Hippuris vulgaris, also known as horsetail or marestail, is a freshwater macrophyte occurring in lakes, rivers, ponds and marshes. According to 'The IUCN Red List of Threatened Species', H. vulgaris is at a high risk of extinction in Italy in the medium-term future. In the present study, we analysed for the first time the volatile composition of H. vulgaris growing in central Italy. For the purpose, the essential oil was obtained by hydrodistillation and analysed by GC-MS. The chemical composition was dominated by aliphatic compounds such as fatty acids (26.0%), ketones (18.7%) and alkanes (11.4%), whereas terpenoids were poorer and mostly represented by diterpenes (7.4%). n-Hexadecanoic acid (25.5%), hexahydrofarnesyl acetone (17.5%) and trans-phytol (7.4%) were the major volatile constituents. These compounds are here proposed as chemotaxonomic markers of the species.
问荆，也被称为木贼或马尾草，是一种生长在湖泊、河流、池塘和沼泽中的淡水大型植物。根据《世界自然保护联盟濒危物种红色名录》，问荆在意大利中期面临着高灭绝风险。在本研究中，我们首次分析了生长在意大利中部的问荆的挥发性成分。为此，通过水蒸馏法获得精油，并采用气相色谱 - 质谱联用仪进行分析。其化学成分以脂肪酸（26.0%）、酮类（18.7%）和烷烃（11.4%）等脂肪族化合物为主，而萜类化合物含量较少，主要以二萜类（7.4%）为代表。正十六烷酸（25.5%）、六氢法呢基丙酮（17.5%）和反式叶绿醇（7.4%）是主要的挥发性成分。这些化合物在此被提议作为该物种的化学分类学标记。
