摘要: 为检测不同地区中药材黄精(Polygonati Rhizoma)中的二氧化硫含量并对其安全性进行评价,采用凯氏定氮仪对黄精药材样品蒸馏,依据国家标准进行碘标准溶液滴定。结果显示,有8种样品存在二氧化硫残留,其中超过国家限量标准(150 mg/kg)的有4种,样品检出率为7.5%,按照GB 2760—2014食品添加剂使用标准(50 mg/kg)检出超标样品7种,检出率为13.2%。

Abstract: In order to detect the sulfur dioxide content in Polygonati Rhizoma from different regions and evaluate its safety, the samples of Polygonati Rhizoma were distilled by Kjeldahl nitrogen analyzer, and iodine standard solution titration was carried out according to national standards. The results showed that 8 kinds of samples had sulfur dioxide residue, of which 4 exceeded the national limit standard (150 mg/kg), and the detection rate was 7.5%. According to the GB 2760—2014 food additive use standard (50 mg/kg), 7 kinds of samples exceeded the standard, and the detection rate was 13.2%.

Key words: Chinese herbal medicine, Polygonati Rhizoma, sulfur dioxide, Kjeldahl method for determination of nitrogen, safety evaluation
