Extraction and identification of volatile oil constitutions of Stachys setifera using GC/MS and MWCNTs

Multi-wall carbon nanotubes (MWCNTs) were used for he first time to extract the volatile oil of the Stachys setifera stem bark through non-covalent interactions between the surface of MWCNTs and oil segments. Analyzing the absorbed volatile oil using GC and GC-MS showed that it is containing twenty-four different compounds major compound such as Piperitenone oxide (30.73%), Cinnamaldehyde (18.48%), Linalyl acetate (11.06%) and Borneol (4.30%) total compound identified is 98.36%. A comparison of the chemical composition of the oil was made with that of others methods on earial parts of Stachys setifera using nano tube and hydrodistillaion methods. MWCNTs were washed by water and organic solvents and they were used repeatedly. Results showed no sign of the decreasing the extraction capacity of MWCNTs after multiple cycles.
