Abstract:

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.

Key words: verivert oil, chemical composition, chemical structure
