  • The essential oils from the roots of Codonopsis lanceolata and the cultivated callus were analysed and compared by gaschromatography-mass spectrometry. In the experimental study of cell culture, it appeared that 2,4-dichlorophenoxy acetic acid in the culture medium induced higher production of essential oils in the callus than indole acetic acid. The growth of callus was inhibited by illumination of the light. The production of essential oil in cultured cells was increased by the addition of biosynthetic precursors. The essential oils from the roots of Codonopsis lanceolata and the cultured callus showed different compositions. Tetradecanoic acid, 1,1,-dimethoxyl 4-methoxy phenol, 9,12-octadecanoic acid and hexadecanoic acid were identified as main components of the cultured callus oil.

  • We have evaluated the combined antifungal effects of the essential oil from Eucalyptus globulus or its main component 1,8-cineole with ketoconazole. Checkerboard microtiter tests were used to analyze their effects against three Candida and six Trichophyton species. The susceptibility of the Trichophyton species to E. globulus essential oil differed distinctly. The fractional inhibitory concentration indices (FICIs) against the tested Candida species ranged between 0.09 and 0.38 for ketoconazole combined with E. globulus essential oil or 1,8-cineole, indicating significant synergism between ketoconazole and the oil samples. Similar experiments using Trichophyton species resulted in FICIs between 0.28 and 0.63, indicating relatively weaker combined effects than those observed with Candida species. Thus, the data reported here show that the anti-Candida effects of ketoconazole can be significantly improved in the presence of E. globulus essential oil or 1, 8-cineole.

  • In order to find out an anticariogenic substance, antibacterial activities of some medical herbs and spices against Streptococcus mutans were investigated. The essential oils of oregano, thyme, sage, fennel, nutmeg, rosemary, calamus and cassia cortex were shown antibacterial effect against S. mutans. The essential oil of oregano among other tested medical herbs and spices showed the most active antimicrobial activity. The essential oil of oregano inhibited the activity of glucosyltransferase from S. mutans. The minimal inhibition concentration of oregano essential oil was determined as 0.05nl/ml. The activity of glucosyltransferase from S. mutans was inhibited in the presence of oregano essential oil.

  • 쑥으로부터 추출한 정유를 Escherichia coli, Bacillus subtilis , Pleurotus ostreatus , Fusarium solani , Aspergillus nidulans에 첨가한 후 배양한 결과 다음과 같은 결과를 얻었다. 쑥의 정유를 첨가한 후 미생물을 배양시킨 결과 Escherichia coli,는 무반응이었으나 Bacillus subtilis , Pleurotus ostreatus , Fusarium solani , Aspergillus nidulans는 생육이 저해되었다. bacillus subtilis는 대조군에 비해 정유의 농도가 10~100ppm에서 10배의 생육저해를 나타냈다. 쑥의 정유는 또한 곰팡이에서 강한 생육저해를 나타냈으며 Pleurotus ostreatus는 1,000ppm의 농도에서 생육이 완전히 정지되었다.

  • 1. All Essential oils have antibacterial properties. 2. Essential oils reduce contamination. 3. Most of essential oils acts as an antofungal, antiviral, antiparasitic, antimicrobial agent and antioxidants. 4. They contain anions, ozone, and oxygenating molecules. 5. It is belueved that they take chemicals and metallices out of the air by breaking the molecular chain. 6. In France, it was reported that various essential oils prevent a side effect of radiation. 7. The essential oils travel via the olfactory nerve stimulating a emotional and phychological response that is believed to be responsible for releasing genetic blue priting from the cells thus releasing emotional trauma.

  • To develop a new effective and safe natural antibiotics and antioxidant the essential oil was extracted from the roots of Anthriscus sylvestris by steam distillation. Its composition was analyzed by GC-MS. The activities of the essential oil fraction and its main components were evaluated against antibiotic-susceptible and -resistant strains of some food-born bacteria. In addition the synergism was examined with this oil combined with antibiotic by checkerboard titer test. The antioxidant activities were determined by in 1,1-diphenyl-2-picryl-hydrazil (DPPH) free radical scavenging activity test and reducing power assay. The essential oil fraction of A. sylvestris revealed significant inhibiting activities against antibiotic-susceptible and -resistant species of Vibrio and Shigella with MICs ranged from 1.00~4.00 mg/ml. It showed synergistic or additive effects when it was combined with amphicillin or trimethoprim/sulfamethoxazole (1 : 9). Additionally, the essential oil fraction of A. sylvestris exhibited significant DPPH free radical scavenging activity and the reducing power.

  • The essential oils from Cedrus atlantica, Styrax tonkinensis, Juniperus communis, Lavandula angustifolia, Melaleuca alternifolia, Pelargonium graveolens, Pogestemon patchouli and Rosmarinus officinalis were analyzed by GC-MS. Antifungal activities of the oils were investigated by disk diffusion assay and the broth dilution method against Aspergillus niger and A. flavus. The effects of geraniol and the essential oil fraction from P. graveolens on the antifungal activity of amphotericin Band ketoconazole were examined using a checkerboard microtiter assay against both Aspergillus fungi. Most of the tested essential oils, with the exception of C. atlantica, J. communis, and P. patchouli, significantly inhibited growth of A. niger and to a lesser extent that of A. fIavus, with MICs (minimal inhibitory concentrations) in the range 0.78-12.5 mg/mL. The essential oil fraction of P. graveolens and its main components, geraniol and citronellol, exhibited additive effects with amphotericin B and with ketoconazole against both Aspergillus species, resulting in fractional inhibitory concentration (FIC) indices ranging from 0.52 to 1.00.

  • Essential oils extracted from Chamaecyparis obtusa were applied to make antibacterial corrugating liner. The quantitative analysis of the essential oils was carried out by GC-MS, which showed that the monoterpenes as a basic component of the essential oils extracted from Chamaecyparis obtusa in the domestic mountain were greater in amount than those in China. The antibacterial activity was then examined with Tyromyces palustris and gram-negative/positive bacteria. The papers treated with the essential oils desplayed great resistance against T. Palustris and gram bacteria but the best results were obtained with the handsheet formed by softwood bleached kraft pulp rather than the liner by OCC. The low antibacterial activity of the liner was considered to be due to starch components which could be readily attacked by the fungi.

  • The effect of the essential oil obtained from Chrysanthemum boreale Makino on the apoptosis of KB cells was investigated. Cytotoxicity and cellular DNA content were analyzed by MTT assay, flow cytometry, agarose gel electrophoresis, and Hoechst 33258 staining. The caspase-3 and poly (ADP-ribose) polymerase (PARP) proteins were estimated by Western blotting method. The various cytotoxic effects of the essential oil which are hallmarks of apoptosis, including DNA fragmentation, apoptotic body formation, and sub-G1 DNA content, all progressed in a dose-dependent manner. Treatment with an apoptosis-inducing concentration of the essential oil caused rapid and transient induction of caspase 3 activity. Further, the efficacious induction of PARP cleavage and caspase-3 activation was observed at an essential oil concentration of 0.1 and 0.2 mg/mL for 12 hr.
