| 目的：以不同种质资源的九牛草绒和艾叶绒为研究对象，比较九牛草和艾叶2种艾资源的叶绒燃烧后烟尘中的挥发性成分及室内空气污染物浓度，为九牛草的进一步开发利用提供科学支撑。方法：采用顶空固相微萃取-气相色谱-质谱法（HS-SPME-GC-MS）检测叶绒燃烧烟尘中的挥发性成分，并对所有挥发性成分进行聚类分析；使用空气质量检测仪对叶绒燃烧后空气中甲醛、总挥发性有机化合物（TVOC）、PM2.5和PM10的浓度进行检测。结果：九牛草叶绒燃烧烟尘中共检测出111种成分，相对含量达63.89%～75.76%，艾叶绒燃烧烟尘中共检测出106种成分，相对含量达64.87%～75.50%。二者共鉴定出147种成分，其中共有成分10种。聚类分析把九牛草绒AS1、AS2、AS3和艾叶绒AA3聚为一类，九牛草绒AS4、AS5和艾叶绒AA5聚为一类，其余3种艾叶绒聚为一类。九牛草叶绒燃烧产生的甲醛、TVOC、PM2.5和PM10浓度均显著低于艾叶绒。结论：九牛草绒和艾叶绒燃烧烟尘中挥发性成分种类和含量存在差异：二者均含有较多烯类和烷类物质，九牛草叶绒烟中醇类物质含量略高于艾叶绒，而酚类物质含量远低于艾叶绒，仅在艾叶绒烟中检测到少量桉油精和龙脑。九牛草叶绒燃烧后室内空气污染物浓度均显著低于艾叶绒。 |
| English Summary: |
| To compare the volatile components in the smoke produced by burning moxa from Artemisia stolonifera and A.argyi with different germplasm resources，as well as the concentrations of indoor air pollutants，thereby providing scientific support for the further development and utilization of A.stolonifera.Methods:Headspace solid-phase microextraction combined with gas chromatography-mass spectrometry(HS-SPME-GC-MS) was used to detect the volatile components in the smoke of burned moxa，followed by cluster analysis of all volatile components.An air quality detector was employed to measure concentrations of formaldehyde，total volatile organic compounds(TVOCs)，PM2.5，and PM10 in indoor air after burning the moxa.Results:A total of 111 volatile components were detected in the smoke from A.stolonifera moxa，with relative content ranging from 63.89% to 75.76%.For A.argyi moxa，106 components were detected，with relative content of 64.87% to 75.50%.A total of 147 volatile components were identified between the two resources，with 10 shared components.Cluster analysis grouped A.stolonifera samples AS1，AS2，and AS3 with A.argyi sample AA3 into one cluster; A.stolonifera samples AS4 and AS5 with A.argyi sample AA5 into one cluster; the remaining A.argyi samples into a separate cluster.The concentrations of formaldehyde，TVOCs，PM2.5，and PM10 generated by burning A.stolonifera moxa were significantly lower than those of A.argyi moxa.Conclusion:The volatile components and their concentrations in the smoke of A.stolonifera moxa and A.argyi moxa exhibit distinct differences.Both contain a considerable amount of alkenes and alkanes.The smoke from A.stolonifera moxa had a slightly higher alcohol content but a much lower phenol content than A.argyi moxa，with only small amounts of eucalyptol and borneol detected in A.argyi moxa smoke.The indoor air pollutant concentrations after burning A.stolonifera moxa were significantly lower than those after burning A.argyi moxa. |
