摘要
目的建立中药材中二氧化硫残留量快检方法。方法考查3种样品浸提方法对二氧化硫含量的影响,采用检测试剂盒法测定。结果碱性超声波浸提30min,样品中的二氧化硫达到峰值,该快检方法 RSD 1.0%(255.9mg/kg,n=6),样品加标回收率90.8%~97.4%,样品测定结果与药典方法结果一致。结论该快速检测方法具有简便、快速、灵敏、准确、经济等特点,适合在中药饮片生产经营企业、监管部门应用。
Objective To establish a quick detection method of sulfur dioxide residue in chinese medicinal materials.Methods The effect of 3 kinds of sample extraction methods on the content of sulfur dioxide was determined by the test kit method. Results The maximum sulfur dioxide was extracted from the sample with aqueous alk after 30 min sonication. The relative standard deviation( RSD) was 1. 0%( 255. 9mg / kg,n = 6). Recoveries of spiked samples varied from 90. 8% to97. 4%. The present method produced similar results compared to the chinese pharmacopoeia analysis. Conclusion The rapid detection method is simple,rapid,sensitive,accurate,and economical. It is applicable to the traditional chinese medicine enterprises and the regulatory authorities.
