| 摘要: |
| [目的]测定不同产地田七(Panax notoginseng)主根及田七不同部位的重金属和微量元素含量,为广西建立田七规范化生产基地提供实验依据。[方法]采用原子荧光光谱法、原子吸收分光光谱法及电感耦合等离子体发射光谱法进行测定分析。[结果]除镉(Cd)含量偏高外,其它重金属含量均符合绿色行业标准。另Cd含量在根茎中最高,其他测定的铅(Pb)、铜(Cu)、汞(Hg)和砷(As)等重金属及微量元素都以须根中含量最高,主根中最低。[结论]不同产地的田七主根重金属元素含量存在差异,但没有明显变化规律;田七不同部位富集重金属及微量元素的能力有差异。 |

| Abstract: |
| [Objective] In this study,several trace elements and heavy metals from different parts of Panax notoginseng radix producing in different areas were detected.[Methods] The experimental data obtained from atomic fluorescence spectrophotometry,atomic absorption spectrophotometry and inductive coupling plasma radiation spectophotometry provide the reference for the establishment of the standardized Panax notoginseng production base in Guangxi.[Results] The results showed that the concentration of heavy metals,except Cd,were low,which met the national green standard. The Cd concentration is highest in the rhizome,but the concentration of other heavy metals such as Pb,Cu,Hg and As are highest in the fiber.[Conclusion] The heavy metals concentration of Panax notoginseng radix from different areas were different without obvious pattern,which might due to the different heavy metals absorption ability of Panax notoginseng radix. |
