Antimicrobial Activity of Essential Oils from Two Ornamental Plants

Abstract

This study evaluated the antimicrobial activity of essential oils from sweet basil and thyme plants. Plants subjected to different treatments during cultivation. The content of plants essential oils was examined by GC-MS and 21 different components were identified in sweet basil and 16 components were recognized in thyme essential oils. The major components of sweet basil essential oil were camphor and 2-propenoic acid while 1,8-cineole and borneol were the major components of thyme essential oil. The antimicrobial activity of sweet basil and thyme essential oil was assessed against Erwinia amylovora, Aspergillus flavus, Aspergills oryzae and Fusarium oxysporum using agar plates method. The results showed that the sweet basil essential oil obtained from (magnetic water treatment+ magnetic iron at a rate of 150 mg/Kg) gave the most potent inhibitory effect on the growth of Erwinia amylovora, Aspergillus flavus and Fusarium oxysporum. The most potent inhibitory effect was observed from the thyme essential oil obtained from (saltwater +magnetic iron at a rate of 150 mg/Kg). These results obtained the importance of essential oil impacts on inhibit growth of toxic microbes
