在这项研究中,薄荷精油的功效,对Achilleaarabica和艾蒿植物进行了评估,以抵抗重要的土壤传播的真菌病原体,如黄萎病菌,solani根瘤菌,和尖孢镰刀菌.通过加氢蒸馏法从植物中获得精油,并通过气相色谱-质谱分析确定精油的化学成分。主要成分为哌啶酮氧化物(13.61%),哌啶酮氧化物(15.55%),pulegone(12.47%),1-薄荷酮(5.75%),和樟脑(5.75%),á-selinene13.38%,樟脑13.34%,L-4-萜品烯醇8.40%,(-)-á-Elemene7.01%,1,8-桉树脑4.71%,和(-)-spathulenol3.84%在A.arabica,和á-thujone(34.64%),1,8-桉树脑(19.54%),pulegone(7.86%),樟脑(5.31%),sabinene(4.86%),和苦艾曲霉中的germacrene-d(3.67%)。用接触效应法研究了0.05、0.1、0.25、0.5、1.00和2.00μl/ml浓度的油的抗真菌活性。M.longifolia油(1.00和2.00μl/ml)显示出显着的抗真菌作用,并对大丽花的菌丝生长具有100%的抑制作用,R.solani和F.尖孢。从这项研究中获得的结果可能有助于开发新的替代和安全的方法来对抗土壤传播的真菌病原体。
In this study, the efficacy of the essential oil of Mentha longifolia, Achillea arabica and Artemisia absinthium plants were evaluated against important soil-borne fungal pathogens as Verticillium dahliae, Rhizoctonia solani, and Fusarium oxysporum. Essential oils were obtained from plants by hydrodistillation method and the chemical components of essential oils were determined by analyzing by gas chromatography-mass spectrometry. The main components found as piperitone oxide (13.61%), piperitenone oxide (15.55%), pulegone (12.47%), 1-menthone (5.75%), and camphor (5.75%) in M. longifolia, á-selinene 13.38%, camphor 13.34%, L-4-terpineneol 8.40%, (-)-á-Elemene 7.01%, 1,8-cineole 4.71%, and (-)-spathulenol 3.84% in A. arabica, and á-thujone (34.64%), 1,8-cineole (19.54%), pulegone (7.86%), camphene (5.31%), sabinene (4.86%), and germacrene-d (3.67%) in A. absinthium. The antifungal activities of the oils were investigated 0.05, 0.1, 0.25, 0.5, 1.00, and 2.00 μl/ml concentrations with the contact effect method. M. longifolia oil (1.00 and 2.00 μl/ml) has displayed remarkable antifungal effect and provided 100% inhibition on mycelial growth of V. dahliae, R. solani and F. oxysporum. The results obtained from this study may contribute to the development of new alternative and safe methods against soil-borne fungal pathogens.
