| 摘要: |
| 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分析测试3年生、4年生和5年生的广西靖西县的三七中微量元素及重金属的含量,为广西建立三七规范化生产基地提供实验依据。结果表明:广西靖西县的三七中含有丰富的Zn、Fe、Cu、Mn和Ni等微量元素,微量元素随药龄的变化而变化,但变化无规律性;广西三七中重金属含量较低,除5年生三七中Hg含量偏高外,其他均符合国家标准。 |

| Abstract: |
| To supply experimental data for the establishment of a standardized production base of Radix notoginseng in Guangxi, the contents of trace elements and heavy metals in Radix notoginseng in different growth periods were determined by atomic fluorescence spectrophotometry, atomic absorption spectrophotometry and inductive coupling plasma radiation spectophotometry respectively.The results showed that the contents of trace elements varied with different growth periods, but no regularity;the contents of heavy metals were very low and were in accordance with demands of the national standard in the plants of the five growth period except mercury. |
