Abstract

Abstract The chemotaxonomy of Moroccan rosemary was studied. The essential oil, which was obtained by hydrodistillation of Rosmarinus officinalis L. from different regions of Morocco (Rabat, Taforalt and Elateuf) was analyzed by GC and GC/MS. The variations in chemical composition are important between plant populations. We have defined three chemotypes of R. officinalis: the α-pinene-chemotype (α-pinene, 37–40% of the oil), the camphor-chemotype (camphor, 41–53% of the oil) and the 1,8-cineole-chemotype (1,8-cineole, 58–63% of the oil). The chemical composition of the 1,8-cineole-chemotype of R. officinalis was analyzed by GC and GC/MS. A total of 91 constituents were identified. The effect of harvest time on the oil production and chemical composition was examined on R. officinalis, and R. eriocalyx Jordan et Fourr., which were collected in the eastern Morocco from Elateuf and Debdou regions at different vegetative stages (from January to July). At full flowering, the oil yield was particularly high (1.6 % for R. officinalis and 1.9 % for R. eriocalyx). It was much lower for early or late flowering. The chemical composition of oils does not seem to be a function of the species differentiation or harvest time. 1,8-Cineole (48,9–56,3%) was the main component of the oils of both species.

摩洛哥迷迭香油的研究

摘要对摩洛哥迷迭香进行了化学分类研究。采用气相色谱(GC)和质谱联用(GC/MS)对产自摩洛哥拉巴特(Rabat)、塔福拉尔特(Taforalt)和埃拉特夫(Elateuf)不同地区的迷迭香(rosmarus officinalis L.)挥发油进行了分析。植物种群间化学成分的差异很重要。我们定义了三种化学型:α-蒎烯-化学型(α-蒎烯，占油的37-40%)、樟脑-化学型(樟脑，占油的41-53%)和1,8-桉叶油脑-化学型(1,8-桉叶油，占油的58-63%)。采用气相色谱(GC)和质谱(GC/MS)分析了山茱萸中1,8-桉叶油脑化学型的化学成分。共鉴定出91个成分。研究了不同采收时间对山茱萸和山茱萸产油量和化学成分的影响。在摩洛哥东部Elateuf和Debdou地区不同的营养阶段(1月至7月)采集。盛花期的产油率最高，达1.6%和1.9%。早花期和晚花期则要低得多。油的化学成分似乎不是物种分化或收获时间的函数。1,8-桉树脑(48,9 - 56,3%)是两种植物精油的主要成分。

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
