Contents of metals in some wild mushrooms : Its impact in human health

The concentrations of 7 metals (lead, cadmium, manganese, copper, nickel, silver, and chromium) were determined in 32 different species of wild mushrooms. The mushroom samples, which have been using for food and some medical purposes, were collected from Konya, an Inner Anatolian region of Turkey. The highest metal concentrations were determined as 39 mg/kg Pb and 3.72 mg/kg Cd in Trichaptum abietinum 467 mg/kg Mn in Panaeolus sphinctrinus, 326 mg/kg Cu in Trametes versicolor, 69.4 mg/kg Ni in Helvella spadicea, 6.97 mg/kg Ag in Agaricus campestris, and 84.5 mg/kg Cr in Phellinus igniarius. The maximum contents are 1.52, 2.22, and 60.2 mg/kg in Pleurotus eryngii (for Pb), Amanita vaginata (for Cd), and Helvella leucomelana (for Cu), respectively. These results were compared according to the WHO/FAO standard.

Inhibitory Effect of Essential Oils of Myrtle, Laurel, Pickling Herb and Thyme and Savory on the Mycelial Growth of Agaricus Campestris (Lange) Sing

Abstract The effect of different oil levels of myrtle (Myrtus communis L), laurel (Laurus nobilis L.), pickling herb (Echinophora tenuifolia L. subsp. sibthorpiana (Guss.) tutin), thyme (Thymbra spicata L.) and savory (Satureja hortensis L.) which grow wild in Turkey were investigated on the mycelial growth of Agaricus campestris in vitro. The results showed that all concentrations of thyme ans savory showed a strong inhibitory effect on mycelial growth. The levels of 5μl of pickling herb, 5 μl and 15 μl of laurel, and 5 μl level of myrtle oils, respectively, showed inhibitory effect according to until 26, 11, 18 and 4 days of incubation while 25 μl levels of all herb oils showed a stronger inhibitory effect. As a result, the effectivenes of the inhibitors followed the sequence: thyme=savory > pickiling herb > myrtle > laurel herb

Effect of Essential Oils of Some Plants Used as Herb on the Growth of Agaricus bisporus (Lange) Sing

Abstract Essential oils at the concentration of 5 ul, 15 ul and 25 \ûof Myrtus communis L., Laurus nobilis L., Echinophora tenuifolia L., Thymbra spicata L. and Satureja hortensis L., which grow wild in Turkey were prepared and investigated for growth of Agaricus bisporus in culture media. The results showed that 25 ul concentration of essential oils showed an inhibitory effect on mycelial growth. Other concentrations of oils partly inhibited the growth of A bisporus. The mycelial growth of all samples treated had slow and different according to control group. It was observed a slow growth in sample with thyme (black), while myrtle and thyme (savory) oils exhibited fungisit effect against A. bisporus, others had fungistatic effect.
