An extraction method for the removal of five toxic aqueous essential oils (α-terpinene, γ-terpinene, linalool, α-terpineol, and α-terpinyl acetate) in Chamaecyparis obtusa (C. obtusa) by liquid-liquid extraction (LLE) and solid-phase extraction (SPE) combined with gas chromatography. The best LLE conditions were as follows: extraction solvent, 1-octanol, and an essential oil:1-octanol ratio of 7:3. The best SPE conditions were as follows: sorbent, C18; and washing and elution step solvents of 2 mL 1-octanol and 1 mL water, respectively. Under these conditions, of the five toxic aqueous compounds α-terpinene, γ-terpinene and linalool were not detected, and only small amounts of α-terpineol (6.75 ng/g) and α-terpinyl acetate (2.77 ng/g) were detected. GC-FID was used to detect the five toxic aqueous essential oils. |
