摘　　要：为深入了解黑木耳的营养价值,为消费者的选择提供理论依据,采用电感耦合等离子体原子发射光谱(ICP-AES)法测定黑龙江(东北)与云南省临沧市、丘北县和凤庆县4个产地黑木耳中18种矿质元素的含量。结果表明:供试样品中含有丰富的钙、镁、钾、磷、铁、铜、锌、硅等人体必需矿质元素;不同产地的黑木耳中同一种矿质元素的含量不同,黑龙江黑木耳的人体所需的矿质元素Ca、Co、Fe、P、Zn、Cr含量较高,分别达9838.82μg/g、0.44μg/g、701.48μg/g、1 963.22μg/g、32.6μg/g和1.74μg/g;凤庆黑木耳的人体所需的矿质元素Cu、K和Se含量较高,分别为14.79μg/g、9 700.51μg/g和8.35μg/g;丘北黑木耳矿质元素含量较低,Ca、Mg、P、Fe、Cu和Zn含量仅有2 317.61μg/g、2 255.31μg/g、1 082.45μg/g、423.47μg/g、3.75μg/g和17.95μg/g。黑龙江和云南凤庆黑木耳矿质元素含量丰富,具有较高的营养价值和保健作用。To deeply explore the nutritive value of A.auricular,and provide a theoretical reference for consumers to select,inductively coupled plasma-atomic emission spectrometry（ICP-AES）was employed to determine 18 mineral elements in A.auricular from different producing areas,including Heilongjiang（northeast）,Lincang City,Qiubei County and Fengqing County of Yunnan.Results：Abundant calcium,magnesium,potassium,phosphorus,iron,copper,zinc,silicon and other essential mineral elements were detected in the samples;The same mineral element in A.auricular from different regions had different contents;There were higher contents of mineral elements such as Ca,Co,Fe,P,Zn and Cr in A.auricularfrom the northeast regions,the contents of mineral elements were respectively 9 838.82μg/g,0.44μg/g,701.48μg/g,1 963.22μg/g,32.6μg/g and 1.74μg/g.There were higher contents of mineral elements with Cu,K and Se from Fengqing County,the contents were respectively 14.79μg/g,9700.51μg/g and 8.35μg/g.There were lower contents with Ca,Mg,P,Fe,Cu and Zn from Qiubei County,the contents were respectively 2 317.61μg/g,2 255.31μg/g,1 082.45μg/g,423.47μg/g,3.75μg/g and 17.95μg/g.A.auricularfrom northeast and Fengqing country of Yunnan regions were of higher nutritional values and health care function.
