Hydrodistillated essential oils of Ziziphora clinopodioides ssp. rigida from nine populations of the Lashgardar protected region (Hamedan Province, Iran) were analyzed by using GC and GC/MS techniques to determine the intraspecific chemical variability. Altogether, 39 compounds were identified in the oils, and a relatively high variation in their contents was found. The main constituents of the essential oils were pulegone (0.7-44.5%), 1,8-cineole (2.1-26.0%), neomenthol (2.5-22.5%), 4-terpineol (0.0-9.9%), 1-terpineol (0.0-13.2%), neomenthyl acetate (0.0-7.1%), and piperitenone (0.0-5.4%). For the determination of the chemotypes and the intraspecific chemical variability, the essential oil components were subjected to cluster analysis (CA). The five different chemotypes characterized were Chemotype I (pulegone/neomenthol), Chemotype II (pulegone), Chemotype III (pulegone/1,8-cineole), Chemotype IV (neomenthol), and Chemotype V (1,8-cineole/4-terpineol).
从伊朗哈梅丹省拉什加尔达保护区的九个居群中提取狭叶薰衣草的水蒸馏精油，采用 GC 和 GC/MS 技术进行分析，以确定种内化学变异性。总共鉴定出 39 种化合物，发现它们的含量存在较大差异。精油的主要成分是侧柏酮（0.7-44.5%）、1,8-桉叶素（2.1-26.0%）、新薄荷醇（2.5-22.5%）、4-萜品醇（0.0-9.9%）、1-萜品醇（0.0-13.2%）、新薄荷醇乙酸酯（0.0-7.1%）和胡椒酮（0.0-5.4%）。为了确定化学型和种内化学变异性，对精油成分进行了聚类分析（CA）。确定了五个不同的化学型，分别是化学型 I（侧柏酮/新薄荷醇）、化学型 II（侧柏酮）、化学型 III（侧柏酮/1,8-桉叶素）、化学型 IV（新薄荷醇）和化学型 V（1,8-桉叶素/4-萜品醇）。
