Ionic Liquid-Assisted Extraction of Essential Oils from Thujopsis dolobrata (Hiba).

ABSTRACT: Aomori hiba (Thujopsis dolobrata) has been used as a building material for centuries because of the wood's resistance against fungi and termites. In addition, the essential oil of hiba wood has a relaxing woody fragrance and antifungal properties and is composed mainly of (-)-thujopsene, cedrol, and hinokitiol. Steam distillation is the main industrial method for obtaining the oil but requires large amounts of water and heating energy. The present study describes the use of a cellulose-dissolving [C₂mim][(MeO)(H)PO₂] ionic liquid (IL) for efficient extraction of hiba oil. As a control method, organic solvent extraction using either hexane, Et₂O, or EtOAc was conducted at 80 °C for 1 h. The method developed in this study using an IL was conducted at t
