| 中文摘要: |
| 目的:测定姜黄药材中重金属的含量,为建立姜黄药材重金属限量标准提供参考依据。方法:采用电感耦合等离子体质谱法测定27批姜黄样品中Cu、As、Cd、Pb的含量。结果:不同产地姜黄药材中重金属的含量存在较大差异,姜黄样品中Cu、As、Cd、Pb元素的含量分别为:2.62~9.34 μg/g,0.03~0.60 μg/g,0.01~5.39 μg/g,0.106~2.04 μg/g。4种重金属中仅镉元素超标,超标率为40.7%。结论:姜黄中重金属镉超标情况严重,部分姜黄药材镉元素污染达到中度污染或重度污染。建议建立姜黄重金属限量标准,为姜黄的规范种植与安全评价提供依据。 |
| English Summary: |
| To determinate the content of heavy metals in Rhizoma Curcumae Longae，and to provide reference for the establishment of heavy metal limit standards for Rhizoma Curcumae Longae medicinal materials.Methods:The contents of Cu，As，Cd，and Pb in 27 batches of Rhizoma Curcumae Longae samples were determined by inductively coupled plasma mass spectrometry (ICP-MS).Results:There were significant differences in the content of heavy metals in Rhizoma Curcumae Longae medicinal materials from different producing areas，the contents of Cu，As，Cd and Pb in Rhizoma Curcumae Longae samples were 2.62~9.34 μg/g，0.03~0.60 μg/g，0.01~5.39 μg/g，0.106~2.04 μg/g.Among the 4 heavy metals，only Cd exceeded the standard，and the rate of over-standard was 40.7%.Conclusion:The Cd in Rhizoma Curcumae Longae is seriously polluted，and some Cd pollution of Rhizoma Curcumae Longae has reached moderate or severe pollution.It is recommended to establish a limited standard for heavy metals in Rhizoma Curcumae Longae，and to provide a basis for the standard planting and safety evaluation of Rhizoma Curcumae Longae. |
