沙蒿挥发油种子油气质联用法(GC-MS)化学组成分析Artemisia desterorum Spreng Volatile Oil Seed Oil GC-MS Chemical Composition Analysis

摘要:
本研究以沙蒿籽为原料,采用水中蒸馏法得到沙蒿籽挥发油,分别采用石油醚溶剂萃取和超临界二氧化碳萃取的方法,得到沙蒿籽种子油,并应用气质联用法(GC-MS)分析其化学组成。实验结果表明:沙蒿籽挥发性成分多为烯烃类或烯醇类化合物,其中含量最高的为β-罗勒烯以及它的同分异构体(相对含量为25.34%);其次是β-没药烯(相对含量为10.318%);D-柠檬烯含量也较高(相对含量为5.293%)。CO2超临界流体萃取所得沙蒿种子油中含有70.246%的亚油酸,13.433%的油酸和8.150%的棕榈酸。

In this study, the seed of Artemisia desterorum Spreng as the raw material, the volatile oil was extracted by water distillation, and the seed oil was extracted by petroleum ether solvent extraction and carbon dioxide supercritical fluid extraction, respectively. The chemical composition of volatile oil and seed oil was analyzed by GC-MS. The results showed that the volatile composition main consisted of olefins and enol, including β-basilene and its isomers (RA% = 25.34%), β-myrrhene (RA% = 10.318%), D-limonene (RA% = 5.293%). The chemical composition of seed oil extracted by CO2 supercritical fluid extraction was mainly linoleic acid (RA% = 70.246%), oleic acid (RA% = 13.433%) and palmitic acid (RA% = 8.150%).
