“…In the leaves of the common dandelion Taraxacum officinale, the Ca:Mg ratio is 2.79:1, while in the leaves of sea buckthorn Hippophae rhamnoides, it is 1.14:1 [36]. The Ca:Mg ratio in hair is 3-11:1 [37].…”

“…In the leaves of the common dandelion Taraxacum officinale, the Ca:P ratio was 1.31:1 [36], while in the leaves of the sea buckthorn Hippophae rhamnoides, it was only 0.61:1. In the hair of healthy women, the ratio ranged from 1.6 to 3.6:1 [37]. Of course, the quoted proportions in human hair cannot be directly compared, but analysis of the mineral composition of hair is an excellent tool in assessing the nutritional balance.…”

In this study, leaf extracts from the Green Globe cultivar of artichoke (Cynara scolymus L.), a herbaceous plant of the Asteraceae family, were analyzed to determine the levels of basic nutrients, selected macroelements (K, P, Ca, Mg, and Na) and microelements (Zn, Fe, Mn, Cr, Pb, Cd, and Ni), and their ratios. The antioxidant activity (aa) of the extract was evaluated using ABTS˙+ and DPPH˙+ radicals and the ferric reducing antioxidant power assay (III) (FRAP). Total polyphenolic content was also determined. Macroelement concentrations in the artichoke leaf extract can be presented in descending order as follows: K > P > Ca > Mg > Na. Microelement content in the extract was as follows: Zn > Fe > Cr > Mn. We determined the ratios of elements in artichoke leaf extracts and compared them against the recommended dietary allowance, adequate intake, or tolerable upper intake level. Mean total phenolic content in artichoke leaf extracts was high-2795 mg CAE/100 g dry matter (DM). The ABTS˙+ assay showed a very high ability of artichoke extract to scavenge free radicals (79.74%), and the antioxidant capacity measured at 1060.8 Trolox/1 g DM. The results show that artichoke extract is a valuable source of minerals and antioxidants that could have applications in the prevention of chronic non-communicable diseases caused by oxidative damage.
