Chemical Composition and Antimicrobial Activities of Artemisia argyi Lévl. et Vant Essential Oils Extracted by Simultaneous Distillation-Extraction, Subcritical Extraction and Hydrodistillation

Abstract

Artemisia argyi Lévl. et Vant essential oil could be used as a good antimicrobial flavouring agent and applied in the food industry. In this study, three methods, including simultaneous distillation-extraction (SDE), subcritical extraction and hydrodistillation, were applied to extract A. argyi essential oil. Compared with subcritical extraction (1%) and hydrodistillation (0.5%), SDE gave a higher yield (1.2%). Components of the essential oils were analysed with gas chromatography-mass spectrometry (GC-MS), and the most abundant ingredients were caryophyllene oxide, neointermedeol, borneol, α-thujone and β-caryophyllene. These five components accounted for 82.93%, 40.90% and 40.33% for SDE, subcritical extraction, and hydrodistillation, respectively. Based on agar disc diffusion and minimum inhibitory concentration (MIC) assays, SDE oil showed a significant inhibitory effect towards Listeria monocytogenes, Escherichia coli, Proteus vulgaris, Salmonella enteritidis and Aspergillus niger. Furthermore, electron microscope observations (SEM) confirmed that SDE oil could obviously deform cell morphology and destroy the structure of cell walls. Performances showed that SDE was a promising process for extracting A. argyi essential oil with both high yield and antimicrobial activity.

Comparative Study on the Essential Oils from Five Wild Egyptian Centaurea Species: Effective Extraction Techniques, Antimicrobial Activity and In-Silico Analyses

“…EO yield variations are attributed to differences in the extraction method. Differences in environmental conditions may contribute to differences in EOs between the plant species [ 37 ].…”

Phytotoxic and Antimicrobial Activities of Teucrium polium and Thymus decussatus Essential Oils Extracted Using Hydrodistillation and Microwave-Assisted Techniques

“…This variation could also be ascribed to the method of extraction used [ 32 ]. Significant variations of the chemical compositions and antimicrobial activities were described among the extracted EOs of Artemisia argyi by HD, simultaneous distillation, and subcritical extraction techniques [ 46 ]. Moreover, the yield and composition of the EOs from Carum carvi , Anethum graveolens , and Pimpinella anisum were varied according to the method of extraction used [ 47 ].…”

Antimicrobial Carvacrol Incorporated in Flaxseed Gum-Sodium Alginate Active Films to Improve the Quality Attributes of Chinese Sea bass (Lateolabrax maculatus) during Cold Storage

“…The tested bacterial cells were treated with 1 × MIC carvacrol for 3 h and the cells were collected by centrifugation at 10142× g at 4 °C for 15 min, washed three times with 0.01 M PBS (PH 7.4). Then the treatment of cells and observations of SEM was followed by the reported study [26] using a SEM system (MIRA3, Tescan, Czech Republic).…”
