基于HS-SPME-GC-MS对云南地区雷公藤有毒蜜的分析

Research on Tripterygium Wilfordii Honey in Yunnan Based on HS-SPME-GC-MS

由于有毒蜜对消费者安全造成了一定威胁,如何高效鉴别有毒蜜成为当下的主要问题.为了实现对云南地区雷公藤有毒蜜的快速鉴别,本研究收集了云南姚安和哀牢山的雷公藤蜂蜜样品及云南地区常见的7种单花蜜样品,采用HS-SPME-GC-MS的方法对所收集蜂蜜样品的成分进行分析.结果表明,在雷公藤有毒蜜中存在一种高毒物质——对甲酚,其含量为0.005~0.11 mg/kg,此外在其他7种常见蜂蜜中仅在枣花蜜中发现了该成分,且含量较低为0.0017mg/kg.

Because toxic honey poses a threat to consumer safety, how to effectively identify toxic honey has become the main problem. In order to quickly identify the toxic honey of tripterygium wilfordii in Yunnan, samples of tripterygium wilfordii from Yao’an and Ailao Mountain in Yunnan and samples of 7 common single nectar in Yunnan were collected and analyzed by HS-SPME-GC-MS method. The results show that there is a highly toxic substance in the toxic tripterygium wilfordii honey--p-Cresol, the content of 0.005 mg/kg to 0.11 mg/kg, and in the other 7 common honey only found in jujube honey, and the content is low to 0.0017 mg/kg.
