蒸馏法提取香根油成分的GC-MS分析

Comparison of Chemical Compositions between Two Essential Oils from Vetiveria zizanioides by Different Extraction Methods

为研究蒸馏法香根油化学成分,以气相色谱-质谱联用仪检测水蒸馏法香根油,在香根油中鉴定发现异丁香酚等21种化学成分的化学结构,其中有5-甲基糠醛等12种化合物是香根油中首次发现的天然化合物,该发现对以香根油为原料的新食品添加剂研发及应用具有重要意义。

The chemical compositions of essential oil extracted from Vetiveria zizanioides by distillation method and organic solvent extraction method were analyzed by using GC-MS and compared. There are 21 kinds of compounds such as isoeugenol etc. isolated and identified in the two essential oils. The verivert oil obtained by distillation method contains 2 terpenoid compounds, accounting for 12.68%, but the verivert oil obtained by organic solvent extraction method contains 13 terpenoid compounds, accounting for 18.6%. There are more alcohols and ketones in the later, which meets the demands of international market much more. Both the two verivert oil contain isoeugenol, vanillin analogues, furfural analogues, guaiacol analogues, dihydrobenzofuran and 3-methyl-N- phenyl-pyrrole-2,4-diketone.
