  • Constituents of the essential oil (EO)s and hydrosol of rosemary (Rosmarinus officinalis L.) and lavender (Lavandula angustifolia Mill.) were analyzed by gas chromatography-mass spectrometry (GC-MS). The identified major constituents were ${\alpha}$-pinene (40.96%), camphor (34.44%), verbenone (45.31%), and camphor (67.04%) in rosemary EO, lavender EO, rosemary hydrosol, and lavender hydrosol, respectively. The antioxidant activity of EO and hydrosol extracted from rosemary and lavender were evaluated. Both EO showed di(phenyl)-(2,4,6-trinitrophenyl) iminoazanium (DPPH) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) free radical scavenging activities as well as $Fe^{2+}$ ion chelating activity but no alkyl radical scavenging activity. Rosemary EO showed higher DPPH radical scavenging activity than lavender, whereas lavender EO showed higher $Fe^{2+}$ ion chelating activity. Both rosemary and lavender hydrosols showed alkyl radical scavenging activity, but only lavender hydrosol showed an activity on $Fe^{2+}$ chelating assay. Both rosemary and lavender hydrosols also protected the dermal fibroblast and the HaCaT keratinocytes against $H_2O_2$-induced cytotoxicity.

  • Recently, consumers using cosmetics have a great interest in raw material safety. Among them, interest in natural preservatives is increasing, and as the demand for cosmetics excluding paraben preservatives increases, a method of replacing synthetic preservatives with antibacterial essential oils is being considered. The antibacterial effect of essential oils depends on the components, concentrations and interactions between the main active compounds. Effective preservatives should have antimicrobial activity against a wide range of strains even at minimal concentrations. All preservatives should be considered to increase skin concentration and cause skin irritation and allergic reactions. Consumers recognize that essential oils from nature are safe, but some should be careful because they can cause contact allergies or phototoxic reactions. As such, it is important to balance natural preservatives with maximum preservative effects and low toxicity. This paper describes the characteristics of essential oils focused on antibacterial properties, efficacy and safety as cosmetic preservatives.

  • Magnolia kobus is known to exert various biological effects, such as antioxidant and hypnotic activity. In this study, we investigated the antimicrobial and anti-inflammatory activity of M. kobus essential oil extracted using steam distillation. Its antimicrobial activity was tested against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa by the paper disk diffusion and minimum inhibitory concentration (MIC) methods. Its anti-inflammatory activity was evaluated by measuring its inhibition ratio on the production of nitric oxide (NO) and PGE2 in lipopolysaccharide (LPS)-induced RAW264.7 cells. Its composition was analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that M. kobus essential oil exhibited excellent antibacterial activity against S. aureus, with a clear zone of 18 mm and an MIC value of 0.25 mg/ml. Its clear zones against P. aeruginosa and E. coli were 14 mm and 17 mm, respectively, while its MIC values were 1 mg/ml and 0.5 mg/ml, respectively. The essential oil exhibited no cytotoxicity to the RAW264.7 cells at a concentration of 500 ㎍/ml while showing NO (37.7%) and PGE2 inhibition (24.0%). Its three main fragrance ingredients identified were 3-carene (77.07%), β-elemene (6.92%), and caryphyllene (2.86%). The results suggest that M. kobus essential oil has potential as a cosmetic functional material with antimicrobial and anti-inflammatory effects.

