市售沉香精油气质联用分析方法研究

Study on GC-MS analysis of agarwood essential oils from market

采用气质联用技术对市场上某沉香精油的成分进行了分析,通过对比研究探索了一种分离效果较好的色谱柱程序升温方法。研究发现,市售沉香精油中可分离的成分达100余种,其中可通过质谱数据库识别的且含量大于0.1%的组分有57种,色酮类化合物总含量为24.2%,沉香螺醇含量为15.1%。

The constituents of the certain kind of agarwood essential oil from the market were analyzed with GC-MS in the paper.The programmed temperature rising condition of a chromatographic column with better separation effect was explored through comparative study.The study finds that there are more than 100 components in the agarwood essential oils from the market, which can be identified by mass spectrometry database.There are 57 components with more than 0.1% content that can be identified by mass spectrometry database, the total content of chromone compounds is 24.2%,and the content of chalone is 15.1%.
