Abstract

The essential oils of the fruits and the leaves of pistachio (Pistacia vera L.) were analyzed by GC and GC/MS. Fresh unripe pistachio fruits were richer in essential oil (0.5%, w/w) than the leaves (0.1%, w/w). Twenty one compounds were identified in the essential oil of the fruits and the major components were (+)-alpha-pinene (54.6%) and terpinolene (31.2%). The enantiomeric ratio of the major constituents of the essential oil of the fruits was determined using chiral GC/MS and it was found that the (+)/(-)-alpha-pinene ratio was 99.5:0.5, (+)/(-)-limonene 80:20, (+)/(-)-beta-pinene 96:4, and (+)/(-)-alpha-terpineol 0:100. Thirty three compounds were identified in the essential oil of the leaves and the major components were found to be alpha-pinene (30.0%), terpinolene (17.6%) and bornyl acetate (11.3%).

摘要

采用气相色谱(GC)和气相色谱 - 质谱联用(GC/MS)对阿月浑子(Pistacia vera L.)果实和叶片的精油进行了分析。新鲜未成熟的阿月浑子果实的精油含量(0.5%,w/w)高于叶片(0.1%,w/w)。在果实精油中鉴定出21种化合物,主要成分是(+)-α-蒎烯(54.6%)和萜品油烯(31.2%)。使用手性GC/MS测定了果实精油主要成分的对映体比例,发现(+)/(-)-α-蒎烯比例为99.5:0.5,(+)/(-)-柠檬烯为80:20,(+)/(-)-β-蒎烯为96:4,(+)/(-)-α-松油醇为0:100。在叶片精油中鉴定出33种化合物,主要成分是α-蒎烯(30.0%)、萜品油烯(17.6%)和乙酸冰片酯(11.3%)。
