【摘要】 建立了一种快速测定植物源中药材中SO₂残留量的氮吹辅助蒸馏-离子色谱法。采用该方法对市售342批植物源中药材中SO2残留量进行了检测和分析评价。检出的阳性样品有59批,检出率为17. 3%,检出SO2含量为3. 3～2271. 8 mg/kg。从样品类型来看,根茎类、花叶类样品的检出率（20. 0%、17. 4%）和平均含量（262. 1,337. 2 mg/kg）均较高。在检测的342批样品中,超过我国药典限量标准的有15批次,占总批次的4. 4%,说明中药材中存在一定程度的SO2残留,其潜在的的健康风险应当引起关注。更多还原

【Abstract】 A nitrogen-assisted distillation-ion chromatography method was developed to rapidly determine the residual amount of sulfur dioxide in Chinese herbal medicines. The sulphur dioxide residues in 342 Chinese herbal medicines( CHMs) were investigated by the above method and the potential risks were assessed.Among the 342 CHMs tested,59 samples were detected with the detection rate of 17. 3%,and the sulfur dioxide concentration ranged from 3. 3 mg/kg to 2271. 8 mg/kg. The detection rates( 20. 0%,17. 4%) and average levels( 262. 1,337. 2 mg/kg) of rhizomes and mosaics were higher than those of other sample types. 15 samples were detected with the concentration above the the maximum residue limit set by the Chinese Pharmacopoeia,which accounting for 4. 4% of the total samples. The results indicated potential health risks of sulfur dioxide in Chinese herbal medicines.更多还原
