Abstract

Terminal branches from single male plants of Juniperus communis L. were collected in the Natura 2000 site ‘Serranía de Cuenca’, an environmentally valuable but depopulated area in the Iberian Peninsula, with the aim of studying the yield and composition of their essential oils. The results showed significant differences in terms of essential oil yield (0.15–0.53%) and composition of the collected samples. Unexpectedly, this variability was not related to the geographical origin of the plants. The main compounds detected were α-pinene (12.3–56.4%), β-phellandrene (10.0–29.8%) and limonene (3.4–25.7%). Samples stood out from those in other European areas because of their high content of β-phellandrene. Plant breeding programs could be useful in obtaining chemotypes and cultivars that ensure an adequate and stable essential oil composition. On the other hand, given that bioactivities depend on this composition, their high variability a priori enlarges their potential applications. This work is a starting point for identifying potential uses of common juniper that may enable economic, social and environmental alternatives for the development of this area.

自然 2000 保护区 "昆卡塞拉尼亚"（西班牙中部）中的杜松精油

在伊比利亚半岛环境价值高但人口稀少的自然保护区 "昆卡塞拉尼亚"（Serranía de Cuenca）采集了杜松（Juniperus communis L.）单株雄株的顶生枝条，目的是研究其精油的产量和成分。研究结果表明，所采集样本的精油产量（0.15%-0.53%）和成分差异很大。出乎意料的是，这种差异与植物的地理来源无关。检测到的主要化合物是 α-蒎烯（12.3-56.4%）、β-黄柏烯（10.0-29.8%）和柠檬烯（3.4-25.7%）。与其他欧洲地区的样本相比，该地区的样本因含有较高的β-黄柏烯而与众不同。植物育种计划有助于获得化学类型和栽培品种，以确保足够和稳定的精油成分。另一方面，由于生物活性取决于这种成分，它们的高变异性先验地扩大了它们的潜在应用范围。这项工作是确定普通刺柏潜在用途的一个起点，可以为这一领域的发展提供经济、社会和环境方面的替代方案。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
