Research of essential oil extraction efficiency improvement from Thujopsis dolabrata var. hondae using the underwater shock wave

抄録

The underwater shock wave selectively destroys the tracheid of the conifer by the effect of the spalling destruction, and forms the extraction road of an internal tree sap. The shock wave that is the instantaneous high pressure reaches the entire cell, and the effects are expected more than usual static pressures. As for the essential oil obtained by steaming distilling Hiba (Thujopsis dolabrata var. hondae) sawn wood, a variety of physiology revitalizations like the antibacterial activity and the effect etc. of insecticide of Hinokitiol that is the principal ingredient are admitted. As a preprocessing, treating the underwater shock wave to Hiba sawn wood, the essential oil is expected to be able to be extracted more highly effective than a usual steam distillation. In this research, the increasing of the amount of Hinokitiol included in the essential oil by the shock wave loading is reported.
