Total phenols, ascorbic acid, β-carotene and lycopene in Portuguese wild edible mushrooms and their antioxidant activities
Abstract The antioxidant activities of three Portuguese wild edible mushroom species, Leucopaxillus giganteus, Sarcodon imbricatus, and Agaricus arvensis , were evaluated. Methanolic extracts wereExpand
A review on antioxidants, prooxidants and related controversy: natural and synthetic compounds, screening and analysis methodologies and future perspectives.
The present review tries to shed some light on research on antioxidants (natural and synthetic) and prooxidants, showing the potential benefits and adverse effects of these opposing events, as well as their mechanisms of action and detection methodologies. Expand
Free-radical scavenging capacity and reducing power of wild edible mushrooms from northeast Portugal : individual cap and stipe activity
Abstract The antioxidant properties of two wild edible mushroom species from the northeast of Portugal, Lactarius deliciosus (L.) Gray and Tricholoma portentosum (Fr.) Quel., were evaluated.Expand
Wild and commercial mushrooms as source of nutrients and nutraceuticals.
Wild mushrooms revealed a higher content of phenols but a lower content of ascorbic acid, than commercial mushrooms, and there were no differences between the antimicrobial properties of wild and commercial species. Expand
Antioxidant activity of Portuguese honey samples: Different contributions of the entire honey and phenolic extract
The antioxidant activity of Portuguese honeys was evaluated considering the different contribution of entire samples and phenolic extracts. Several chemical and biochemical assays were used to screenExpand
Antioxidants in wild mushrooms.
The antioxidant properties of wild mushrooms have been extensively studied, and many antioxidant compounds extracted from these sources have been identified, such as phenolic compounds, tocopherols, ascorbic acid, and carotenoids. Expand
Strawberry-tree, blackthorn and rose fruits: detailed characterisation in nutrients and phytochemicals with antioxidant properties.
The combination of bioactive compounds and rich nutritional composition of the studied wild fruits make them a very special food. Expand
Chemical composition and biological properties of portuguese wild mushrooms: a comprehensive study.
Lycoperdon species were resistant to all of the tested microorganisms, and the other samples revealed antimicrobial activity selectively against Gram-positive bacteria, with very low minimal inhibitory concentration, in some cases, even lower than the standard. Expand
Bioactive properties and chemical composition of six walnut (Juglans regia L.) cultivars.
All the walnut extracts exhibited antioxidant capacity in a concentration-dependent manner being the lowest EC(50) values obtained with extracts of cv. Expand
Fatty acid and sugar compositions, and nutritional value of five wild edible mushrooms from Northeast Portugal
The chemical composition and nutritional value of five wild edible mushroom species (Agaricus arvensis, Lactarius deliciosus, Leucopaxillus giganteus, Sarcodon imbricatus, Tricholoma portentosum)Expand
