Abstract

This work presents the results ofa study which concerns the influence of rotating magnetic field (RMF) on the antibacterial performance of commercial pine essential oil. A suspension of essential oil in saline solution and Escherichia coli were exposed to the rotating magnetic Afield (the frequency of electrical current supplied by a RMF generator f = 1-50 Hz; the averaged values of magnetic induction in the cross-section of the RMF generator B = 13.13 to - 19.92 mT, time of exposure t = 160 min, temperature of incubation 37 °C). The chemical composition of pine (Pinus sylvestris L.) essential oil was determined by gas chromatography coupled with mass spectrometry (GC-MS). The main constituents were α-pinene (28.58%), β-pinene (17.79%), δ-3-carene (14.17%) and limonene (11.58%). The present study indicates the exposition to the RMF, as compared to the unexposed controls causing an increase in the efficacy of antibacterial properties of pine oil. We have shown that rotating magnetic fields (RMF) at a frequency, f, between 25 Hz to and 50 Hz increased the antimicrobial efficiency of oil a concentration lower than 50%.

摘要

这项工作展示了一项研究的结果，该研究关注旋转磁场（RMF）对商业松油抗菌性能的影响。将松油悬浮液置于盐溶液中，并使大肠杆菌暴露于旋转磁场中（由 RMF 发生器提供的电流频率为 f=1-50 Hz；RMF 发生器横截面上的平均磁感应强度为 B=13.13 至-19.92 mT，暴露时间为 t=160 分钟，孵育温度为 37°C）。通过气相色谱-质谱联用仪（GC-MS）确定了松木（Pinus sylvestris L.）精油的化学成分。主要成分是α-蒎烯（28.58％）、β-蒎烯（17.79％）、δ-3-蒈烯（14.17％）和柠檬烯（11.58％）。与未暴露的对照组相比，本研究表明，暴露于 RMF 会导致松油的抗菌性能增强。我们已经表明，频率为 f 为 25 Hz 至 50 Hz 的旋转磁场会增加低于 50％浓度的油的抗菌效率。
