Essential oils and aromatherapy have traditionally been used for the treatment of anxiety and depression with few side effects. This study aimed to investigate the effects of essential oils from six herbal prescriptions known to be effective in treating anxiety and depression in Korean medicine. The neuroprotective and anti-neuroinflammatory effects of six essential oils, including Gamisachil-tang (GMSCT), Guibi-tang (GBT), Sihogayonggolmoryeo-tang (SYM), Danchisoyosan (DCSYS), Sihosogansan (SHSGS), and Soyosan (SYS), were examined in PC12 and BV2 cells. In corticosterone (CORT)-stimulated PC12 cells, all six essential oils ameliorated the CORT-induced decrease in cell viability at a concentration of 10 ㎍/ml. GMSCT, GBT, and SHSGS recovered CORT-induced cytotoxicity at concentrations of 1 ㎍/ml and 10 ㎍/ml. In lipopolysaccharide (LPS)-stimulated BV2 cells, GBT (10 ㎍/ml) decreased interleukin (IL)-1β production, whereas SHSGS (1 ㎍/ml) inhibited tumor necrosis factor (TNF)-α production. In the MK-801-induced anxiety in zebrafish, electroencephalogram (EEG) assessment indicated that GMSCT and SHSGS induced recovery in the delta and beta power densities and reduced theta/beta and delta/beta ratios. DCSYS and SYS decreased theta power density and theta/beta ratio, whereas GBT and SYM showed no effects on EEG signals. In the tail suspension test (TST) in mice, GBT, DCSYS, SHSGS, and SYS exhibited antidepressant-like effects by decreasing immobility time. These results suggest that the essential oils from the six herbal prescriptions, except SYM, may have beneficial effects on anxiety and/or depression. Further studies should be conducted to investigate the molecular signaling pathways that mediate the effects of these essential oils on anxiety and depression.

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.

본 연구는 식물에서 항생제로 알려진 11 가지 에센셜 오일(피톤치드)을 선별 한 후 혼합한 정유를 사용하여 최고의 항생제를 조사하였다. 최소억제농도 (MIC)와 최소사멸농도 (MBC) 측정 결과 Essential Oil B와 E가 목적 균의 억제효과가 높았다. 이 실험에 사용 된 S. aureus를 함유하는 모든 그람 양성 박테리아는 높은 항생제 활성을 나타냈다. 그리고 그람 양성 박테리아에서 A. baumanii와 곰팡이에서 C. albicans만이 높은 항생제 활동을 보였다. 우리의 실험에 사용 된 에센셜 오일은 항생제 활성이 뛰어난 천연 항생제 및 자연 의학의 에센셜 오일을 사용한 주요 연구와 비교할 때 더 우수한 항생제 활성을 보였다. 시험에 사용한 공시물질인 Essential Oil이 어떤 항균활성의 기전을 가지는지 알 수 없으나 다른 선행 연구결과와 비교해 볼 때 세포벽의 합성저해기전으로 해석하고 있다. 이러한 결과로부터, 항생제 활성을 갖는 일부 물질 또는 기능성 제품이 개발 될 것으로 예상된다.

Effect of the plant essential oils on the growth of Malassezia pachydermatis was evaluated and the essential oils of Ocimum basilicum L., Melaleuca alternifolia (Maid. & Bet.) Cheel, and Rosa damascene Mill. were the most active against M. pachydermatis and their activity were high than that of itraconazole at 2 mg/mL. The major constituents of the three oils by GC-MS analysis were linalool (21.83%) and estragole (74.29%) for O. basilicum, a-terpinolene (17.96%) and terpinen-4-01 (45.54%) for M. alternifolia, and a-citronellol (59.98%) and geraniol (27.58%) for R. damascene. Results showed that these selected three oils could be effective toward controlling M. pachydermatis opportunistic infections.

Mutagenic acivity of essential oils was tested using Salmonella typhimurium TA100 in the presence or absence of 59 fraction prepared from the mouse liver. Growth inhibitory effect of the oils on the bacteria was measured to warrant the mutagenic effect. Most oils were (round to be very strongly toxic against the bacteria at a high dose $(2,000{\mu}g/plate)$. At lower doses than this concentration, the Curcuma longa oil was found to be the most mutagenic with S9 fraction whereas it was not mutagenic without the fraction suggesting that this oil could undergo activation for the mutagenicity by cytochrome P45O. However, the mutagenicity of the Eugenia caryohpylata oil was disappeared under S9 fraction. Other oils obtained from Cinnamomum cassia, Chrysanthemum sibiricum, Paeonia moutan the flower of Artemisia princeps var. Orientalis, Allium sativum, were not mutagenic. This result suggested that antimutagenicity assay on the essential oil is necessary for the biological available substances.

