Abstract
The aim of this work was to study the content of Fe, Mn, Zn and Cu in the mixtures which contain volatile oils among other components, obtained after the Soxhlet extraction, maceration or ultrasonic technique of the samples and in the fresh fruits (Malus domestica and Cydonia oblonga). Both fruits belong to the same family named Rosaceae. subfamily Maloideae (or Pomoideae) whose fruits consist of five capsules (called "cores") in a fleshy endocarp, surrounded by the ripened stem tissue. Flame atomic absorption spectrometry (FAAS) was used for the quantitative determination of metals in these matrixes and fruits (dry weight). Also, the refraction indices and conductivity were measured using Abbe refractometer and LF 340-A conductometer, for the characterization of the obtained mixtures, respectively for correlation with the mineral content. It was observed that iron concentrations are in higher quantities than Mn, Zn and Cu in both studied fruits.
