Abstract

is an endemic species found only in Bulgaria. Its essential oil (EO) composition is unknown. This study assessed the EO yield and composition of as a function of the location and of drying prior to the EO extraction. was sampled from two natural habitats, Uzana and Shipka in the Balkan Mountains; the EO was extracted via hydrodistillation and analyzed on GC/MS. The plants from the two locations had distinct EO composition. The EO content (in dried material) was 0.18% (Uzana) and 0.26% (Shipka). Monoterpene ketones were the major group of the EO constituents. Also, hydrocarbons predominated in the EO from Shipka, and alcohols predominated in the EO from Uzana. The EO from Uzana had a greater concentration of menthone (56% vs. 17% from Shipka) and neomenthol (7.8% vs. 2.4%). Conversely, the EO from Shipka had greater concentrations of pulegone (50% vs. 20% from Uzana), limonene (10.1% vs. 2.6%), and germacrene D (3.4% vs. 1.1%). Drying prior to the EO extraction altered the concentration of some constituents. This is the first report of EO yield and composition. The EO showed some similarities with the chemical profile of other Micromeria species, but overall, it has an unique chemical profile and may have distinctive applications.

摘要

是保加利亚特有的地方种。其精油（EO）成分未知。本研究评估了作为地理位置和提取前干燥的函数的精油产量和组成。从巴尔干山脉的乌扎纳和希普卡两个自然栖息地中采集了，通过水蒸馏提取精油并通过 GC/MS 进行分析。两个地点的植物具有明显不同的精油组成。EO 含量（在干燥材料中）分别为 0.18%（乌扎纳）和 0.26%（希普卡）。单萜酮是精油主要成分。此外，Shipka 的精油中以烃类为主，而 Uzana 的精油中以醇类为主。Uzana 的精油中含有更高浓度的薄荷酮（56% 比 Shipka 中的 17%）和新薄荷醇（7.8% 比 Shipka 中的 2.4%）。相反，Shipka 的精油中含有更高浓度的薄荷酮（50% 比 Uzana 中的 20%）、柠檬烯（10.1% 比 Uzana 中的 2.6%）和大根香叶烯 D（3.4% 比 Uzana 中的 1.1%）。提取精油前的干燥改变了一些成分的浓度。这是关于精油产量和组成的首次报道。该精油与其他密花蒿属植物的化学特征有些相似，但总体而言，它具有独特的化学特征，可能具有独特的应用。
