Antioxidant activities, metal contents, total phenolics and flavonoids of seven Morchella species
No full textSeven Morchella species were analyzed for their antioxidant activities in different test systems namely beta-carotene/linoleic acid, DPPH, reducing power, chelating effect and scavenging effect (%) on the stable ABTS(center dot+), in addition to their heavy metals, total phenolic and flavonoid contents. In beta-carotene/linoleic acid system, the most active mushrooms were M. esculenta var. umbrina and M. angusticeps. In the case of DPPH, methanol extract of M. conica showed high antioxidant activity. The reducing power of the methanol extracts of mushrooms increased with concentration. Chelating capacity of the extracts was also increased with the concentration. On the other hand. in 40 mu g ml(-1) concentration, methanol extract of M. conica, exhibited the highest radical scavenging activity (78.66 +/- 2.07%) when reacted with the ABTS(center dot+) radical. Amounts of seven elements (Cu, Mn, Co, Zn, Fe, Ca, and Mg) and five heavy metals (Ni, Pb, Cd, Cr, and Al) were also determined in all species. M. conica was found to have the highest phenolic content among the samples. Flavonoid content of M. rotunda was also found superior (0.59 +/- 0.01 mu g QEs/mg extract). 2009 Elsevier Ltd.

Evaluation of antioxidant activities of 3 edible mushrooms: Ramaria flava (Schaef.: Fr.) Quél., Rhizopogon roseolus (Corda) T.M. Fries., and Russula delica Fr.
No full textThe methanolic extracts of Ramaria flava, Rhizopogon roseolus", and Russula delica were analyzed for their antioxidant, activities in different test systems including. beta-carotene/linoleic acid, 1.1-dipheny1-2-picrylhydrazyl (DPPH) free radical scavenging, reducing power, and metal chelating activities in addition to their total phenolic and flavonoid contents. In the first case, methanol extract of R. roseolus showed the strongest activity. In DPPH system, the scavenging effects increased with the concentration. The reducing power of the mushroom also increased with concentration. Chelating effect was 96.75 +/- 0.28% for R. flava In the case of total phenolic and flavonoid assays, R. flaw found to have the highest phenolic content. Total flavonoid content of R. flava again found the superior to the other mushrooms. Experimental results indicate that the mushroom species evaluated here can be consumed safely. On the other hand, knowing the biological activity of these mushrooms will contribute to the establishment of conscious consumption
Evaluation of metal concentration and antioxidant activity of three edible mushrooms from Mugla, Turkey
No full textThis study is designed for the determination of metal concentrations, antioxidant activity potentials and total phenolics of Amanita caesarea, Clitocybe geotropa and Leucoagaricus pudicus. Concentrations of four heavy metals (Pb, Cd, Cr, Ni) and five minor elements (Zn, Fe, Mn, Cu, Co) are determined. In the case of A caesarea, Cr and Ni concentrations are found in a high level. Concentrations of the metals are found to be within safe limits for C. geotropa. In beta-carotene/linoleic acid test, L pudicus showed the highest activity potential. In DPPH system, A. caesarea showed 79.4% scavenging ability. Additionally, reducing power and chelating capacity of the mushrooms increased with concentration. The strongest super-oxide anion scavenger was A. caesarea. In the case of total phenolics, L pudicus found to have the highest content. (C) 2010 Elsevier Ltd. All rights reserved
Growth of mycelium of three ectomycorrhizal macrofungi, Infundibulicybe geotropa, Tricholoma anatolicum and Lactarius deliciosus in culture media containing various carbon sources
No full textA comparative evaluation was conducted to assess the effects of different carbon sources on the mycelial growth of three species of ectomycorrhizal macrofungi; Infundibulicybe geotropa (Bull.) Harmaja, Tricholoma anatolicum H. H. Dogan & Intini and Lactarius deliciosus (L.) Gray. All carbon sources were found to be equally beneficial for mycelial growth. However, sucrose, glucose and arabinose were found to be better carbon source in solid culture for L. deliciosus, T. anatolicum and I. geotropa as the maximum biomass values in the liquid medium at the end of 56 days incubation period and were measured as 66.0, 43.0 and 97.0 mg, respectively

Antimicrobial activity of two wild mushrooms Clitocybe alexandri (Gill.) Konr. and Rhizopogon roseolus (Corda) T.M. Fries collected from Turkey
No full textTwo edible wild mushrooms, namely Clitocybe alexandri (Gill.) Konr. (Tricholomataceae) and Rhizopogon roseolus (Corda) T.M. Fries (Rhizopogonaceae), collected from the southwest of Turkey, were tested for their antimicrobial activity by using the disc diffusion method. The ethanol, methanol, diethyl ether, water, ethylacetate and n-hexane extracts from the fruit bodies of mushrooms were assayed against 13 microorganisms. In comparison with the test antibiotics penicillin, novobiocin, nalidixic acid and ampicillin, the methanol extract obtained from the two mushrooms presented significant activity against E. coli, Bacillus subtilis and Enterobacter aerogenes. On the other hand, the ethylacetate extract from C. alexandri was found to be active against Candida albicans and Saccharomyces cerevisiae, whereas the ethanol extract of Rhizopogon roseolus was active against Saccharomyces cerevisiae. This research has shown that various extracts obtained from two macrofungi could be used in vitro to inhibit the growth of some important bacteria and fungi. Copyright © 2006 John Wiley & Sons, Ltd

Minerals, phenolics, and biological activity of wild edible mushroom, Morchella steppicola Zerova
No full textTasteful morels (Morchella sp.) are one of the most popular mushrooms, both economically and scientifically. Due to their beneficial constituents, they are classified as functional foods. This study focuses on the chemical composition and biological activities of a wild edible mushroom, Morchella steppicola Zerova. The metal composition of this species reveals high levels of biogenic elements. However, according to the levels of iron and cobalt, and calculated health risk indices, this mushroom can be recommended for occasional consumption. Also, M. steppicola is found to be rich in gallic acid, protocatechuic acid, 4-hydroxybenzoic acid, and vanillic acid. Statistical analysis showed that mainly 4-hydroxybenzoic and vanillic acids are responsible for both antioxidant and inhibition of enzymes alpha-amylase and tyrosinase. Presented work acknowledges the fact that this mushroom has significant potential to be used for the treatment of several human disorders, similarly to other members of this genus
