Bioactive and radioactive properties of some edible wild Lactarius mushrooms

Abstract

Bioactive and radioactive properties of Lactarius delicious, Lactarius insulsus, Lactarius vellereus mushrooms were investigated and for this purpose, protein and total phenolic substance amounts, antioxidant and antimicrobial properties of mushrooms collected from Kastamonu province were determined. In addition, the amounts of some trace elements (Mg, Al, Ca, Mn, Fe, Co, Ni, Cu, Zn, Se, As, Cr, Cd) in mushrooms, three isotopes of lead (206Pb, 207Pb and 208Pb), natural (238U, 232Th) 40K) and artificial radionuclide (137Cs) levels were also calculated. Among the fungi; L. delicious attracted attention with its higher protein content and accumulation of Mg, Ca, Mn, Fe, Co, Ni, Zn, Pb-206, Pb-208, Cr. The highest total phenolic content and antioxidant activity were found in L. vellereus. Additionally; the highest 232Th and 40K radionuclide content was also determined in L. vellereus. Artificial radionuclide (137Cs) was observed only in L. insulsus fungus. As a result, it was concluded that the differences between mushroom species may affect the results of the analysis, although they are of the same genus and collected from the same region.
