Özet

In this study, antiradical and antimicrobial activity, total phenolic, mineral and heavy metal content of Morchella conica Pers. were determined in the methanolic extracts of dried M. conica collected from wild-grown edible mushroom in the Mediterranean region from Turkey. Free radical scavenging activity was determined to be 43.72 +/- A 0.13% DPPH decoloration, however, total phenolic activity to be 20.64 +/- A 0.33 mg GAE/g dry ext. sample. The antimicrobial activity of the extracts was tested against fourteen microorganism including 12 bacteria and 2 yeasts. It was determined that the mushroom extracts had no effect against the bacteria and yeasts. Antimicrobial effect was determined only against Staphylococcus aureus ATCC 29213. M. conica was determined to contain some heavy metals such as arsenic (As), mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr) and nickel (Ni) in the concentrations of 0.25, 0.06, 0.20, 1.20, 0.70 and 1.10 (mg/kg dw), respectively. Potassium (K), phosphorus (P) and magnesium (Mg) contents were determined to be 20,400, 13,250, and 1,600 (mg/kg dw), respectively, being higher than those of the other minerals in the M. conica extracts.
