Abstract

The chemical contents of the endemic Onosma malatyana roots collected from Malatya/Türkiye were determined using the hydrodistillation and the soxhlet methods and antimicrobial activity analysis of the extracts was also performed. The hydrodistillation method applied to the roots of O.malatyana resulted in identifying 31 compounds according to their retention times in GC-MS analysis. Additionally, crude ethyl acetate and crude oil etheric extracts of O.malatyana roots contained 14 compounds each. This research identified that the main component of the essential oil obtained by the hydrodistillation method was palmitic acid comprising 56.48% of the total composition. Additionally, in the crude petroleum etheric extract, oleic acid methyl ester (31.22%); and palmitic acid (24.69%) were identified as the main components in the crude ethyl acetate extract. The results of the antimicrobial activities indicated that O.malatyana root extracts were particularly effective against Gram-positive bacteria, specifically S. aureus and B. subtilis.

安纳托利亚地方性植物 Onosma malatyana（婆婆纳科）的精油和各种提取物的化学成分和抗菌活性。

采用水蒸馏法和索氏蒸馏法测定了从马拉蒂亚/图尔基耶采集的当地特有的 Onosma malatyana 根的化学成分，并对提取物进行了抗菌活性分析。根据 GC-MS 分析中的保留时间，采用水蒸馏法对 O.malatyana 的根进行提取后，确定了 31 种化合物。此外，O.malatyana 根的粗乙酸乙酯和粗油醚提取物各含有 14 种化合物。研究发现，通过水蒸馏法获得的精油的主要成分是棕榈酸，占总成分的 56.48%。此外，在粗石油醚提取物中，油酸甲酯（31.22%）和棕榈酸（24.69%）被确定为粗乙酸乙酯提取物中的主要成分。抗菌活性结果表明，O.malatyana 根提取物对革兰氏阳性菌特别有效，尤其是金黄色葡萄球菌和枯草杆菌。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
