摘 要：[Objectives] To determine 29 kinds of inorganic elements in samples of Paris daliensis *** et *** and P. dulongensis *** et *** produced in different regions, and to measure the content of 10 key inorganic elements: chromium(Cr), manganese(Mn), iron(Fe), copper(Cu), mercury(Hg), zinc(Zn), arsenic(As), antimony(Sr), cadmium(Cd) and lead(Pb). [Methods] The wet digestion and technique of inductively coupled plasma optical emission spectrometry(ICP-OES) were employed. [Results] Under the experimental conditions, elements were not related to each other, and many kinds of elements could be measured at the same time; toxic and heavy metals in samples of P. daliensis *** et *** and P. dulongensis *** et *** did not exceed the limit; Hg was not detected in all samples. [Conclusions] This method is simple, easy to operate and reproducible. It can be used for the detection of inorganic elements in P. daliensis *** et *** and P. dulongensis *** et ***; the heavy metals and Hg of the rhizome meet the requirements of the limit of medicinal materials.
