二氧化硫速测仪测定中药材中二氧化硫残留量实验研究

Determination of Sulfur Dioxide Residues in Traditional Chinese Medicine by Sulfur Dioxide Tachometer

目的:考察采用二氧化硫速测仪快速测定中药材中二氧化硫残留量的可行性。方法:分别采用醋酸铅蒸馏法和二氧化硫速测法测定党参、麦冬、玉竹、山药、浙贝等7批经过硫磺熏蒸的中药材中二氧化硫残留量。结果:醋酸铅蒸馏法和二氧化硫速测法所测定的7批中药材中二氧化硫残留量结果比较差异无统计学意义(P>0.05),说明两种方法效果相当。结论:二氧化硫速测仪检测法可作为中药材中二氧化硫残留量的快速检测方法,用于中药材的质量控制。

Objective：To study the feasibility of sulfur dioxide residues in traditional Chinese medicine detected by Sulfur dioxide Tachometer.Methods：Seven batches sulfur fumigation traditional Chinese medicine,Codonopsis pilosula,Ophiopogon japonicas,Polygonatum odoratum,Chinese yam,Fritillaria thunbergii,were detected their sulfur dioxide residues by lead acetate distillation and Sulfur dioxide Tachometer.Results：The results of two methods were established a database with the statistics software 19.0 and tested by paired T.The result means that there was no significant difference between two methods（P〉0.05）.Conclusion：the method of Sulfur dioxide Tachometer can be used rapid screening of sulfur dioxide in traditional Chinese medicine.
