Chemical analysis of the volatile oil of Stachys Spectabilis using carbon nanotube profile- a new work

Multi-wall carbon nanotubes (MWCNTs) were used for he first time to extract the volatile oil of the Stachys spectabilis 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-nine different compounds major compound such as Benzaldehyde (30.69%), Caryophyllene oxide(10.53%), Trans- Caryophyllene (9.8%) and Chrysanthenyl acetate (6.22%) total compound identified is 97.17%. A comparison of the chemical composition of the oil was made with that of others methods on earial parts of Stachys spectabilis 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
