The essential oil constituents, antimicrobial properties, and biosystematic characteristics (morphological, palynological, and anatomical features) of six species from different regions of Turkey were investigated qualitatively and quantitatively in this study. The chemical composition of the essential oils of dried aerial parts of species, i.e., , , , , , and were analyzed by GC-MS. The main constituents of the six species studied were 1,8-cineol, caryophyllene oxide, spathulenol, and borneol in different ratios. The antimicrobial activity of the essential oil extracted from the aerial parts of species of the genus was tested by the disc diffusion method. The essential oils of species showed different antimicrobial activity against the studied microorganisms. The highest antimicrobial activity against was observed in and the highest antimicrobial activity against was observed in . The morphology of the stem, leaf, bract, and flower structures of the species were analyzed in this study. Anatomical investigations focused on the root, petiole, and stem in more detail. Our research has broadened the criteria of anatomical characters unique to the species. Under light microscopy, the pollen grains of the six species belonging to were isopolar and radially symmetrical. The properties of the essential oil constituents, antimicrobial properties, and biosystematic data obtained in this study contribute to the bioactive and biosystematic studies of species used for food, pharmaceutical, and cosmetic purposes.
本研究对来自土耳其不同地区的六个物种的精油成分、抗菌特性及生物系统特征（形态学、孢粉学和解剖学特征）进行了定性和定量研究。通过气相色谱-质谱联用仪（GC-MS）分析了这六个物种，即[物种名称1]、[物种名称2]、[物种名称3]、[物种名称4]、[物种名称5]和[物种名称6]干燥地上部分精油的化学成分。所研究的六个物种的主要成分是1,8-桉叶素、氧化石竹烯（石竹烯氧化物）、匙叶桉油烯醇和冰片，其比例各不相同。采用纸片扩散法测试了从[属名]属物种地上部分提取的精油的抗菌活性。这六个物种的精油对所研究的微生物表现出不同的抗菌活性。观察到[物种名称7]对[微生物名称1]的抗菌活性最高，[物种名称8]对[微生物名称2]的抗菌活性最高。本研究分析了这六个物种的茎、叶、苞片和花结构的形态。解剖学研究更详细地聚焦于根、叶柄和茎。我们的研究拓宽了[属名]属物种特有的解剖学特征标准。在光学显微镜下，属于[属名]的六个物种的花粉粒是等极的且呈辐射对称。本研究获得的精油成分特性、抗菌特性及生物系统数据有助于用于食品、制药和化妆品用途的[属名]属物种的生物活性和生物系统研究。
