Abstract: The contents of 5 anions including F-, Cl-, NO2, NO3 and PO4 in edible mushrooms such as Tricholoma giganteum, Boletus tomentipes and Leccinum rugosiceps were determined by ultrasonic-assisted extraction (UAE)-ion chromatography (IC) method. The results showed that the contents of other anions in each mushroom were ranked in the order of NO3 > PO4 > F-> Cl-, except that no NO2 was detected. The contents of each anion in different mushroom samples were different. This investigation can provide a reference for the determination of anions in edible mushrooms and guidance for the safety supervision of other species.

Key words: edible mushroom, ion chromatography, anions, content