  • This thesis tried applying Ayurvedic hair and scalp care program and analyzing its effect. Ayurvedic treatment strengthens our immunity through natural healing power. I measured with MIC test and Halo test in order to examine the antibacterial efficacy against colonies which reside in head, when Ayurvedic base oils and essential oils were used on hair and scalp. Finally, I reached the results as follows. I examined the antibacterial efficacy of base oils and essential oils against Bacillus subtilis and Propionibacterium acnes, based on the MIC test with 9 kinds of base oil and 18 kinds of essential oil. By way of experiment, base oils did not show the antibacterial efficacy from all colonies, and in case of essential oils, such as Chamomile, Clary sage, Jasmine, Neroli and Rose oil, the antibacterial efficacy against two colonies did not appear by the measure of below 5%. It turned out that Thyme, Geranium, Lavender and Tea tree had an high effect on two colonies. According to the Halo test which experimented on 7 kinds of bacteria with the essential oils like Geranium, Lavender and Thyme and with the base oils like Sesame and Coconut, it went to prove that base oils was inefficient on antibiosis. It was examined that all of essential oils had the effect on antibiosis from 7 kinds of bacteria. Thyme showed the best efficacy of antibiosis in the MIC and the Halo test.

  • We investigated the best antibiotics using blending oils after screening 11 kinds of essential oil known as antibiotics from plants. The minimum inhibitory concentration (MIC) and the minimum killing concentration (MBC) were found to be essential for essential oils B and E to inhibit target bacteria. All gram-positive bacteria containing S. aureus used in this experiment were shown highly antibiotic activity. And only A. baumanii in gram-positive bacteria and C. albicans in fungi were shown highly antibiotic activity. The essential oils used in our experiments showed better antibiotic activity compared to major studies using natural antibiotics with excellent antibiotic activity and essential oils from natural medicine. It is not known what mechanism of antimicrobial activity the essential oil used in the test has, but it is interpreted as a synthetic inhibitory mechanism of cell wall compared with other previous studies. From these results, it is expected that some substances or functional products with antibiotic activity will be developed.

  • Essential oils are fragrant oils extracted from the leaves, stems, peels, petals and roots of aromatic plants cultivated by natural means or using organic agricultural techniques. Essential oils have commonly been used as antibacterial and antifungal agents. In the present study, essential oil was extracted from lisianthus (Eustoma grandiflorum [Raf.] Shinn.) and tested for antifungal activities against three eumycetes (Penicillium pinophilum, Chaetomium glogosum and Aspergillus niger). Lisianthus essential oil showed high antifungal activities against three eumycetes, especially against Aspergillus niger, for which the resulting minimum inhibitory concentration (MIC) was 0.005 mg/ml. In addition, the extracted essential oil was shown to have antimicrobial activity against ten intestinal pathogenic bacteria (Escherichia coli, Salmonella typhimurium, Klebsiella pneumonia, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Pseudomonas aeruginosa, Bacillus subtilis, Enterococcus faecalis and Vibrio parahaemolyticus) according to the disc diffusion method and was also shown to exhibit strong antibacterial activity against an additional three pathogenic bacteria (Bacillus subtilis, Listeria monocytogenes and Vibrio parahaemolyticus). These results indicate that lisianthus essential oil could be used as an antibiotic against harmful bacteria that produce intestinal illnesses. From the present study, we suggest that lisianthus extracts can be utilized as potential antifungal and antibacterial agents and for the development of pharmaceutical and cosmetic products.

  • Acinetobacter baumannii is categorized as a red alert pathogen that is increasingly associated with a high mortality rate in infected patients because of its resistance to extensive antibiotics. This study evaluated the antibacterial activities of some essential oils (tee tree, rosemary, and lavender oils) against 18 clinical isolates of multidrug-resistant A. baumannii (MRAB). The carbapenemase screening Hodge test showed that all 20 strains of A. baumannii were resistant to imipenem. The identification of multidrug-resistant microbes was carried out using the VITEK system. The antimicrobial activity of essential oils was tested by a disk diffusion method against MRAB. In the disk diffusion method, tea tree showed the largest increase in inhibition size compared to lavender oil, and rosemary had no antibacterial effect. These results proved the antimicrobial effect of multidrug resistance A. baumannii. Tee tree oil would be a useful alternative natural product for the treatment and prevention of most common human pathogens and MRAB infections. This is expected to be used as an antimicrobial agent, such as hand disinfectant using natural essential oil in the future.
