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 investigate the feasibility of rapid determination of sulfur dioxide residues in Chinese herbal medicines by using sulfur dioxide detector. Methods: The residues of sulfur dioxide in seven batches of sulfur-fumigated Chinese medicinal materials such as Codonopsis pilosula, Ophiopogon japonicus, Polygonatum odoratum, Chinese yam, and Chinese zebrafish, respectively, were determined by lead acetate distillation and rapid determination of sulfur dioxide. Results: There was no significant difference in the results of sulfur dioxide residues in seven batches of Chinese medicinal materials measured by lead acetate distillation and sulfur dioxide rapid test (P> 0.05), which shows that the two methods are equivalent. Conclusion: The detection method of sulfur dioxide rapid detector can be used as a rapid detection of residual sulfur dioxide in traditional Chinese medicine for the quality control of Chinese herbal medicines.
