采用蒸馏碘滴定法测定了经硫磺熏制后党参中二氧化硫的残留量。结果表明，含水量对党参中二氧化硫残留量影响不显著，而硫磺用量、熏制时间对党参中二氧化硫残留量影响极显著，当党参含水量为25%～31%、硫磺用量为0.025 kg/kg党参、熏制24 h时党参中二氧化硫残留量相对较小。熏制党参时，应在不影响药效的前提下适量减少硫磺用量，缩短熏制时间。

Using the distilling of iodine titration method to study the sulfur dioxide residues in Codonopsis pilosula after smoked. The results showed that the amount of sulfur and the moisture gradient have biggest influence; the time of sulfur smoked has less effect . When the moisture gradient distributed in 25%~31%, the sulfur amount controled in 0.025 kg/kg, smoked 24h, the sulfur dioxide residues reached lower level . When we smoked to Codonopsis pilosula, we’d better reduce the sulfur amount and smoked time, pharmacodynamic action is very important .
