在意大利中部温带气候条件下，连续两个生长季节对十种纤维大麻（Cannabis sativa L）品种的挥发性成分进行了研究。采用水蒸气蒸馏法提取新鲜植物花序，采用气相色谱-质谱法对其精油进行表征。此外，利用SPME-GC-MS分析了新鲜植物花序自发散发的香气成分。研究了8株雌雄异株油菜的EO产量。其中，红叶柄、Pop 1、Pop 2、Pop 3、Pop 4、Pop 5和2个雌雄同株（Codimono和Felina 34）品种的α -蒎烯（3-20%）、β -蒎烯（1-8%）、E-ocimene（1-10%）、月桂烯（8-45%）和萜烯（0.12-22%）的产量在0.11% ~ 0.25% （w/w）之间。单萜烯的组成可用于区分雌雄异株品种。-石竹烯（7-28%）、α -葎草烯（3-12%）和氧化石竹烯（2-6%）是主要的倍半萜。四氢大麻酚（THC）仅在2005年栽培的两个雌雄异株品种的EOs中痕量存在。在几种分析品种的精油中未检测到大麻酚（CBN），而在几种分析品种中发现无致幻剂大麻二酚（CBD）是典型的挥发性成分。这些发现也被顶空气相色谱-质谱分析所证实。分析了从意大利中部种植的纤维大麻品种中获得的EOs，其特点是具有合法和安全的大麻素含量的有趣和特定的萜烯成分。它们是从新鲜植物的花序中获得的，通常是苜蓿L纤维品种的废料。本研究通过充分利用植物材料，利用其花序生产精油作为天然香料和香料添加剂，加强了大麻作为一种多用途作物的假设。(C) 2010 Elsevier B.V.版权所有
The volatile composition of ten fibre hemp (Cannabis sativa L) varieties was investigated during two successive growing seasons under temperate climatic conditions in Central Italy.The freshly plant inflorescences were hydrodistilled and the essential oils (EOs) were characterized by GC-MS. In addition, the composition of the aroma emitted spontaneously from the freshly plant inflorescences were analysed by SPME-GC-MS. The EO yields of eight dioecious (Carmagnola, CS., Red Petiole, Pop 1, Pop 2, Pop 3, Pop 4, Pop 5) and two monoecious (Codimono and Felina 34) cultivars ranged from 0.11 to 0.25% (w/w) and showed a significant production of alpha-pinene (3-20%), beta-pinene (1-8%), E-ocimene (1-10%), myrcene (8-45%) and terpinolene (0.12-22%).The monoterpene composition was useful to distinguish the monoecious cultivars from the dioecious ones. beta-Caryophyllene (7-28%), alpha-humulene (3-12%), and caryophyllene oxide (2-6%) were the main sesquiterpenes. Tetrahydrocannabinol (THC) was present in traces in the EOs of only two dioecious cultivars cultivated in 2005. Cannabinol (CBN) was not detected in the essential oils, while the no-hallucinogenous cannabidiol (CBD) was found as typical volatile constituent in several analysed cultivars. These findings were also confirmed by the headspace GC-MS analysis carried out on the same samples. The analysed EOs obtained from fibre hemp varieties cultivated in Central Italy were characterized by an interesting and specific terpene composition with a legal and safe cannabinoid content. They were obtained from freshly plant inflorescences, which usually represent a waste material from C. sativa L fibre varieties. The present study strengths the hypothesis to grow hemp as a multi-use crop through a complete utilization of the plant material using inflorescences to produce essential oils as natural flavour and fragrance additives.
