摘要: 本研究旨在探索12C6+离子辐照茶树精油后,茶树精油活性成份的变化及其对口蹄疫病毒(foot-and-mouth disease virus,FMDV)的杀灭效果。采用50、100、150、200 Gy的12C6+离子束辐照茶树精油后,利用气相色谱-质谱联用仪(gas chromatography-mass spectrometer,GC-MS)法和红外色谱法分析辐照前后茶树精油主要成分变化及其质量沉积效应;检测茶树精油中松油烯-4-醇、1,8-桉叶素含量变化;将辐照前后茶树精油原液以及1:2、1:4辐照后稀释的精油注射50日龄成年鼠检测其临床用药的安全性;将稀释成1:2、1:4、1:6、1:8的辐照后茶树精油分别与等量的1:500的O-FMDV强毒充分混匀,皮下注射4~5日龄乳鼠,连续观察7 d,观察小鼠有无FMDV感染症状。试验结果表明,以100 Gy的12C6+离子束辐照茶树精油后,松油烯-4-醇含量由37.90%升高到39.03%,1,8-桉叶素含量无明显变化,羟基化合物含量明显增高;辐照前后茶树精油原液以及稀释后精油注射未见不良反应,辐照后茶树精油临床用药安全;乳鼠感染混有不同浓度的O-FMDV后,1:2、1:4稀释倍数的茶树精油组感染O-FMDV的乳鼠未出现死亡,注射部位未见炎症、坏死等,阳性对照组全部死亡。结果表明,12C6+离子束辐照茶树精油最佳剂量为100 Gy,在乳鼠体内抗O-FMDV效果的最大稀释度为1:4,12C6+离子束辐照可以提高茶树精油对FMDV的杀灭效果。

Abstract: The purpose of this study was to explore the changes of the active components of tea tree essential oil after 12C6+ ion injection and evaluate the killing effect of Foot-and-mouth disease virus (FMDV).Tea tree essential oil was irradiated by 12C6+ ion beam of 50,100,150 and 200 Gy,and the changes of main components and mass deposition effects of tea tree essential oil before and after irradiation were analyzed by gas chromatography-mass spectrometer (GC-MS) and infrared chromatography.The contents of terpinene-4-ol and 1,8-eucalyptin in tea tree essential oil were detected.The safety of tea tree essential oil before and after irradiation and the essential oil diluted by 1:2 and 1:4 irradiation were injected into suchling mice to detect the clinical use of tea tree essential oil. The irradiated tea tree essential oil diluted into 1:2, 1:4, 1:6 and 1:8 was thoroughly mixed with the same amount of O-FMDV at 1:500, respectively. The mice aged 4-5 d were subcutaneously injected and observed continuously for 7 d to observe whether the mice were infected with O-FMDV.The results showed that after irradiated tea tree essential oil with 100 Gy 12C6+ ion beam,the content of pinole-4 alcohol increased from 37.90% to 39.03%,the content of 1,8-eucalyptus had no significant change,and the content of hydroxyl compounds significantly increased after irradiated tea tree essential oil.The optimal irradiation dose was 100 Gy,and the tea tree essential oil with radiation dose of 100 Gy (the maximum dilution was 1:4) had the best anti-FMDV effect in suckling mouse.Irradiation of tea tree essential oil with a dose of 100 Gy could improve the killing effect of FMDV.
