Myristica fragrans Houtt is commonly known as "nutmeg", it produces two spices: mace and nutmeg. Mace and nutmeg are strongly aromatic in nature and known as jowzabuwa and javetri/bisbasah respectively in the Unani system of medicine. M. fragrans was used as early as 700 BCE by Indian, however, ancient Greeks and Romans were not aware of it. Later Arab traders introduce M. fragrans into Europe followed by Portuguese and Dutch merchants. Mace is very useful medicine in the Unani system of medicine because of its therapeutic uses in salasal al-bawl (urinary incontinence), amrad-i-qalb (cardiac diseases), amrad-i-dimagh (central nervous system), zo'fe bah (sexual debility), amrad al-rahim (uterine diseases), and su-i-hazim (indigestion). The most important constituents of mace essential oil are ${\alpha}-pinene$, sabinene, myrcene, limonene, 1,8-cineole, terpinen-4-ol, myristicin, ${\gamma}-terpinene$, and safrole. The seed and mace extract of nutmeg contain quite high tannins, flavonoids, and terpenoids. Mace has pharmacological functions such as antibacterial and antifungal, anti-inflammatory, analgesic, antidiarrhea, antioxidant, chemoprotective, neuropharmacologic, and antidiabetic properties. To explore the correlation between the traditional uses and the same proven by recent researches, a comprehensive review is highlighted in this paper. Further, pharmacological activities which are not reported in classical texts are also discussed.

Seasonal variations in the profile and concentrations of essential oil in Zanthoxylum piperitum were investigated by gas chromatography-mass spectrometry. Seasonal changes in the percentages of the main constituents of the essential oil of both leaves and fruits from Z. piperitum varied. Variations in essential oil yield and the amount of monoterpenes and sesquiterpenes in leaves and fruits at different developmental stages were significant. The characteristic content of essential oil in leaves was determined mainly due to the content of monoterpenes, and that in fruits was determined largely due to the sesquiterpenes. Twenty-nine compounds in the oil from Z. piperitum leaves were detected; the major compounds were ${\beta}$-phellandrene (26.90%), citronella (15.32%), ${\beta}$-myrcene (3.24%), ${\alpha}$-pinene (2.79%), trans-caryophyllene (2.66%), and fanesyl acetate (2.30%). The highest yield of oil (43.89%) in Z. piperitum leaves was obtained in May but decreased gradually beginning in June. The yield of essential oil from Z. piperitum leaves during early periods was higher than that during later periods and usually decreased from early maturation stages to subsequent stages. However, in contrast to leaves, the oil yield in Z. piperitum fruit increased in June, and oil yield later in the season was higher than that earlier in the season. These results indicate that the essential oil produced from Z. piperitum leaves at the early developmental stages was stored in leaves, and might be transferred to fruit at the final developmental stages.

Berries and branches essential oil of Juniperus phoenicea were obtained by electromagnetic induction heating assisted extraction and by hydrodistillation with a yield varied from ($1.2{\pm}0.3$ to $2.4{\pm}0.7%$) and from ($0.6{\pm}0.1%$ to $1.1{\pm}0.1%$), respectively. forty eight compounds were identified representing (97.2 - 99.7%) of the oil. ${\alpha}$-Pinene (40.3 - 67.8%) and ${\delta}$-3-carene (13.5 - 26.8%) were the main compounds in berries and branches essential oils. Antioxidant activity was evaluated by three means: inhibition of 2, 2-diphenyl-1-picryl hydrazyl (DPPH) free radical, reducing power and ${\beta}$-Carotene/linoleic acid bleaching. The antioxidant activity of essential oils showed $IC_{50}$ ranging from $67.6{\pm}1.02{\mu}g/mL$ to $131.5{\pm}0.8{\mu}g/mL$ for berries and from $98{\pm}1.25{\mu}g/mL$ to $166.8{\pm}0.29{\mu}g/mL$ for the branches. Berries oil show more potent antioxidant activity compared to branches. This result is supported by the three methods investigated in this work.

