title: Antioxidant capacity and mineral contents of edible wild Australian mushrooms.
abstract: Five selected edible wild Australian mushrooms, Morchella elata, Suillus luteus, Pleurotus eryngii, Cyttaria gunnii, and Flammulina velutipes, were evaluated for their antioxidant capacity and mineral contents. The antioxidant capacities of the methanolic extracts of the dried caps of the mushrooms were determined using a number of different chemical reactions in evaluating multi-mechanistic antioxidant activities. These included the Trolox equivalent antioxidant capacity, ferric ion reducing antioxidant power, and ferrous ion chelating activity. Mineral contents of the dried caps of the mushrooms were also determined by inductively coupled plasma-optical emission spectroscopy. The results indicated that these edible wild mushrooms have a high antioxidant capacity and all, except C. gunnii, have a high level of several essential micro-nutrients such as copper, magnesium, and zinc. It can be concluded that these edible wild mushrooms are good sources of nutritional antioxidants and a number of mineral elements.
