Abstract

The composition of the peel essential oil of Torreya grandis fort obtained by cold pressing and steam distillation was determined by GC and GC/MS. 62 constituents accounting for 99.6% of the total pressed oil were identified while 59 compounds accounting for 99.4% of the steam distilled oil were identified. Limonene (35.6–37.1%), α-pinene (20.1–24.1%), and δ-carene (3.3–3.9) were the major constituents. Others include γ-carene (3.8-3.9%), germacrene D (2.5–2.9%), and β-farnesene (2.7-2.8%).
