| 摘 要： | 采用聚焦微波样品处理系统对中草药龙胆草进行水浸取处理,通过C18反相色谱柱对浸取液进行分离,此后采用流动注射－ICP－MS对其中的9种元素的游离态及结合态进行了测定,并研究了浸取条件对浸出率的影响。利用正交设计对微波浸取的条件（时间、温度、料液比）进行了优化。

| Abstract: | A method based on focused microwave extraction for leaching 9 trace elements in traditional Chinese medicine Long Dan Cao was introduced.An online C 18 enrichment-separation system and an HP4500 ICP mass spectrometer with a flow injection system was established for the separation and determination of inorganic speciation and organic speciation of the selected elements.Orthogonal design was applied for the optimization of microwave leaching conditions.The results showed that the temperature was the major factor for the leaching recoveries. |
