摘要: 采用超声波辅助提取-离子色谱法测定大白口蘑、绒柄牛肝菌和皱盖疣柄牛肝菌3种食用菌中F-、Cl-、NO2、NO3、PO4五种阴离子含量。结果表明:3种样品中,离子含量均表现为NO3>PO4>F->Cl-,且NO2均未检测出;同一种离子在不同样品中的含量各有差异。本研究为食用菌中阴离子含量的监测提供参考,同时对其他物种的安全监督具有指导意义。

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.
