Abstract

Acinos is a small genus of economically important plants belonging to Lamiaceae family whose botanical collocation is quite problematic due to the disagreement among the botanists and the presence in literature of several names and synonyms from different sources. In the present study the chemical composition of the essential oil from aerial parts of Acinos alpinus subsp. nebrodensis (Strobl) Brullo & Brullo collected in Central Sicily was analyzed by GC-MS. The result showed the presence of large quantity of sesquiterpene hydrocarbons with germacrene D (37.9%) as the most abundant component followed by (E)-β-caryophyllene (5.1%). Among the oxygenated monoterpenes thymol (8.3%) was the most abundant; good quantity of hexadecanoic acid (6.8%) was also observed. Chemotaxonomic considerations with respect all the other oils of Acinos taxa, studied so far, were carried out.

摘要

Acinos是属于唇形科的经济上重要植物的一个小属，由于植物学家之间的分歧以及文献中存在来自不同来源的多个名称和同义词，其植物搭配存在很大问题。在本研究中，来自Acinos alpinus subsp.地上部分的精油的化学成分。通过 GC-MS 分析在西西里中部收集的nebrodensis (Strobl) Brullo & Brullo。结果表明存在大量倍半萜烃，其中以germacrene D（37.9%）为最丰富的组分，其次是（E）-β-石竹烯 (5.1%)。在含氧单萜中，百里香酚（8.3%）含量最多；还观察到大量的十六烷酸（6.8%）。对迄今为止研究的所有其他Acinos taxa 油进行了化学分类学考虑。
