Preliminary study on trace metal content in manna extracted from Fraxinus angustifolia cultivars in Madonie (Sicily, Italy)

2019

The manna is a product obtained from the elaborate sap solidification that comes out from the incisions made on the stem of some species of the genus Fraxinus L. In this study, we have analyzed 12 samples of manna to determine the chemical composition. Twenty elements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, U, V, Zn) were determined using an Inductively Coupled Plasma Mass Spectrometer. The results show that the most abundant elements are Fe > Rb > Al > Cu > Ba > Zn > Sr with median concentrations in the range of 0.9 – 10mg kg-1. The remaining elements exhibit median concentrations in the range of 0.0003 -0.5 mg kg-1. The manna also can be cons…
