  Abstract:  The study refers to the content determination of calcium, magnesium and polyphenols in hawthorn fruits collected from Vulcan coal dump. This dump was never covered by fertile soil or fertilizer containing nitrogen, potassium and phosphorus. The hawthorn fruits obtained from dump contains significantly high concentration of calcium and magnesium, compared with the already published data. The polyphenols were evaluated by spectral (UV-Vis spectrophotometry) and chromatographic (TLC and HPLC) methods. The total flavonoids and total polyphenols contents of dump fruits are similar with those obtained in fruits collected from hawthorn culture, being lower than the already published data. In both type of hawthorn fruits could be identified the hyperoside, as the main flavonoid. We found also rutoside, only in traces, in the culture sample.

Keywords: coal dump, hawthorn fruits, calcium, magnesium, polyphenols.
