[Objectives] To determine the content of 10 kinds of inorganic elements (Pb, Cu, As, Cd, Hg, Zn, Fe, Mn, Sr and Cr) in samples of Paris polyphylla Smith var. yunnanensis (Franch. ) Hand.-Mazz. (and polygerm varieties) produced in different areas. [Methods] The wet digestion and technique of inductively coupled plasma optical emission spectrometry (ICP-OES) were used. [Results] Under the experimental conditions, elements were not related to each other, and several kinds of elements could be measured at the same time. The content of Pb exceeding the standard only in sample S4 of P. polyphylla Smith var. yunnanensis (and polygerm varieties), Hg was not detected in all samples, and the rest heavy metals did not exceed the limit. [Conclusions] This study was expected to proviie a certain reference for the development and utilization of P. polyphylla Smith var. yunnanensis (and polygerm varieties). [ABSTRACT FROM AUTHOR] |
