地理标志产品抚顺哈什蚂多元特征元素的分析研究

Analysis of the characteristic elements of product of geographical indication Fushun forest frog’s oviduct

采用VISTA—MPX等离子体发射光谱仪对地理标志产品抚顺哈什蚂油及其他地域生产的蛙油中十种元素的含量进行了测定。通过比对和分析研究，地理标志保护产品抚顺哈什蚂油中硼、铁、钾含量较高，其中硼平均含量1．59μg／g，是其他地区蛙油硼含量的1．25-2．06倍，铁平均含量51．92μg／g，是其他地区蛙油铁含量的1．48～2．9倍，钾含量平均为1．48％，是其他地区蛙油钾含量的1．0～2．9倍。而铜和镁含量总体偏低，铜平均含量为7．02μg,／g，镁为0．058％。抚顺林蛙油中Fe／Cu与Fe／Zn比值较高，分别约为7．39和3．27，且十种元素含量可构成特征曲线，为抚顺林蛙油的真伪鉴别以及质量追溯提供参考依据。

10 kinds of element＇ s content of product of geographical indication Fushun forest frog＇ s oviduct and productions from other regions were determined using the VlSTA-MPX inductively coupled plasma atomic emission spectrometer.It was concluded by means of comparison and analysis that the contents of boron,iron and potassium were higher in Fushun forest frog＇ s oviduct.The average content of boron was 1.59μg/g,which was 1.25-2.06 times of that of content in other local product.The average content of iron was 51.92μg/g,which was 1.48-2.9 times of iron content of other local frog oil.The potassium content was 1.48% equally, which was 1.0-2.9 times of others. But the overall contents of copper and magnesium were somewhat lower.the average content of copper was 7.02μg/g and that of magnesium was 0.058%.Besides, the ratios of Fe/Cu and the Fe/Zn in Fushun forest frog＇ s oviduct were higher,which were about 7.39 and 3.27 respectively. The contents of 10 kinds of elements may constitute a characteristic curve so as to supply reference for identifying and quality tracing Fushun forest frog＇ s oviduct.
