Abstract

The essential oils obtained by hydrodistillation of Pistacia atlantica Desf. leaves collected from different regions of Algeria were analyzed by GC and GC-MS. The essential oil was rich in monoterpenes and oxygenated sesquiterpenes. The major components were alpha-pinene (0.0-67%), delta-3-carene (0.0-56%), spathulenol (0.5-22%), camphene (0.0-21%), terpinen-4-ol (0.0-16%) and beta-pinene (0.0-13%). Among the various components identified, twenty were used for statistical analyses. The result of principal component analysis (PCA) showed the occurrence of three chemotypes: a delta-3-carene chemotype (16.4-56.2%), a terpinen-4-ol chemotype (10.8-16.0%) and an alpha-pinene/camphene chemotype (10.9-66.6%/3.8-20.9%). It was found that the essential oil from female plants (delta-3-carene chemotype) could be easily differentiated from the two other chemotypes corresponding to male trees.

摘要

对从阿尔及利亚不同地区采集的大西洋黄连木（Pistacia atlantica Desf.）叶片经水蒸馏得到的精油进行了气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）分析。该精油富含单萜和氧化倍半萜。主要成分有α-蒎烯（0.0 - 67%）、δ-3-蒈烯（0.0 - 56%）、匙叶桉油烯醇（0.5 - 22%）、莰烯（0.0 - 21%）、萜品-4-醇（0.0 - 16%）和β-蒎烯（0.0 - 13%）。在鉴定出的各种成分中，选取了20种用于统计分析。主成分分析（PCA）结果显示存在三种化学型：一种δ-3-蒈烯化学型（16.4 - 56.2%）、一种萜品-4-醇化学型（10.8 - 16.0%）和一种α-蒎烯/莰烯化学型（10.9 - 66.6%/3.8 - 20.9%）。研究发现，雌株的精油（δ-3-蒈烯化学型）能够很容易地与对应雄树的其他两种化学型区分开来。
