Eupatorium cannabinum subsp. corsicum (L.) is an endemic subspecies from the island of Corsica. The essential oil from the roots of this aromatic plant has been studied by GC, GC-MS and by 13C-NMR. In contrast to the essential oil from the aerial parts, which is dominated by hydrocarbon compounds (76.9%) and particularly by sesquiterpene components (43.3%), the essential oil from the roots was characterized by a high content of oxygenated compounds (61.0%), particularly oxygenated monoterpenes (54.0%). In the root oil, 106 components were identified representing 96.1% of the total amount. This oil was dominated by the monoterpenes esters (33%), the major components of which were neryl isobutyrate (17.6%), thymyl methyl oxide (15.1%), delta-2-carene (14.5%) and beta-pinene (5.7%). Aromatic esters, nerol derivatives (esters and diesters) and a benzofuran were investigated by GC-MS using different ionization modes including electron impact ionization, and positive- and negative-chemical ionization. These components have not previously been reported in the essential oil of aerial parts of E. cannabinum from Corsica island.
大麻叶泽兰亚种科西嘉变种（Eupatorium cannabinum subsp. corsicum (L.)）是来自科西嘉岛的一个特有亚种。已通过气相色谱（GC）、气相色谱 - 质谱联用（GC-MS）和碳 - 13核磁共振（13C-NMR）对这种芳香植物根部的精油进行了研究。与地上部分的精油不同，地上部分精油以碳氢化合物为主（占76.9%），特别是倍半萜类成分（占43.3%），而根部精油的特点是含氧化合物含量高（占61.0%），尤其是氧化单萜类（占54.0%）。在根油中，鉴定出106种成分，占总量的96.1%。该油以单萜酯类为主（占33%），其主要成分是异丁酸橙花酯（占17.6%）、氧化百里香酚甲酯（占15.1%）、δ-2-蒈烯（占14.5%）和β-蒎烯（占5.7%）。采用包括电子轰击电离以及正、负离子化学电离在内的不同电离模式，通过GC-MS对芳香酯类、橙花醇衍生物（酯类和二酯类）和一种苯并呋喃进行了研究。此前在科西嘉岛大麻叶泽兰地上部分的精油中尚未报道过这些成分。
