Abstract

The antibacterial activity of the essential oil from leaves of Juniperus phoenicea (Cupressaceae) and its chemical constituents were investigated in this study. The essential oil was obtained by hydro-distillation and analyzed by gas chromatography equipped with a flame ionisation detector (GC-FID), and gas chromatography coupled to a mass spectrometer (GC-MS). Sixty-three volatile compounds were identified representing 52 to 92% of the total oil compositions. The main monoterpenes were a-pinene (26.7-78.7%) and 6-3carene (7.6-15.4%). The antibacterial activity of J. phoenicea essential oil, when tested against both Gram-positive and Gram-negative bacteria, showed high activity against all bacteria tested, except Pseudomonas.

摘要

本研究对刺柏（柏科）叶精油的抗菌活性及其化学成分进行了研究。通过水蒸馏法获得精油，并采用配备火焰离子化检测器的气相色谱仪（GC-FID）和气相色谱-质谱联用仪（GC-MS）进行分析。共鉴定出63种挥发性化合物，占总油成分的52%至92%。主要单萜类化合物为α-蒎烯（26.7-78.7%）和β-蒈烯（7.6-15.4%）。刺柏精油对革兰氏阳性菌和革兰氏阴性菌进行测试时，除假单胞菌外，对所有测试细菌均表现出高活性。
