The influence of magnesium and manganese cations on the chemical and bioactive properties of purple and green basil.

This research investigated the effects of hydroponic cultivation with enriched concentrations of magnesium (+Mg), manganese (+Mn), a combination of +Mg and +Mn, or decreased concentrations of these minerals (control) on the nutritional, chemical, and bioactive attributes of purple and green basil. While Mn significantly increased the growth of purple basil and affected the composition of essential oil and mineral accumulation, plants treated with Mg showed alterations in nutrient absorption. Protein values were lower, indicating suboptimal protein synthesis, but significant increases were observed in fat, ash, and carbohydrates, suggesting a more nutrient-rich composition due to hydroponic cultivation.
