Abstract
The essential oils from male and female branchlets and from female cones of Cupressus torulosa D. Don were analyzed by capillary gas chromatography (GC) and GC–mass spectrometry (GC–MS), and their compositions were compared. The analysis of essential oils revealed fifty-five constituents comprising 89.65–99.05% of the essential oil composition. Monoterpene hydrocarbons (51.09–58.06%) and oxygenated monoterpenes (28.61–39.48%) were found to be the major group of the constituents. Predominant constituents were umbellulone (16.26–26.66%), terpinen-4-ol (0.10–19.64%), α-pinene (9.62–17.76%), limonene (13.27–14.56%), sabinene (5.87–14.33%), γ-terpinene (1.97–6.89%) and α-terpinene (1.95–5.31%).
