Chemical Composition of Essential Oil from the Peel of Chinese Torreya grandis Fort

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%).
