The cosmetic and toiletries are necessary health care & household for common life. However we need antiseptic which is effecting harmlessly to the human body. There are propolis, Lavender, Lemon, essential oil in the natural antiseptic materials. This work proceeded design Natural-antiseptic system with three materials as above-mentioned. Natural-antiseptic system was accomplished with propolis (2%), Lavender essential oil (0.3%), Lemon essential oil (0.3%) safety out of Polysorbate 20 (0.5%), Polysorbate 80 (0.5%), PEG (60) hydrogenated castor oil (0.45%), ethanol (5%). The antimicrobial test was experimented on E. coli and Bacillus stearothermophilus. In this antimicrobial test, we found that the effect of antisepsis against E. coli and Bacillus stearothermophilus with propolis 0.3%, Lavender essential oil 0.045% and Lemon essential oil 0.045% was improved. Therefore could expect Natural-antiseptic system product for moisturizing skin toner for face, nourishing essence and wet tissue for clean other things.

Compositional changes In essential oil of Zanthoxylum piperitum A.P. DC. were investigated under six different storage conditions for 3 months. Essential oil from Zanthoxylum piperitum was collected by steam distillation method and analyzed by gas chromatography-mass selective detector (GC-MSD). Forty-one volatile compounds, consisting of 12 hydrocarbons, 11 alcohols, 8 aldehydes, 3 oxides, 3 esters, 3 ketones and 1 acid were identified from the fresh essential oil of Zanthoxylum piperitum. In essential oils, compositional changes occurred in particularly monoterpene hydrocarbons. Total levels of ketones, esters, oxides and alcohols increased during storage. Moreover, aerobic condition caused decrease in a few constituents duringstorage even at low temperature.

Increasing public concerns over odors and air regulations in nonattainment zones necessitate the remediation of a wide range of odorous compounds used for industrial purpose. Currently, spraying technique using neutralizing essential oils is utilized to treat ammonia odors. The chemical analysis was performed to analyze the composition of an essential oil by GC-MS. The monoterpenes in an essential oil react with ammonia by neutralization and their reaction mechanism was elucidated. However, little information is available on the neutralization reaction with rendering air pollutants in detail. The objective of this study was to clarify the possibility of the neutralization of odors sprayed in indoor and determine the removal efficiencies in the misty aerosol by different input odor concentration. It was found that an ammonia was significantly removed by the spraying technique, and the removal efficiency of ammonia was 98 %. The removal efficiencies of ammonia were also studied by the optimal conditions such as temperature and pH.

본 실험은 수경재배시 마죠람과 오레가노의 알맞은 배양액 농도를 구명하기 위하여 실시했다. 배양액은 유럽채소연구센터 허브액을 사용했다. 처리농도는 0.5, 1.0, 2.0, 3.0배액 등 4수준이었고 재배기간은 40일이었다. 마죠람은 지상부 생육, 지하부 생육, 비타민 C,총 정유생산량은 0.5배액에서 가정 조았다. 그러나 무기물함량은 20.배액에서, 정유함량은 3배액에서 좋았으며 엽록소 함량은 고농도에서 감소하였다. 오래가노의 생육 0.5배야ㅐㄱ에서 조았으며, 3.0배액에서는 고사하였다. 엽록소 함량은 2.0배액에서 낮았으나 비타민 C는 이온농도에 영향을 받지 않았다. 무기물과 정유함량은 1.0배액에서 높았으나, 정유생산량은 0.5배액에서 높았다. 이사의 결과로 볼 때 마죠람과 오레가노 수경재배시 적절한 배양액 농도는 허브 배야액 0.5배인 것으로 생각된다.

