摘　　要：目的:分析不同产地不同商品规格西洋参中二氧化硫的残留情况。方法:采用《中国药典》2010年版一部规定的酸蒸馏碘滴定方法检测西洋参中二氧化硫残留量。结果:西洋参样品二氧化硫的含量均低于5mg.kg-1,远远低于国际规定的限量标准;西洋参产地和商品规格与二氧化残留硫量相关关系不明显。结论:国家有关部门在制定西洋参二氧化硫残留量限量标准时应将西洋参作为传统不硫熏的药材对待。Objective： To analyze the content of residual sulphur dioxide in american ginseng of different regions and commercial grades. Methods：The residual sulphur dioxide were determined by the iodine titration method from Chinese Pharmacopoeia of 2010 edition. Results：The residual sulphur dioxide in american ginseng of different regions and commercial grades were far lower than the international limit. There is no correlation between commercial grades and residual sulphur dioxide. Conclusion： State department should strictly build the limited quantity＇ s statutory standards of the residual sulphur dioxide of american ginseng as traditional medicinal materials without stove drying.
