The aim of the present study was to analyze and compare contents of copper, zinc and chromium in 15 kinds of wild mushrooms. heavy metals were determined using flame atomic adsorption spectrometry (VARIAN, SpectrAA-220Fs). The mushrooms were collected from Miyi, China. The study explored the accumulation of heavy metals in different macrofung. Minimal and maximal concentrations of heavy metals were determined in Termitomyces microcarpus and Amanita esculenta for copper, Ramaria flava and Termitomyces for zinc, Hygrophorus eburnesus and Boletus aereus for chromium ,respectively. chromium values in wild mushrooms collected from Miyi were generally higher than the previous studies. Copper and zinc contents were in agreement with the literature value.

Two heavy metals (nickel and cadmium ) in 15 specis of wild mushrooms were determined using flame atomic adsorption spectrometry (VARIAN, SpectrAA-220Fs). The mushrooms were collected from Miyi, China. The study explored the accumulation of heavy metals in different macrofung. It is found that the range of Nickel and Cadmium in mushrooms were 1.78-21.22 mg/kg and 0.47-21.84 mg/kg. Minimal and maximal concentrations of heavy metals were determined in Lentinus edodes and Boletus edulis for nickel, Russula alutacea and Russula delica for cadmium,respectively. The order of the levels of heavy metals in the mushrooms samples was found to be as Ni>Cd. Cadmium values in wild mushrooms collected from Miyi were generally higher than the previous studies. Nickel contents were in agreement with the literature value.

Studies to exploit wild mushrooms as a source of biologically active compounds are gaining importance in the recent years. In that view, the present study was carried out to evaluate the bioactive compounds of six wild edible mushrooms: Lentinus squarrosulus Mont., Auricularia auricular-judae (Bull.) Wettst., Mycetinis copelandii (Desjardin) A.W. Wilson & Desjardin, Baeospora myosura (Fr.) Singer, Pleurotus ostreatus (Jacq. ex. fr) Kummer and Volvariella volvacea (Bull. ex. Fr.) Singer. The specimen was subjected to phytochemical screening using gas chromatography mass spectrometer (GCMS) with the view to identify the important volatile constituents. The dried sporocarp was subjected to methanol extraction using a Soxhlet extractor and rotatory evaporator. This led to the identification of 14, 26, 33, 5, 49 and 32 different compounds in L. squarrosulus, A. auricular-judae, M. copelandii, B. myosura, P. ostreatus and V. volvacea respectively. n-Hexadecanoic acid; 9,12-Octadecadienoic acid (Z,Z)- and 2(3H)-Furanone where the most frequently occurring compounds across the studied mushrooms. The identified compound reportedly shows diverse bioactive activities, including antiviral, anticancer, antimicrobial, antioxidant, hypocholesterolemic, anaphylactic, narcotic, neurostimulant, emollient, expectorant, laxative, pesticidal, insecticidal and insectifugal activities. This data may provide baseline information about the bioactive constituents of these species from Nigeria, in providing valuable compounds of substantial medicinal and agricultural importance.

Background: The continuous worldwide increase of consumption of fresh mushrooms has registered in the recent years. The major goal of this study was to determine the microbiological characteristics of wild edible mushrooms and effect of temperature during storage of Morchella conica. Methods: Wild mushrooms of the species Boletus edulis, Cantharellus cibarius, and Leccinum aurantiacum were collected in a mixed forest of Picea abies, Betula pendula, and Pinus sylvestris located in Tartu territory, Estonia. Faecal indicators, potential pathogens, spoilage bacteria, and microfungi (yeasts and moulds) were evaluated. M. conica was microbiologically investigated for 24 days under different thermal regimes, including 4, 8, 12, 15, 20, and 28 °C. The statistical analysis was conducted with SAS 9.2 software. Results: The microbial counts of wild mushrooms, ranging from 6.81 to 7.68 log10 CFU/g for total mesophilic count, were generally higher (p<0.05) than those registered for marketed samples ranging from 4.60 to 7.39 log10 CFU/g. The dynamics of total mesophilic microorganisms on M. conica stored at different temperatures indicated that stationary and death phases occurred earlier with increasing temperature and that the highest levels were registered at 28 °C at the 2nd day of storage. Conclusion: This work highlights consistent differences in terms of microbiological properties among different mushrooms species. The results clearly showed that total mesophilic populations developed at high levels quickly at temperatures more than 15 °C, but also the refrigeration did not stop the microbiological decay of mushrooms.

Contamination of the food chain with heavy metals has become an urgent problem in recent years due to their potential accumulation in biosystems and is related to increased anthropogenic impact. This study assessed the levels of cadmium, lead, copper and zinc in cattle from the Novosibirsk, Krasnozersk, and Maslyanino regions of the Novosibirsk region and the Tselinny region of the Altai region. The aim of the study is to assess the influence of the ecological and geographical factors on the content of heavy metals in the spleen of Hereford gobies. Spleen samples were taken from 31 clinically healthy Hereford bulls aged 16-18 months. Sample preparation was carried out in accordance with GOST 26929-94 and 30178- 96. The determination of the chemical composition of the samples was carried out by atomic absorption spectrometry with flame and electrothermal atomization. The median values for the content of copper, zinc, lead and cadmium in the spleen of bull calves bred in Krasnozersky, Maslyaninsky, Novosibirsk and Tselinny regions were in the range of 1.6-1.8; 21.0-22.4; 0.06-1.45; 0.01-0.09 mg / kg. The phenotypic variability of the level of copper and zinc was relatively low, while that of lead and cadmium was high. The influence of the ecological and geographical factor was characteristic only for the level of cadmium. Significant differences in the concentration of cadmium in the spleen in animals raised in the Maslyanino region from those bred in the Krasnozersk and Novosibirsk regions were revealed. For copper, zinc and lead reference intervals were calculated - 0.60-2.92; 17.2-26.0; 0.019-0.218 mg / kg, respectively. They can serve as a rough guideline for Hereford cattle bred in the Krasnozersk, Novosibirsk, Maslyanino districts of the Novosibirsk region and the Tselinny district of the Altai region.

A total of 18 wild edible mushrooms of Cantharellus species were collected from northwestern Himalayan region of India. The basic composition (moisture, total carbohydrates, dietary fiber, crude fat, ash, nitrogen and protein) and amino acid contents (by high-performance liquid chromatography) of these wild edible mushrooms were determined. The macronutrient profile in general revealed that the wild mushrooms were rich sources of protein and carbohydrates, and had low amounts of fat. Total phenolics and antioxidant activity from water and methanolic extracts of these mushrooms were also determined. These wild mushrooms also had significant amount of phenol content and antioxidant capacity. Studies also provide the precise antioxidant status of 18 indigenous species of mushrooms, which can serve as a useful database for the selection of mushrooms for the function of preparation of mushroom-based nutraceutics.
