Abstract

Today, the use of essential oils is increasing day by day, and it is considered as raw materials in many industries. Therefore, this study aims to identify the essential oil profile, antioxidant and antimicrobial activity of Rosa canina L. and Rosa pimpinellifolia L. reveal their potential use in the industry. Essential oils that were obtained in 2013-2014 from different parts (flower, leaf, stem, and fruit) of Rosa canina L. and Rosa pimpinellifolia L. by the hydro-distillation method were analyzed by GC/MS. The dominant components in Rosa canina L. were found as trans-geraniol in the flowers (42.08 % for 2013), linalool in the leaves (11.55 % for 2014), and stem (14.91 % for 2013) and vitispirane in the fruits (37.19 % for 2014). The dominant components in R. pimpinellifolia L. were found as heneicosane in the flowers (22.07 % for 2014), γ-elemene in the leaves (30.21 % for 2013), linalool in the stem (14.76 % for 2013) and the fruits, (E)-2-hexenal for those collected in 2013 (14.09 %). The IC₅₀ and FRAP values of the samples ranged from 127.54 to 142.22 μg/g and 121.43 to 296.78 μmol TE/g, respectively. According to the results obtained, both R. canina L. and R. pimpinellifolia L. were found to show poor antioxidant values of DPPH and FRAP. In general, it was determined that the essential oils obtained from different plant parts of both species had a moderate antimicrobial effect against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, and Pseudomonas aeruginosa.

摘要

如今，精油的使用量日益增加，被许多行业视为原料。因此，本研究旨在确定Rosa canina L. 和Rosa pimpinellifolia L.的精油成分、抗氧化和抗菌活性，揭示它们在工业中的潜在用途。2013-2014 年从Rosa canina L. 和Rosa pimpinellifolia L. 的不同部位（花、叶、茎和果实）通过水蒸馏法获得的精油通过 GC/MS 进行分析。Rosa canina L. 中的主要成分被发现为反式- 花中的香叶醇（2013 年为 42.08 %）、叶子中的芳樟醇（2014 年为 11.55 %）和茎中（2013 年为 14.91 %）以及果实中的葡萄吡喃（2014 年为 37.19 %）。R. pimpinellifolia L.的主要成分是花中的二十二烷（2014 年为 22.07 %）、叶中的 γ-榄香烯（2013 年为 30.21 %）、茎中的芳樟醇（2013 年为 14.76 %）和果实， ( E )-2-己烯醛用于 2013 年收集的那些 (14.09 %)。样品的IC ₅₀和FRAP 值分别为127.54 至142.22 μg/g 和121.43 至296.78 μmol TE/g。根据获得的结果，R. canina L. 和R. pimpinellifolia发现 L. 显示出较差的 DPPH 和 FRAP 抗氧化值。总的来说，确定从这两个物种的不同植物部分获得的精油对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌、蜡状芽孢杆菌和铜绿假单胞菌具有中等的抗菌作用。
