Chemical Composition and Antioxidant Properties of Cultivated Button Mushrooms (Agaricus bisporus)
Hojat Ghahremani-majd,Farshad Dashti 한국원예학회 2015 Horticulture, Environment, and Biotechnology Vol.56 No.3
Mushrooms contain a variety of secondary metabolites, including various phenolic compounds and ergothioneine, which have been shown to act as excellent antioxidants. The present study reports a comparison of the antioxidant properties, total phenolic, ergothioneine and mineral contents of the most-consumed strains of Agaricus bisporus (white or brown colors). The samples were fruiting body, mycelia produced at farm (old mycelium) and in vitro (young mycelium). The antioxidant activity was measured by DPPH, FRAP and ABTS assays. The analysis of phenolic compounds was performed by Folin-Ciocalteau method. The mushroom strain with the highest ergothioneine, phenolic compounds and antioxidant potential was the strain A-SPA15 (brown color). Generally, fruiting body samples revealed higher ergothioneine, phenolic compounds and antioxidant properties than mycelia obtained from farm and in vitro culture. There were variations in the mineral content of A. bisporus harvested from the fruiting body, old mycelium, and young mycelium. Furthermore, the lowest heavy-metal concentrations (Ni, Pb, Cd, and Cr) were detected in mycelium samples in each strain. Results demonstrated that mushrooms contained high amounts of copper, zinc, iron and manganese could be used in well-balanced diets. This study contributes to the data relative to A. bisporus consumed as fresh mushrooms and the possibility of in vitro production as a source of bioactive compounds.

Antioxidant and Antimicrobial Activities of Iranian Mooseer (Allium hirtifolium Boiss) Populations
Hojat Ghahremani-majd,Farshad Dashti,Dara Dastan,Hasan Mumivand,Javad Hadian,Mahmood Esna-Ashari 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.2
Mooseer or Persian shallot is a bulbous perennial herb belonging to the Alliaceae family. Antioxidant activities of 12 mooseer populations were determined using three assays including DPPH, FRAP, and ABTS. Antioxidant activities differed among all populations with the Sahneh and Nahavand population as the highest and the lowest, respectively. Antimicrobial activity of mooseer extracts were tested against six bacteria including Staphylococcus aureus, Enterococcus faecalis, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae and two fungi including Candida albicans and Saccharomyces cerevisiae by disc diffusion method by determining their minimum inhibitory concentration values with all samples indicating moderate to high antimicrobial activity. For antimicrobial activity, Esfahan population showed the highest inhibitory effect on bacteria and fungi. According to the results of the study, mooseer has potential as a valuable dietary supplement.
