桂枝茯苓胶囊及药材中多元素ICP—MS测定方法的建立(3)
[Abstract] This paper was focused on establishing a ICP-MS method with microwave digestion for simultaneous determination of lead， copper， arsenic， cadmium， mercury， magnesium， manganese， nickel， thallium in cassia tuckahoe capsule and its five raw herbal materials. Internal standard method was adopted to reduce matrix effect and other interference effects. The method established was shown to be simple with high sensitivity， strong specificity and good reproducibility. linear relationship is good as R2≥0.999 3 while the average recovery was among 75.84%-118.9%.The detection limit was 0.016-4.593 μg·L-1. Data in this paper provided the basis for control of deleterious element in Guizhi Fuling capsules， and further more it was with referencing values for control of deleterious element in other crude drug.
