| Abstract: | The essential oils of fresh fruits and terminal branchlets with adherent leaves (leaves) of Platycladus orientalis (L.) Franco, growing wild in Iran, were analyzed by GC-MS, and screened for bacteriostatic and fungistatic activities (MIC determination). Eighteen components were identified in the essential oils. The major constituents of both cases were a-pinene, sabinene, 3-carene, limonene and cedrol. The essential oil of leaves has no antimicrobial activity, while the essential oil from fruit showed a modest and slightly antimicrobial activity against Bacillus subtilis, Candida albicans and Escherichia coli, Staphylococcus aureus, respectively. The defatted ethanol extract of leaves and fruits were rich in flavonoids and tannins. |
