中文摘要:

      目的 建立一种利用顶空固相微萃取-气相色谱-质谱法快速测定香紫苏香气成分的方法。方法 采用顶空固相微萃取-气相色谱-质谱联用技术, 对新疆香紫苏香气成分进行测定分析, 并采用面积归一化法计算各成分的相对含量。结果 共鉴定出18种化学成分, 主要成分为乙酸芳樟酯(79.58%)及芳樟醇(8.32%)。 结论 顶空固相微萃取与气相色谱-质谱联用技术具有样品用量少、前处理过程简单等优点, 适用于测定香紫苏香气成分。

英文摘要:

      Objective To establish a method for rapid determination of volatile aroma components in Salvia sclarea by headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Methods The volatile aroma components of Xinjiang Salvia sclareawere analyzed by means of headspace solid phase microextraction-gas chromatography-mass spectrometry, and the relative content of each component was calculated by area normalization method. Results A total of 18 chemical components were identified, and the main ingredients were linalyl acetate (79.58%) and linalool (8.32%). Conclusion Headspace solid phase microextraction and gas chromatography-mass spectrometry has the advantages of less sample consumption and simple pretreatment process, which is suitable for the determination of volatile aroma components in Salvia sclarea.
