The aim of this work is to obtain some carotenoidic extracts from peach (Persica vulgaris) pulp and pericarp, Red haven variety, and to determine by reverse phase- high pression liquid chromatography (HPLC) the content of β-carotene and total carotenoids. Also, were determined by atomic absorption spectrometry, 12 mineral elements (K, Na, Ca, Mg, Fe, Mn, Cu, Zn, Pb, Co, Cr, Ni) of raw materials and carotenoidic extracts obtained. The results showed that the peach pericarp are richer in β-carotene and total carotenoids than peach pulp. All macroelements from carotenoidic extracts are found in much lower concentrations than in raw materials. Concentrations of Na, Ca, Mg, Zn and Pb in the peach pulp and in the peach pulp extract are lower than the concentrations of these elements in the peach pericarp, respectively in the peach pericarp carotenoidic extract. Fe, Cu, Cr and Ni, however, are better represented in the peach pulp, respectively in the carotenoidic extract from it. Mn and Co are not present either in raw materials and in carotenoidic extracts.
