role of Vitamin C, sonic hedgehog gene therapy, and low-level laser therapy for burn and gingivectomy wounds.
• Lettuce plants grown under red light show accumulation of potassium (K), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
• Dried Vernonia amygdalina leaves have higher calcium and iron content, while fresh leaves have higher magnesium, copper, and lead content.
• Pyne and Santra (2017) documented the accumulation of arsenic, copper, and iron in common medicinal plants found in the Murshidabad district of West Bengal, India, published in the International Journal of Experimental Research and Review.
• Mustard plants grown under a blue-to-red light ratio of 1:1 show accumulation of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), and boron (B).
• Rybicka and Gliszczyńska-Świgło analyzed the content of calcium, potassium, magnesium, sodium, copper, iron, manganese, and zinc in grain gluten-free products in a 2017 study.
• Mineral analysis of medicinal plants determines the presence of essential elements including sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
