人参须药材中重金属残留量的测定

Determination of Heavy Metal Residues in Ginseng Leptoradix

目的:对11批人参须药材重金属残留量进行测定。方法:依据2015年版《中华人民共和国药典》通则2321:铅、镉、砷、汞、铜测定法项下,对铅、镉、砷、汞、铜的残留量进行了测定。结果:通过对铅、镉、砷、汞、铜5种重金属元素检测及方法学考察,结果合理有效,标准曲线的线性相关系数均大于0.995,平均加样回收率分别为107%、81%、88%、80%和78%。11批样品的重金属残留量均在限度范围内。结论:本研究中所用的人参须药材重金属及有害元素污染程度较低,安全性相对较好。

Objective： To determine the residue of heavy metals in Ginseng Leptoradix. Methods： According to Chinese Pharmacopoeia（ CP） 2015. Determination the residue of Pb,Cd,As,Hg,Cu. Results： The results were reasonable and effective through the detection and methodological study of Pb,Cd,As,Hg and Cu. The linear correlation coefficients were greater than 0. 995. The average recoveries were 107% 、81% 、88% 、80% 、78%. The heavy metal residues of 11 batches of samples are within limits. Conclusion： The sample in this reach is lower level of heavy metal pollution and harmful elements,security is relatively well.
