Resumo(s)
Analysis of phenolic compounds in sixteen Portuguese wild mushrooms species has been carried out by
high-performance liquid chromatography coupled to photodiode array detector and mass spectrometer
(HPLC–DAD–ESI/MS). No flavonoids were detected in the analysed samples, but diverse phenolic acids
namely protocatechuic, p-hydroxybenzoic and p-coumaric acids, and two vanillic acid isomers were
found and quantified. A related non-phenolic compound, cinnamic acid, was also detected in some samples,
being the only compound found in Cantharellus cibarius (14.97 mg/kg, dry matter), Lycoperdon perlatum
(14.36 mg/kg) and Macrolepiota procera (21.53 mg/kg). p-Hydroxybenzoic acid was found in the
majority of the samples, being the most abundant compound in Agaricus silvicola (238.7 mg/kg). Ramaria
botrytis showed the highest phenolic acids concentration (356.7 mg/kg) due to the significant contribution
of protocatechuic acid (342.7 mg/kg).
