[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 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
以华重楼[Paris polyphylla Smith var.chinensis(Franch.)Hara]植物多种器官为外植体,经不同消毒处理和培养基诱导培养后,观察其愈伤组织的诱导生长情况;并以TTC法检测诱导产生的愈伤组织中的薯蓣皂苷含量。结果表明,华重楼的隐芽、内...以华重楼[Paris polyphylla Smith var.chinensis(Franch.)Hara]植物多种器官为外植体,经不同消毒处理和培养基诱导培养后,观察其愈伤组织的诱导生长情况;并以TTC法检测诱导产生的愈伤组织中的薯蓣皂苷含量。结果表明,华重楼的隐芽、内层芽鞘、根茎、预处理后根茎和子房外植体经诱导培养后,均可不同程度地产生愈伤组织;其中以预处理后根茎外植体产生的愈伤组织生长速度最快,诱导率也最高,为33.5%。经检测结果显示,多次继代培养的华重楼愈伤组织中含有与华重楼对照药材和薯蓣皂苷对照品相同的薯蓣皂苷或其类似物。展开更多
