主要出口中药材二氧化硫残留检测与分析

Detection and Analysis of Sulfur Dioxide Residues in Main Export Chinese Herbal Medicines

[目的]明确国内主要出口中药材二氧化硫残留现状,为相关单位制订许可标准提供资料。[方法]采用国家标准GB/T5009.34-2003的蒸馏法测定二氧化硫含量。[结果]此次检测中,测试样品均有不同程度的二氧化硫残留。采自亳州市场的白芍二氧化硫含量为632.69 mg/kg,远远超过残留限量;产自福建和浙江的石菖蒲中二氧化硫的含量均大于100 mg/kg的限量,其他中药材也普遍存在超标现象。[结论]我国中药材硫熏蒸现象普遍,较多中药材品种二氧化硫残留量严重超标,相关部门应加强对出口药材中熏制硫黄的控制工作。

[ Objective] To clarify the status of sulfur dioxide residues in main export Chinese herbal medicines in China and provide data for relevant units to develop license standards. [ Method] The content of sulphur dioxide was determined by distillation of the national standard GB/TS009.34 - 2003. [ Result ] The detection results showed that all test samples had different degrees of sulfur dioxide residues. Sulfur dioxide content in Radix Paeoniae Alba from Bozhou market was 632.69 mg/kg, far exceeding the residual limits; sulfur dioxide content in Rhizoma Acori Tatarinowii from Fujian and Zhejiang Province was above limit of 100 mg/kg, the excessive phenomenon was widespread in other Chinese herbal medicines. [ Conclusion] Sulfur dioxide fumigation of Chinese herbal medicine is still very common, sulfur dioxide residues are excessive seriously in many Chinese herbal medicines, the relevant departments should strengthen the control of Chinese herbal medicine smoked sulfur.
