Abstract

|
The compositions of essential oils isolated from the leaves and fruits of Chamaecyparis obtusa (Sieb. et Zucc). Endl. and Chamaecyparis pisifera (Sieb. et Zucc.) Endl. were analyzed through GC and GC-MS. The oil yields were 0.83% (as fresh weight) and 1.36% in the leaves and the fruits of C. obtusa, and were 0.92% and 1.28% in those of C. pisifera, respectively. More than 90 components were identified, including high contents of monoterpenoids and sesquiterpenoids. Contents of monoterpenoids in the leaf and fruit oils of C. pisifera were higher than in those of C. obtusa. The major constituents in the leaf oil of C. obtusa were sabinene (11.81% as determined through GC peak area), limonene (7.73%), bornyl acetate (6.92%), borneol+α-terpineol (15.67%), and elemol (12.82%), and those in the fruit oil were myrcene (8.12%), γ-terpinene (5.91%), ρ-cymene (7.62%), borneol+α-terpineol (6.53%), and β-caryophyllene (23.74%). The major constituents in the leaf oil of C. pisifera were α-pinene (32.34%), δ-3-carene (25.28%), myrcene (11.72%), and bornyl acetate (8.77%), and those in the fruit oil were α-pinene (29.38%), δ-3-carene (30.27%), myrcene (15.05%), and limonene (8.10%).
