目的:分析沉香种子的挥发性成分。方法:采用超临界CO2流体萃取技术,提取沉香种子中的挥发性成分,经气相色谱-质谱(GC-MS)分析,结合NIST数据库查询,鉴定化合物结构。结果:经GC-MS分析,分离得到沉香种子中25个化学成分,鉴定了22个,其中棕榈酸乙酯的含量最高,为28.26%,4-甲基-1-(1,5-二甲基)-苯含量为10.22%,棕榈酸甲酯的含量为8.09%,莰烯含量为7.26%。结论:超临界CO2萃取法是提取沉香种子提取物较为理想的方法。
OBJECTIVE: To analyze the volatile components of agarwood seeds. Methods: The volatile components were extracted from the seeds by supercritical CO2 fluid extraction. The compounds were identified by gas chromatography-mass spectrometry (GC-MS) and NIST database. RESULTS: Twenty-five compounds were identified from 22 seeds by GC-MS. The content of ethyl palmitate was 28.26%, and the content of 4-methyl-1- ) -benzene content of 10.22%, methyl palmitate content of 8.09%, Camphene content of 7.26%. Conclusions: Supercritical CO2 extraction is an ideal method for extracting agarwood seed extract.
