Abstract
Stachys germanica L. (Lamiaceae) is a plant associated with a rich history in the traditional medicine of Iran, Turkey, and Serbia. However, researchers have not fully investigated the pharmacological potential of the herb, and scientific data on this plant species are limited. The aim of the current study was to evaluate the chemical composition of the essential oil (EO) obtained from the aerial parts of S. germanica L. growing wild in Bulgaria and to perform a comparative analysis of the chemical composition of EOs obtained from the same plant species from other geographical regions. For the evaluation of the chemical profile of the isolated EO, gas chromatographic analysis with mass spectrometry was performed. The most abundant terpene class was oxygenated monoterpenes, which accounted for 59.30% of the total EO composition. The bicyclic monoterpene camphor, as a compound of this class, was identified as the major constituent in the EO, accounting for 52.96% of the total oil composition. The chemical profile of Bulgarian EO is quite different compared to that of EOs from other regions. It is the only one to contain more than 50% camphor. In addition, EO contains significant amounts of the diterpene geranyl p-cymene (10.49%). This is the first study describing the chemical composition of EO from Bulgarian Stachys germanica L., and our results reveal some future perspectives for the evaluation of the biological activity of EO from the studied plant species as a new therapeutic agent or natural remedy targeting different medical conditions. The EO has a promising potential to be used as a biopesticide and repellent as well, an environmentally friendly and safer alternative to standard pesticides.
德国Stachys germanica L.（Lamiaceae）是一种在伊朗、土耳其和塞尔维亚的传统医学中有着丰富历史的植物。然而，研究人员尚未充分研究这种草药的药理潜力，关于这种植物的科学数据也有限。本研究的目的是评估从保加利亚野生生长的德国小蠊地上部分获得的精油（EO）的化学成分，并对从其他地理区域的相同植物物种获得的EO的化学成分进行比较分析。为了评估分离的EO的化学性质，进行了质谱气相色谱分析。最丰富的萜烯类是含氧单萜烯，占EO总组成的59.30%。双环单萜樟脑作为这类化合物，被确定为EO中的主要成分，占总油成分的52.96%。保加利亚EO的化学特征与其他地区的EO相比有很大不同。它是唯一一种含有50%以上樟脑的植物。此外，EO中还含有大量的二萜香叶基对cymene（10.49%）。这是首次描述保加利亚斯泰西属植物EO的化学成分。，并且我们的结果揭示了评估所研究的植物物种的EO作为一种新的治疗剂或针对不同医疗条件的天然药物的生物活性的一些未来前景。环氧乙烷作为一种生物杀虫剂和驱避剂，是一种对环境友好、更安全的标准杀虫剂替代品，具有很好的潜力。
期刊介绍：
International Journal of Analytical Chemistry publishes original research articles that report new experimental results and methods, especially in relation to important analytes, difficult matrices, and topical samples. Investigations may be fundamental, or else related to specific applications; examples being biological, environmental and food testing, and analysis in chemical synthesis and materials processing.
As well as original research, the International Journal of Analytical Chemistry also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
