摘要
为了研究中药鸡血藤中微量元素与药效之间的关系,继续开发利用鸡血藤,本文通过微波消解、湿法消解以及干法灰化处理鸡血藤样品,以Be、Y、Sc、In、Re作为内标进行基体效应补偿,通过电感耦合等离子体质谱(ICP-MS)法首次测定了鸡血藤中28种元素的含量。该方法简便、快速、准确,各元素检出限为0.01～0.8μg/L,标准偏差为0.11%～2.57%,加标回收率为94.00%～110.00%,适用于中草药中元素的分析。实验结果表明:鸡血藤中含有丰富的微量元素,含量在2mg/kg以上的元素就达13种,其中以Ca、K、Mg等元素含量最高,这与鸡血藤的药用效果相符,也为继续开发鸡血藤的药效提供了科学理论依据。
In order to study the relationship between trace elements of Spatholobus suberectus dunn and efficacy,and continue to develop and utilize Spatholobus suberectus dunn,ICP-MS was applied to simultaneously determine 28 elements concealed spatholobus suberectus dunn for the first time. The sample was dissolved with microwave digesting,wet digesting and dry ashing. The matrix effect was corrected by the in-line addition of internal standard （Be, Y, Sc, In, Re）. The analysis method is simple, rapid, accurate and fiting to the determination of elements in Chinese herbs. The detection limits of these element were in the range of 0. 01-0.8μg/L. The relative standards （RSD） were in the range of 0. 11%-2.57% ,and the recoveries were in the range of 94.00%-110.00%. The results show that large amounts of elements are embodied in spatholobus suberectus dunn. There are 13 kinds of element content in 2 mg/kg above. The contents of Ca,K and Mg are in conformation with the medical effects of spatholobus suberectus dunn. It can provide scientific basis for further development of the effect of Spatholobus suberectus dunn.
