恩施州GAP地道药材品种安全性评价

目的：评价恩施州GAP地道药材品种的安全性。方法：通过对恩施州的12个GAP药材品种药用部位、种植土壤的重金属元素的分析研究，查明了药材中重金属铅、砷、镉、铬、汞的含量及分布特征。结果：铬是药材中主要污染元素，在被检测的药材中超标的占25％；其次为镉、铅分别有一个品种超标，占被检测对象的8．3％；其它无超标现象。结论：恩施州的12个GAP地道药材品种的安全性较好，基本符合国家有关药用植物出口标准；个别元素超标的问题还需进一步研究。

Security Estimate in Indigenous GAP Chinese Medicinal Breeds of Enshi Canton

Objective:To estimate the security of GAP Chinese medicinal breeds of Enshi Prefecture. Methods: Analyses on heavy metals in officinal part and plant soils of 12 species GAP breeds in Enshi Prefecture were conducted to study the content and distribution of heavy metals as Pb,As,Cd,Cr and Hg in Chinese medicinal herbs. Results:Cr is the main polluting elements in the Chinese medicinal herbs with 25% exceeding the permissible limits of relevant standard, in the next place with 8. 3% exceeding standard of Cd,Pb,has one GAP breed exceed standard. The other elements are in safe range of those Chinese herbs. Conclusion:The security of 12 indigenous GAP Chinese medicinal breeds of Enshi Prefecture is very high and they can meet the standards of Chinese exported relevant medical plants; while the problem that some special elements surpass the norms should be further discussed.
