In our present studies we identify the components of essential oil, crude extracts and fraction of Illicium verum, and evaluation of antibacterial activity. We isolated and identified as 3, 4-dihydroxybenzoic acid (protocatechuic acid) through spectroscopic studies and comparison with the data of the authentic sample [1]. The phase MEA itself was emerged as the active fraction comprising antibacterial, antioxidant and nematocidal constituents, including 3, 4-dihydroxybenzoic acid which also possessed antibacterial, Superb antioxidant and nematocidal activities [1].

The main objective of this study was to investigate the antibacterial activity and mechanism of Litsea cubeba essential oil (LCEO) against Acinetobacter baumannii. The antibacterial activity was examined by a serial dilution method and growth curves. The essential oil showed strong activity against A. baumannii. The mechanism of the antibacterial action was evaluated by the integrity and permeability of the membrane, scanning electron microscopy ( SEM) and SDS-PAGE. The change in permeability of the cell membrane and leakage of cell intracellular biomacromolecules verified that LCEO has an obvious effect on the cell membrane. SEM showed the damaging effect of the essential oil on cells since the morphology of the treated bacteria was significantly changed. Different expression of proteins indicated the effect of the essential oil on protein synthesis. It is suggested that LCEO with both emulsifying and antibacterial activities, has a potential to serve as an inhibitor against A. baumannii.

Increasing resistance of pathogens towards conventional antibiotics presents a major threat to public health because it reduces the effectiveness of antibiotic treatment. Mentha pulegium L., also known as pennyroyal, is an aromatic herb that belongs to the family Lamiaceae. Its essential oil has been traditionally used in medicine, aromatherapy, and cosmetics. The purpose of this work was to study the chemical composition of a pennyroyal essential oil and to evaluate their bioactivities, specifically, antioxidant, antimicrobial, anti-quorum sensing, and anti-inflammatory. A special focus was given to the antibacterial activity of the essential oil against Acinetobacter baumannii. The chemical composition of the essential oil was studied by GC-MS/GC-FID. The DPPH free radical scavenging assay and the β-carotene/linoleic acid system were used to evaluate the antioxidant properties. The antimicrobial and anti-quorum sensing activities were evaluated by disk diffusion assays and complemented with optical microscopy observations. The results showed that pulegone was the major compound (88.64%) of the pennyroyal essential oil. Regarding the antimicrobial activity, the action against Acinetobacter baumannii stands out, which, together with the capacity of the essential oil to inhibit the quorum sensing mechanisms, may suggest the use of the pennyroyal essential oil to further develop surface disinfectants for hospitals.

Introduction: The use of synthetic preservatives has been increasing in the food industry, and this leads to an increased incidence of gastrointestinal diseases and cancers in humans in the long run. Aims & Objectives: The aim of this study was to investigate the antibacterial and antioxidant activities of Nasturtium officinale essential oil on some important food borne bacteria. Materials & Methods: In this study, the antibacterial activity of N. officinale essential oil was evaluated on Staphylococcus aureus, Bacillus cereus, Escherichia coli and Salmonella enteric by microdilution method. Also, the antioxidant activity of this essential oil was evaluated by inactivating free radicals produced by 2,2-diphenyl-1-picrylhydrazyl (DPPH). Finally, the chemical compounds of the N. officinale essential oil were evaluated by gas chromatography- mass spectrometry (GC/MS). Results: The results showed that S. enteric and E. coli isolates had the most resistance and B. cereus isolates had the most susceptibility to N. officinale essential oil. The evaluation of antioxidant properties showed that in the same concentrations, the antioxidant effect of N. officinale was less than BHT. The obtained results from GC/MS showed that Phytol (30.20%) was the highest proportion and Megastigmatrienone 2 (0.18%) was the lowest proportion of essential oil. Conclusion: In general, the results of this study showed that N. officinale essential oil has an appropriate antibacterial activity against gram positive bacteria and can be used as a new antibacterial and antioxidant compound in the food industry.

Illicium verum is a small native evergreen tree of northeast Vietnam, India and southwest China. It is the flower of a medium-sized tree and is also known as star anise belongs to the family of Schisandraceae that grows in North America, Atlantic region, and tropical and subtropical zones of Asia. This study investigated the in vitro cytotoxic effects of essential oil obtained from the flowers of Illicium verum is also known as star anise. Steam distillation method was used to extract oil from the flowers of Illicium verum. Antioxidant activities such as DPPH (2,2-diphenyl-1-picrylhydrazyl), and ferric reducing power assays were assessed followed by total phenolic contents was estimated by folin-ciocalteau reagent method. Gas chromatography–mass spectrometry (GC-MS) analysis was used to find out volatile and semi-volatile compounds of essential oil extracted from Illicium verum. Anti-proliferative effect was studied by MTT assay method using MCF 7 and HepG 2 cancer cell lines. The maximum HepG 2 cell death was 25.73 ±0.24 % at 100µg/mL concentration and the IC50 was 194.32±0.24% at 100µg/mL concentration. The maximum MCF 7 cell death was 32.64±0.32% at 100µg/mL concentration and the IC50 was 153.18 ± 0.32% at 100µg/mL concentration.

Essential oils of Origanum majorana L. (marjoram), Illicium verum Hook. f. (star-anise) and Cinnamomum zeylanicum Blume (cinnamon) were obtained by steam distillation using a modified Clevenger device. The antimicrobial activity of each oil was evaluated against the bacteria Staphylococcus aureus, Escherichia coli and the fungi Aspergillus flavus and Aspergillus parasiticus by observing their growth and/or mycelial inhibition through comparison with the standard dish (without oil). The essential oils were analyzed using a gas chromatograph coupled to a mass spectrometer for identification and coupled to a flame ionization detector for quantification. The major constituents of marjoram, star-anise and cinnamon essential oils were 4-terpineol, trans-anetole and cinnamic aldehyde, respectively. In in vitro tests, essential oils of marjoram and cinnamon promoted an inhibitory effect on the bacteria S. aureus and E. coli, while the essential oil of star-anise presented activity only against E. coli. Marjoram, star-anise and cinnamon oils were effective against the studied fungi, presenting an inhibitory effect. The minimal inhibitory concentration for the mycelial growth of A. parasiticus was 1 and 0.01 µL mL-1 for star-anise and cinnamon oils, respectively. The minimal inhibitory concentration for A. parasiticus was 0.25, 2 and 2 µL mL-1 for cinnamon, star-anise and marjoram oils, respectively.
