In this work Pleurotus ostreatus, Agaricus bisporus and Lactarius delicious were used to
determine and compare their antioxidant capacities and metal contents. The
edible mushroom samples were collected from Kastamonu in the West Black Sea
region of Turkey. The antioxidant capacity studies were performed by DPPH (1,
1diphenyl-2-picryl hydrazyl) radical scavenging method and were expressed as
Trolox equivalents with spectroscopic measurements. TEAC (Trolox Equivalent Antioxidant Capacity)
values were found 0.302, 0.557 and 0.251 µM/g for Pleurotus
ostreatus, Lactarius delicious
and Agaricus bisporus, respectively.
All samples were analyzed by X-ray fluorescence (XRF) spectrometry to obtain
the concentration of Cr, Mn, Fe, Ni, Cu, Zn, Ca, Pb, Na, Mg and K. While
maximum and minumum metal contents of mushrooms were found as mg/g for Na
(96-14.9), Mg (8.83-2.60), K (4.05-3.16), Ca (0.089-0.019) and Fe
(0.128-0.099), the maximum and minumum contents of mushrooms were found for Cr
(8-5), Mn (12-11), Ni (15-6), Cu (30-20), Zn (7-3) and Pb (3-1) as mg/kg. Metal contents were
determined together with antioxidant capacity of all analysed mushrooms. It was observed that although the Fe, Ni, Ca, Na, and
Mg contents of Agaricus bisporus were lower, it had got higher inhibition than the
other mushroom species.
