Abstract:

Volatile oils in leaves of three cypress species were extracted by hydrodistillation method and analyzed by gas chromatography/mass spectrometry. Sixty-four constituents were separated and identified. The majority of the components were found to be monoterpenes and sesquiterpenes. There were 33, 37, 37 compounds in the oils of leaves of Sabina chinensis (L.) Ant, Cupressus lusitanica ‘zhongshan’ Mill and Sabina chinensis (L.) Ant. Cv. Kaizuca, respectively. Fourteen compounds were common to them, which were thujene, α-pinene, camphene, sabinene, β-myrcene, α-terpinene, γ-terpinene, α-terpinolene, bornyl acetate, β-elemene, α-amorphene, germacrene D, δ-cadinene and elemol. In addition, each species had particular compounds. The main components were found to be: sabinene (20.99%), limonene (19.78%) and bornyl acetate (11.68%) for Sabina chinensis (L.) Ant; α-pinene (10.39%), sabinene (11.19%) and δ-3-carene (8.88%) for Cupressus lusitanica ‘zhongshan’ Mill; limonene (24.56%), β-myrcene (8.04%) for Sabina chinensis (L.) Ant. Cv. Kaizuca.
