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 different mushroom species have different bioactive and radioactive properties, although they are of the same genus and collected from the same region.

Bazı yenilebilir yabani Lactarius mantarlarının biyoaktif ve radyoaktif özellikleri

Abstract

Lactarius delicious, Lactarius insulsus, Lactarius vellereus mantarlarının biyoaktif ve radyoaktif özellikleri araştırılmıştır ve bu amaçla Kastamonu ilinden toplanan mantarların protein ve toplam fenolik madde miktarları, antioksidan ve antimikrobiyal özellikleri belirlenmiştir. Ayrıca mantarlardaki bazı eser element (Mg, Al, Ca, Mn, Fe, Co, Ni, Cu, Zn, Se, As, Cr, Cd) miktarları, kurşunun üç izotopu (206Pb, 207Pb and 208Pb), doğal (238U, 232Th 40K) ve yapay radyonüklit (137Cs) seviyeleri de hesaplanmıştır. Mantarlar arasında; L. delicious, daha yüksek protein içeriği ve Mg, Ca, Mn, Fe, Co, Ni, Zn, Pb-206, Pb-208, Cr birikimleriyle dikkat çekmiştir. En yüksek toplam fenolik içerik ve antioksidan aktivite L. vellereus’da bulunmuştur. Bunlara ek olarak; en yüksek 232Th ve 40K radyonüklid içeriği de L. vellereus’ta belirlenmiştir. Yapay radyonüklid (137Cs) sadece L. insulsus mantarında gözlenmiştir. Sonuç olarak, aynı cinsten olmalarına ve aynı bölgeden toplanmalarına rağmen farklı mantar türlerinin farklı biyoaktif ve radyoaktif özelliklere sahip olduğu görülmüştür.
