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.

Essential oils isolated by hydro-distillation from the fruits and leaves of Zanthoxylum nitidum (Roxb.) DC (Rutaceae), growing in upper Assam region of North-East India were analyzed by GC and GC-MS. The fruit volatile oil contained 17 components amongst which 75\% were monoterpenes, 12.5\% were sesquiterpenes and 12.5\% were straight chain hydrocarbons; whereas the leaf volatile oil contained 16 components out of which 60\% were monoterpenes, 13.3\% were sesquiterpenes, and 26.7\% were straight chain hydrocarbons. Linalool (23.3\%), limonene (12.9\%), 6-terpineol (8.3\%), 6-pinene (7.9\%) were the predominant monoterpenes of the fruit oil and the main monoterpenes in the leaf oil were limonene (33.1\%), geraniol (10.6\%) and carvone (9.6\%).
