Do bioactive carotenoids contribute to the color of edible mushrooms?

Ribeiro, Bárbara; Pinho, Paula Guedes de; Andrade, Paula B.; Oliveira, Carla; Ferreira, António César Silva; Baptista, Paula; Valentão, Patrícia

Carotenoids are biologically active phytochemicals present as micro-components in fruits and vegetables, being responsible for their yellow, orange and red colors. The chromatographic behavior and the UV absorption spectrum provided by HPLC-DAD analysis constitute the clues for their identification. Mushrooms are of increasing importance in modern nutrition and medicine, due to the presence of metabolites with ...

Metabolite profiling of wild edible mushrooms species

Valentão, P.; Ribeiro, Bárbara; Pinho, P. Guedes de; Baptista, Paula; Andrade, P.B.

Mushrooms are of increasing importance in modern nutrition and medicine. Trás-os-Montes region (north-eastern Portugal) is known for the variety of its soils and diversity of climate conditions. This variability assumes an important role in mushroom production, explaining why this region is recognized as one of the richest ones in wild edible species. A metabolomics approach was applied to twelve wild edible mu...

Fatty acid composition of wild edible mushrooms species: a comparative study

Ribeiro, Bárbara; Pinho, P. Guedes de; Andrade, P.B.; Baptista, Paula; Valentão, P.

A comparative study was developed on the total fatty acids composition of twelve wild edible mushroom species (Suillus bellini, Suillus luteus, Suillus granulatus, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica, Cantharellus cibarius, Amanita caesarea and Hydnum rufescens). In order to define qualitative and quantitative profiles, combined...

Ribeiro, Bárbara; Lopes, Rosário; Andrade, P.B.; Seabra, R.M.; Gonçalves, Rui; Baptista, Paula; Quelhas, Inês; Valentão, P.

A comparative study of the organic acids and phenolics composition and of the total alkaloids content of entire wild edible mushrooms (Russula cyanoxantha, Amanita rubescens, Suillus granulatus and Boletus edulis) and correspondent caps and stipes was performed. All species presented oxalic, citric, malic and fumaric acids, with A. rubescens exhibiting the highest total organic acids content. Organic acids were...