1. 무좀균에 대한 각 시료들이 항균력으로는 terbinafine > 100%-bamboo oil > 50%-bamboo oil 순으로 나타내었다. 무좀균에 대한 Bamboo oil에 대한 영향으로는 T. M > E.F > T.R의 순서대로 항균력을 나타내었으며, 특히 T.M에 대하여 가장 우수하게 나타내었다. 2. 비듬균에 대한 각 시료들이 항균력으로는 terbinafine > 100%-bamboo oil > 50%-bamboo oil 순으로 나타내었다. 비듬균에 대한 Bamboo oil에 대한 영향으로는 P.O-75 > P.O-77의 순서대로 항균력을 나타내었으며, 특히 P.O-75에 대하여 가장 우수 하게 나타내었다. 3. 50%-bamboo oil은 무좀균과 비듬균에 대하여 항균력이 있는 것으로 나타내었으며, 100%-Bamboo oil의 항균력과 비슷하게 나타내었으며, 경비 절감 측면에서 기대를 걸 수 있을 것으로 사료된다.

Quality stability of the herb pill coated with edible oils containing rosemary was investigated. Herb pills were made of herb powders such as Panax ginseng, Cinnamomum cassia, Lycium chinense, Zyzyphus jujuba and Zingiber officinale. Rapeseed oil and lubriol were used as edible coating oil. After herb pills coated with edible oils with or without rosemary were stored at 40℃ for 180 days, the microbial viable cell counts and peroxide values(POV) of the herb pill were investigated. After 180 day storage, POVs of herb pills with only rapeseed oil or lubriol were 0.51 and 0.49 meq/kg, respectively. However, when rosemary was added in herb pills the POVs were decreased to 0.30 and 0.39 meq/kg, respectively. The addition of rosemary to the rapeseed oil and lubriol tended to decrease the microbial viable cell counts of the herb pill. The microbial viable cell counts of rapeseed oil and lubriol were 940 and 820CFU/g, respectively after 180 days of storage. However, these levels were suppressed to 720 and 640CFU/g by the resemary addition. On the other hand, the ginseng saponin content of herb pills was not affected by the rosemary addition during storage.

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-1로 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 α-citral로 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.

In order to develop a antimicrobial agent, dried bamboo trunk was extracted by high temperature suction and then antimicrobial activities against Staphylococcus aureus ATCC 2825 and Escherichia coli DH 5α were investigated as compared with tea tree oil and BHA. The minimal inhibitory concentration(MIC) of the extracted substance against microorganisms were also examined. The results are as follows: 1. By disc diffusion method, BHA showed the strongest antimicrobial activity on Gram-positive bacteria such as S. aureus ATCC 2825 but bamboo essential oil showed the strongest antimicrobial activity on Gram-negative bacteria such as E. coli DH 5α. 2. By broth dilution method, the minimum inhibitory concentration of the BHA, tea tree oil and bamboo oil were not detected against S. aureus ATCC 2825(MIC, 6.0 ㎕/㎖) and E. cola DH 5α(MIC, 6.0 ㎕/㎖)

본 실험은 고기능성 채소 생산을 위한 배양액내의 적정 셀레니움 농도를 구명하고자 수행되었다. 벨기에의 채소연구소에서 허브재배를 위해 개발된 양액을 이용하여 각각 Na2SeO4를 0, 2, 4, 6, 8mg/l농도로 처리하였다. 배양액내 셀레니움의 농도가 국화과 식물인 향쑥의 생육에 미치는 영향을 알아본 결과 저농도의 처리는 생육을 향상시켰으나 6mg/l이상의 고농도 처리는 생육을 감소시켰다. 엽록소의 함량은 셀레니움 처리에 의해 증가되었는데 배양액 내의 selenate ion 농도가 높을수록 전체 엽록소함량도 증가되었다. 비타민 C의 함량은 좋은 생장을 보였던 4mg/l처리까지는 증가하였으나 그 이상으로 농도가 증가했을 때 비타민C의 함량은 감소하였다. 저농도의 selenate 이온 농도는 정유의 함량을 증가시켰으나 고농도에서는 정유의 함량이 감소되었다. 식물에 의한 셀레니움의 흡수는 배양액내의 selenate 이온 농도가 증가할수록 촉진되었다.
