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 provide a certain reference for the development and utilization of P. polyphylla Smith var. yunnanensis( and polygerm varieties).展开更多

Hand.-Mazz.( polygerm varieties) produced in Gaoligong Mountain areas,and provide experimental data for their identification and application. [Methods] The original plant powder was used,and paraffin sections and physicochemical properties were identified. [Results]P. polyphylla Smith var. yunnanensis( polygerm varieties) produced in Gaoligong Mountain areas showed obvious microscopic features and physicochemical properties. [Conclusions] This study was expected to provide certain reference for identification of original plant and medicine and formulation of quality standard for P. polyphylla Smith var. yunnanensis( polygerm varieties) produced in Gaoligong Mountain areas,and provided basis for their further research and development.展开更多
