Abstract

Juniperus excelsa M.B subsp. Polycarpos (K.Koch), collected from south of Iran, was subjected to hydrodistillation using clevenger apparatus to obtain essential oil. The essential was analyzed by gas chromatography/mass spectrometry (GC/MS) and studied for antimicrobial, antifungal and antioxidant activities. The results indicated α-pinene (67.71%) as the major compound and α-cedral (11.5%), δ3-carene (5.19%) and limonene (4.41%) in moderate amounts. Antimicrobial tests were carried out using disk diffusion method, followed by the measurement of minimum inhibitory concentration (MIC). All the Gram positive and Gram negative bacteria were susceptible to essential oil. The oil showed radical scavenging and antioxidant effects.

摘要

从伊朗南部采集的卓越刺柏(Juniperus excelsa M.B subsp. Polycarpos (K.Koch)),使用克莱文杰装置进行水蒸馏以获得精油。对该精油进行气相色谱/质谱联用(GC/MS)分析,并研究其抗菌、抗真菌和抗氧化活性。结果表明,主要成分是α-蒎烯(67.71%),α-雪松烯(11.5%)、δ3-蒈烯(5.19%)和柠檬烯(4.41%)含量适中。采用纸片扩散法进行抗菌测试,随后测定最低抑菌浓度(MIC)。所有革兰氏阳性菌和革兰氏阴性菌均对该精油敏感。该精油具有自由基清除和抗氧化作用。
