“…Moringa leaf extract contains high levels of plant growth hormones, antioxidants, vitamins, secondary metabolites, and minerals (Table 1) [22][23][24]. Growth hormones such as gibberellins, indole-3-acetic acid (IAA), abscisic acid (ABA), salicylic acid (SA), and cytokinins, minerals such as sodium (Na + ), potassium (K + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), zinc (Zn 2+ ), iron (Fe 3+ ), and manganese (Mn 2+ ), more than 40 natural antioxidants such as ascorbic acid (ASC), glutathione (GSH), β-carotene, tocopherols, vitamins A, B, C, D, and K, and many secondary metabolites occur at high levels in MLE [16,20,[25][26][27][28][29][30][31][32][33][34]. Of particular note, plant growth-regulating cytokinins are present in the forms of zeatin, dihydrozeatin and isopentyladenine [35,36].…”
