The summary of a study of efficacy of Rose essential oil and Lavender essential oil against skin-inflammation caused to surfactant is as follows. As a result of protein analysis, although Rose essential oil and Lavender essential oil stimulates skin, there is no much alteration of protein. The alteration of protein's bend to be under part of 43Kd is appeared in the group treated Rose essential oil and Lavender essential oil. The stratum of the group treated by surfactant is more, the stratum of the group treated by surfactant is more thick. As the observed result of alteration of basal layer, it is seen that the group treated Rose essential oil and Lavender essential oil takes the shape of cell layer constant, and the group treated Rose essential oil is made the basal cell layer of normal structure than that of Lavender essential oil. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}20$), (${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number, and Mast cell's size is larger than the damaged group.

The summary of a study of efficacy of Rose essential oil and Lavender essential oil against physiologic active change s of skin caused to surfactant is as follows. 1. In feed intake efficiency, there is more significant difference than control group, and then in water intake, there are significant differences between each group. It is presented that the water intake efficiency ratio of the group treated by Rose essential oil and Lavender essential oil is higher than all of groups to be participated in experiment. And then, the reason that the group treated Lavender essential oil is lower than any other group is needed water intake to be caused by stress. 2. As the result of serum analysis, in atherosclerotic index(A.I), the cholesterol of control group is higher than that of the group treated. As HDL cholesterol is activated, the dan1aged group is higher than control group, in LDL cholesterol the control group is higher. It is seen that the damaged group of the quantity of HDL cholesterol is lower frequently in A.I. This fact is presented that HDL cholesterol that cholesterol is exhausted is changed, because of the dan1aged group that replacement is activated. 3. As the observed result of alteration of sebaceous glands, it is appeared that the demage of sebaceous glands is destroyed in the damaged group. It is observed that epidermis of the group applied by Rose essential oil after treated surfactant is dry, secretion of phenomenon of water and sebum is appeared more. It is observed that the epidermis recovery of the group applied by Lavender essential oil after treated surfactant is insufficient. And then it is seen that stratum corneum is recovered and the quantity of sebum secretion is decreased. 4. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number and Mast cell's size is larger than the dan1aged group. It is presented that the Mast cell's number and Mast cell's size is larger than the damaged group, the Mast cell's size and quantity of the group treated by Rose essential oil and Lavender essential oil is decreased more.

Analysis of the aroma constituents present in the rose essential oil of Chinese Kushui type (Rosa sertata ${\times}$ Rosa rugosa) by GC-FID and GC-MS was performed independently as an expert for the inter-laboratory round-robin test to verify reproducibility according to the decision of the preliminary meeting of ISO/TC-54 (Shanghai, Sep. 14-15, 2010). Total 179 peaks (using SPB-1 apolar column), 165 peaks (using DB-624 intermediate polar column), and 162 peaks (using Supelcowax-10 polar column) were separated by GC-FID, respectively. Major constituents (over 5%) by GC-FID were ${\beta}$-citronellol (41.6~46.7%), geraniol (9.7~11.0%), and nerol (3.4~4.5%). ${\beta}$-Citronellol peak was overlapped with nerol peak on SPB-1 and DB-624 columns, whereas the two peaks were separated each other on Supelcowax-10 column. Our results were generally consistent with Chinese data (ISO/DIS 25175); however, a peak of phenethyl alcohol separated by using PEG (Supelco wax) column was found at the quite different retention time. Comparative analysis was conducted using Bulgarian rose (Rosa damascena Miller) oil and perfume. Bulgarian rose oil showed rich amounts of characteristic aroma constituents than the essential oil of Chinese Kushui type.

The number of natural products obtained from plants has now reached over 100,000 and new chemical compounds are being discovered ever year. Medicinal and Aromatic plants and their extracts have been used for centuries to relieve pain, aid healing, kill bacteria and insects are important as the antifungal and anti-herbivore agents with further compounds being involved in the symbiotic associations. Although their functions in plants have not been fully established, it is Known that some substances have growth regulatory properties while others are involved in pollination and seed dispersal. The complex nature of these chemicals are usually produced in various types of secretory structures which is an important character of a plant family and also influenced and controlled by genetic and ecological factors. Detailed anatomical description of these structures ave relevant to the market value of the plants, the verification of authenticity of a given species and for the detection of substitution or adulteration. Volatile oils are used for their therapeutic action for flavoring of lemon, in perfumery of rose or as starting materials for the synthesis of other compounds of turpentine. For therapeutic purposes they are administered as inhalations of eucalyptus oil, peppermint oil, as gargles and mouthwashes of thymol and transdermally many essential oils including those of lavender, etc. With these current trend for using volatile components in essential oil will be increasing in the future in Korea and in the world as well.

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.

The purpose of this study was to verify the effect of aromatherapy on the stress response in menstrual period. Method: A randomized, single-blind, pretest- posttest design was used. The study subjects were 60 college women with dysmenorrhea and they were randomized into 3 groups, experimental, 1st control(placebo) and 2nd control group. The researchers massaged treatment oil(3% dilution essential oil of Lavender, Clary sage and Rose) into the abdomen of experimental group. The placebo group used almond oil(carrier oil) instead, and the 2nd control group did not give any treatment. Baseline data including pre-treatment stress response score were obtained on the first day of usual period. Aromatherapy provided for about 7 days until the next cycle began. Post-treatment stress responses were measured by 94 item SOS(symptom of stress) scale on the first day of the cycle. Results: As a results, the stress response score of experimental group was significantly lower than two control groups. And there was no significant difference in stress responses of two control groups. Conclusion: The results show aromatherapy using selected essential oils to be an effective intervention for stress response during menstruation.

The present study aimed to evaluate the phytotoxic potential of essential oils. For this purpose, 18 essential oil samples extracted from Korean plants and 64 commercial essential oils were screened for their phytotoxic potential against the seedling growth of Brassica napus L. (rapeseed). Among the 82 samples, 11 commercial oils (cinnamon, citronella, clove, cumin seed, geranium, jasmine, lemongrass, palmarosa, pimento, rose otto and spearmint) strongly inhibited the seedling growth with $GR_{50}$ value < $150{\mu}g\;mL^{-1}$. Major components from these effective essential oils were identified by solid phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS). GC-MS analyses revealed that the effective samples mainly consist of benzyl benzoate, carvone, citral, citronellol, eugenol, geraniol, D-limonene and terpinene. Subsequently, bioactivity of these individual components was evaluated against the seedling growth of B. napus, Echinochloa crus-galli and Aeschynomene indica. The components from different chemical groups exhibited different potency in inhibiting the seedling growth with varied $GR_{50}$ values ranged from $29{\mu}g\;mL^{-1}$ to > $1000{\mu}g\;mL^{-1}$. In the greenhouse experiment, citral and geraniol completely suppressed the growth of all the tested 10 plants at $100kg\;ha^{-1}$. In conclusion, the individual essential oil components geraniol and citral could be used as natural herbicides for weed management.