Citrus essential oil (bergamot, grapefruit, lemon, mandarin, petigrain)이 B16 melanoma 세포에서 melanin 생성에 미치는 영향과 RBL 2H3 비만세포에서 ROS 생성에 미치는 영향을 관찰하였다 5 종류의 citrus essential oil은 DPPH 라디칼 소거와 세포 증식 및 독성에서 대조군에 비해 유의한 변화를 일으키질 않았다. 정제한 tyrosinase 활성에 있어서 mandarin과 petigrain essential oil은 유의하게 tyrosinase 활성을 억제하였으나 bergamot은 전혀 억제하지 않았다. 이러한 결과는 mandarin과 petigrain essential oil이 tyrosinase 효소 억제 기전은 설명하지 못하지만 tyrosinase 효소에 직접적으로 작용하여 억제하는 것으로 보인다. B16 melanoma 세포에서 MSH에 의한 melanin 생성이 5 종류의 citrus essential oil에 의해 모두 농도 의존적으로 억제되었다. Bergamot essential oil은 tyrosinase 효소 활성을 직접적으로 억제하지는 못했지만 melanoma 세포에서 MSH에 의한 melanin 생성은 억제하는 것으로 나타났다. 다른 4종류의 citrus essential oil도 모두 tyrosinase 효소 활성을 억제하였으며, MSH에 의한 melanin 생성도 억제하였다. 한편 DCF-DA를 이용한 ROS 생성에 있어서는 madarin essential oil은 ROS 생성에 이렇다 할 영향을 주지 않았지만 다른 4개의 essential oil (Bergamot, Grapefruit, Lemon, Petigrain)은 농도 의존적으로 ROS 생성을 증가시켰다. 이상의 결과를 종합하여 볼 때 citrus essential oil은 MSH에 의한 melanin 생성을 억제하는 것으로 보아 미백제로서의 개발 가능성이 있는 것으로 사료된다.

In continuation of our studies on essential oils of Angelica genus(Umbelliferae), We report on the components of essential oils obtained from the root of Angelica tenuissima Nakai(藁子). Oils were obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. Essential oils of the root of A. tenuissima(Gaoben) were found to contain $\alpha-pinene,\;camphene,\;\beta-pinene,\;myrcene,\;\alpha-phellandrene,\;\Delta-3-carene,\;p-cymene,\;limonene,\;\gamma-terpinene,\;terpinolene,\;4-vinylguauacol,\;\gamma-elemene$, one aromatic compound, three unidentified sesquiterpene alcohols, butylidenephthalide, senkyunolide and Z-ligustilide which was the most abundant compound comprising 75% of the whole oil. Also butylphthalide and hydroxybutylidenephalide were tentatively identified.

The influence of essential oils from aboriginal softwoods as Pinus densiflora, Pinus koraiensis, Chamaecyparis obtusa and Chamaecyparis pisifera on the motor coordination, pulse, mean blood artery pressure and pain reducing test was investigated in mice and rats. The motor coordination of mouse was not induced by the inhalation of each oil. Furthermore, these oils did not alter the changes of the mean blood pressure and pulse rate. Chamaecyparis pisifera trand to reduce the mean blood pressure. The abdominal pain induced by acetic acid was reduced only by an essential oil from Pinus koraiensis in mouse.

Objective : The content of essential oils from Ssajuari and Sajabalssuk was analyzed based on storage period. A total of eight samples old Ssajuari (harvested in 2000, 2001, 2002, 2003, and 2004), fresh Ssajuari (harvested in 2004), old Sajabalssuk (harvested in 2002), and fresh Sajabalssuk (harvested in 2004) was analyzed. Methods : The analysis of the content of essential oils from Ssajuari and Sajabalssuk was conducted by GC/MS. Results : The main essential oils of Ssajuari were ${\beta}$-thujone and 1.8-cineole. The ${\alpha},{\beta}$-thujone and 1,8-cineole were increased but the caryophyllene oxide was decreased. in accordance with storage period. The main essential oils of fresh Sajabalssuk were trans-${\beta}$-caryophyllene, terpinen-4-ol. The main essential oils of old Sajabalssuk was ${\beta}$-thujone and 1,8-cineole like Ssajuari. But 1,8-cineole was higher than that of Ssajuari samlpes. Conclusion : All samples had trans-sabinene hydrate, 1,8-cineole, terpinen-4-ol and caryophyllene oxide. According to stored year, ${\beta}$-thujone, ${\alpha}$-thujone were increased but terpinen-4-ol, caryophyllene oxide were decreased.
