title: The chemical composition and antimicrobial activity of the leaf oil of Cupressus lusitanica from Monteverde, Costa Rica.
abstract: The essential oils from the leaves of three different individuals of Cupressus lusitanica were obtained by hydrodistillation and analyzed by gas chromatography - mass spectrometry. A total of 49 compounds were identified in the leaf oils. The major components of C. lusitanica leaf oil were α-pinene (40%-82%), limonene (4%-18%), isobornyl acetate (up to 10%) and cis-muurola-4(14),5-diene (up to 7%). The essential oil was screened for antimicrobial activity, and it showed antibacterial activity against Bacillus cereus and antifungal activity against Aspergillus niger.
