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 cap and stipe was performed. All species presented oxalic, citric, malic and
fumaric acids. Phenolic compounds were present in all of the analyzed species, beingp-hydroxybenzoic acid
identified in A. rubescens and S. granulatus species. It seems that this compound may have a propensity to
accumulate in the cap of A. rubescens. B. edulis was the species that presented the highest total alkaloids
amounts. All species revealed DPPH radical scavenging activity, being B. edulis the most effective one
