  • Efficiency study of chamomile and Thyme essential oil about the basal layer & sebaceous gland in dry-skin induced by surfactant is as following : 1. Formal observation of outer skin layer and basal layer There was refreshing effects about Surfactant induction skin inflammation in Chamomile, Thyme essential oil processing group but effect in surface layer appeared by higher thing in Chamomile essential oil and it could know that thing which do not use Thyme essential oil in case Thyme essential oil is ultraviolet rays allergy at skin care because Melanocyte appear on the surface is bigger than Chamomile essential oil that it was usefully reaction in basal layer. 2. Formal observation result of sebaceous glands. There are few damages in all group but there is recuperative through excessive water damage by excessive a sebaceous gland made of mulberry bark secretion because Thyme essential oil application group cause chapped skin phenomenon after surface-active agent processing but is seen that difference does not exist greatly and Thyme essential oil that general skin is strong in permeation is effective, but Surfactant induction skin inflammation estimates that Chamomile essential oil is effective. Therefore, it was considered that use of Chamomile essential oil is effectiveness than Thyme essential oil by essential oil used for recovery after damage of inflammation etc..

  • Antimicrobial coating on chicken carcasses may reduce the effects of cross-contamination and improve product shelf-life and safety. Thyme oil was mixed at 0.5%(v/v) with a pre-gelatinized pea starch coating solution. The coating solution was spread on chicken breast meat after inoculation with selected spoilage and pathogenic bacteria. After inoculation, the chicken meats were packaged in plastic bags and stored at $4^{\circ}C$. During 12 day storage, total aerobic bacteria, lactic acid bacteria, and inoculated organisms were counted at 4 day intervals. Thyme oil treatments reduced the viability of Salmonella as well as the growth of Listeria and Pseudomonas by 2 log CFU/g, and appeared to eliminate inoculated Campylobacter during storage. The addition of thyme oil increased the viscosity of the pre-gelatinized pea starch solution. The results suggested that thyme oil inclusion in an edible starch coating may be a satisfactory delivery system to enhance the safety of processed fresh meat.

  • Thymus속의 common thyme과 thyme의 담액수경 재배시 배양액의 이온농도를 달리하여 두 종의 생육과 품질을 비교하였다. 배양액의 이온농도는 1.2, 2.4, 4.8 그리고 $7.2mS.cm^{-1}$로 하였다. 두 종 모두 $0.5(EC=1.2\;mS.cm^{-1})$배와 1배의 낮은 이온농도 처리에서 생육이 좋았다. Common thyme과 lemon thyme의 생육은 배양액내 이온농도가 높아질수록 건물율은 증가했으나 초장, 근장과 생체중은 감소하였다. 엽록소 함량은 lemon thyme에서 더 높았으나 비타민 C의 함량과 정유함량은 common thyme에서 더 높았다. 두 종간의 주요 정유 성분 차이를 보면, common thyme의 주성분은 thymo과 carvacrol이고, lemon thyme은 geranio과 ${\alpha}-citral$로 각각 정유 성분의 50~70%를 차지하고 있다. 이들의 각 주성분의 함량은 생육이 좋았던 0.5배에서 가장 많았다. 결과적으로 수경재배시 common thyme과 lemon thyme 모두 허브 배양액 0.5배액으로 재배시 우수한 품질의 작물을 생산할 수 있었다.

  • The objective of this study was to determine inhibitory activities of four volatile plant essential oils (cinnamon oil, fennel oil, origanum oil and thyme oil) on in vitro growth of Fusarium oxysporum f. sp. fragariae causing Fusarium wilt of strawberry plants. Results showed that these essential oils inhibited in vitro conidial germination and mycelial growth of F. oxysporum f. sp. fragariae in a dose-dependent manner. Cinnamon oil was found to be most effective one in suppressing conidial germination while fennel oil, origanum oil and thyme oil showed moderate inhibition of conidial germination at similar levels. Cinnamon oil, origanum oil and thyme oil showed moderate antifungal activities against mycelial growth at similar levels while fennel oil had relatively lower antifungal activity against mycelial growth. Antifungal effects of these four plant essential oils in different combinations on in vitro fungal growth were also evaluated. These essential oils demonstrated synergistic antifungal activities against conidial germination and mycelial growth of F. oxysporum f. sp. fragariae in vitro. Simultaneous application of origanum oil and thyme oil enhanced their antimicrobial activities against conidial germination and fungal mycelial growth. These results underpin that volatile plant essential oils could be used in eco-friendly integrated disease management of Fusarium wilt in strawberry fields.

  • Purpose: The purpose of this study was to evaluate the effects of essential oil on oxidative stress, immunity, and skin condition in atopic dermatitis (AD) induced mice. Methods: This study was a $3{\times}3$ factorial design. Factors were oil type (Lavender, Thyme, and 2:1 mixture of lavender and thyme oil [blending oil]) and treatment period (0 day, 7 days, and 21 days). The samples were 45 mice with AD and randomly assigned to nine groups of five mice per group. The dependent variables such as superoxide radical, IgE, degranulated mast cells, and epidermal thickness were measured. Data were collected from February to April in 2014. Descriptive statistics, One-way ANOVA, Two-way ANOVA, and Tukey's HSD test were performed using the SPSS WIN 20.0 program. Results: Dependent variables were not statistically significantly different by the three oil types (p >.05). Essential oils such as lavender, thyme, and blending oil were all effective in reducing AD symptoms and especially 2:1 blending oil were most effective. There were statistically significant differences by the three treatment periods in all dependent variables (p <.001). There were statistically significant interactions between oil types and treatment periods in all dependent variables (p <.01). For decreasing superoxide radical, degranulated mast cells, and epidermal thickness, 2:1 mixed oil should be applied for at least 21 days. Otherwise to reduce IgE, 2:1 mixed oil should be used for at least 7 days. Conclusion: These findings provide bases for developing effective interventions for AD patients to manage their AD symptoms.

  • Repellencies of herb plants and essential oils against alate Myzus persicae were investigated in a insect cage, a screen house, and a tobacco field. Numbers of nymphs deposited by alate or apterous Myzur persicae were lower on rosemary(Rosmarinus officinalis), silver thyme (Thymus vulgaris), and lemon balm(Melissa of fcianazis). Rosemary and silver thyme show little repellency against alate Myzus persicae on a nearby tobacco plant Rosemary oil, peppermint (Mentha piperita) oil, and ginger oil showed repellency against alate Myzus persicae, but spearmint (Mentha spicata) oil and lavender oil showed little repellency in a screen house. Rosemary oil, ginger oil, peppermint oil, lavender oil, and spearmint oil showed repellency against alate Myzus persicae in a tobacco field, but there was no significant difference among oils.

  • Vapours from origanum oil (O) and thyme oil (T) were applied to the four soil-borne strawberry pathogens Fusarium oxysporum f. sp. fragariae, Colletotrichum fructicola, Lasiodiplodia theobromae, and Phytophthora cactorum, causing Fusarium wilt, anthracnose, dieback, and Phytophthora rot, respectively. Increasing T vapour doses in the presence of O vapour strongly inhibited mycelial growths of the four pathogens and vice versa. When mycelia of F. oxysporum f. sp. fragariae and P. cactorum exposed to the combined O + T vapours were transferred to the fresh media, mycelial growth was restored, indicating fungistasis by vapours. However, the mycelial growth of C. fructicola and L. theobromae exposed to the combined O + T vapours have been slightly retarded in the fresh media. Prolonged exposure of strawberry pathogens to O + T vapours in soil environments may be suggested as an alternative method for eco-friendly disease management.
