微波消解-ICP-MS法测定青海和西藏产区冬虫夏草中的35种元素
Determination of 35 elements in Chinese caterpillar fungus from Qinghai and Tibet by microwave digestion-lCP-MS
摘要
Abstract
To determine the contents of 35 elements(including 16 rare earth elements)in 17 batches of Chinese caterpillar fungus from Qinghai and Tibet and make preliminary identification analysis of their habitats,a total of 35 elements in Chinese caterpillar fungus samples were determined by microwave digestion-ICP-MS,including 3 batches from Yushu,4 batches from Naqu and 10 batches from Guoluo.Furthermore,cluster analysis was carried out on the measurement results of 3 producing areas. Results showed that the contents of 35 elements in 17 kinds of Chinese caterpillar fungus samples from different origins have obvious differences. And the limits of the 4 kinds of harmful elements(Cd,Pb,As and Cu) were recommended. The results of cluster analysis showed that the samples from Yushu and Guoluo were close,and the difference was small,while the sample from Naqu was far away,and its relative difference was larger. This method is quick,accurate and feasible,which provides a theoretical basis for quality control and medication guidance of Chinese caterpillar fungus from different habitats.关键词
