The essential-oil compositions of one Croatian and three Serbian populations of Juniperus deltoides R.P.ADAMS have been determined by GC/MS analysis. In total, 147 compounds were identified, representing 97.3-98.3% of the oil composition. The oils were dominated by monoterpenes, which are characteristic components for the species of the section Juniperus. Two monoterpenes, α-pinene and limonene, were the dominant constituents, with a summed-up average content of 49.45%. Statistical methods were used to determine the diversity of the terpene classes and the common terpenes between the newly described J. deltoides populations from Serbia and Croatia. Only reports on several specimens from this species have been reported so far, and there are no studies that treat population diversity. Cluster analysis of the oil contents of 21 terpenes showed high correlation with the geographical distribution of the populations, separating the Croatian from the Serbian populations. The comparison of the essential-oil compositions obtained in the present study with literature data, showed the separation of J. deltoides and J. oxycedrus ssp. oxycedrus from the western Mediterranean region.
通过 GC/MS 分析,确定了克罗地亚和塞尔维亚的三个地区的 Juniperus deltoides R.P.ADAMS 的精油成分。总共鉴定出 147 种化合物,占油组成的 97.3-98.3%。这些油以单萜为主,这是该属植物的特征成分。两种单萜,α-蒎烯和柠檬烯,是主要成分,平均含量为 49.45%。统计方法用于确定萜类化合物的多样性和新描述的来自塞尔维亚和克罗地亚的 Juniperus deltoides 种群之间的共同萜类化合物。迄今为止,只有关于该物种的几个标本的报告,而且没有研究涉及种群多样性。对 21 种萜烯油含量的聚类分析显示,与种群的地理分布高度相关,将克罗地亚种群与塞尔维亚种群分开。本研究中获得的精油成分与文献数据的比较表明,Juniperus deltoides 和 J. oxycedrus ssp. oxycedrus 与西地中海地区分离。