The effects of gamma ray or electron beam irradiation on herbaceous medicinal plants were investigated in terms of the composition of volatile constituents using the aerial parts or leaves of Artemisia princeps Pamp. cv. Ganghwayakssuk and Artemisia argyi cvs. Namhaeyakssuk and Hwanghaessuk. The composition of volatile constituents in leaves was clearly distinguishable among the three Artemisia cultivars. However, the relative proportions of the major volatile constituents such as 1,8-cineole, ${\alpha}$-pinene, camphene, santolina triene, and artemesia triene, were similarly changed in two or three cultivars by gamma ray or electron beam irradiation. In particular, the proportion of 1,8-cineole was increased up to 1.29- to 1.71-fold in the three cultivars after irradiation with gamma ray. These results suggest that gamma ray or electron beam irradiation can be applied to modulate the composition of volatile constituents in the leaves of Artemisia plants.

To fulfill the increasing demand for a high quality of flower, we investigated the effects of nitrogen application on plant growth, yield and bioactive compounds of Chrysanthemum indicum L.. C. indicum L. was cultivated in a pot scale, and nitrogen applied with the level of 0 (N0), 50 (N50), 100 (N100), 150 (N150), 200 (N200) and $300\;(N300)\;kg\;ha^{-1}$ to suggest optimum rate of nitrogen fertilization. Phosphate and potassium applied the same amount of $80-80\;kg\;ha^{-1}$ ($P_2O_5-K_2O$) in all treatments. Growth characteristics and yields of C. indicum L. were significantly affected by nitrogen application. Maximum yield achieved in 265 and $295\;kg\;ha^{-1}$ N treatment on the whole plant and the flower parts, respectively. The nitrogen content and uptake of whole plant significantly increased by the increase of nitrogen application. Five major components of essential oil, $\alpha$-pinene, 1,8-cineol, chrysanthenone, germacrene-D, and $\alpha$-curcumene in flowerheads of C. indicum L. occupied approximately 40% of peak area, germacrene-D decreased by the increase of nitrogen application among them. However, cumambrin A contents in the flower parts of C. indicum L. were affected negatively by the increase of nitrogen application, but total yields of cumambrin A in flower part significantly increased. Conclusively, nitrogen fertilization could increase the yield of flowerheads. The optimum application level of nitrogen fertilizer might be on the range of $265-295\;kg\;ha^{-1}$ in a mountainous soil.

This study was conducted to determine the anti-inflammatory effect of essential oil extracted from the wood of Chamaecyparis obtusa Sieb. et Zucc. Endl. (Cupressaceae). The essential oil was extracted from the wood of C. obtusa by hydrodistillation method, and conducted the analysis on the chemical composition of the extracted C. obtusa wood oil through GC-MS. The major constituents of the oil were found to be: ${\alpha}-pinene$ (11.4%), cadinene (5.4%), ${\delta}-cadiene$ (9.0%), ${\tau}-muurolol$ (22.2%), ${\alpha}-cadinol$ (20.8%) etc. We attempted to identify the anti-inflammatory activities of the oil when it is injected in the lipopolysaccharide (LPS)-stimulated RBL-2H3 cells, along with its effects on the secretion of interleukin-4 (IL-4), interleukin-13 (IL-13), ${\beta}-hexosaminidase$. According to the cell viability analysis conducted by MTT assay, the oil in $10^{-7}{\sim}10^{-5}%$concentration showed no effect on the cell viability. After RBL-2H3 cells treated by LPS stimulation were exposed to $10^{-7}%$ concentration of C. obtusa wood oil, the expression levels of IL-4, IL-13 within the cell were observed to remarkably decrease. Also, it was attenuated the release of ${\beta}-hexosaminidase$ from mast cells to a significantly meaningful level. These results suggest that C. obtusa wood oil exerts the anti-inflammatory effect, by regulating the expression of inflammatory cytokines, which is a valuable feature to be highly utilized as the functional materials in the future.

현재 합성 산화방지제에 대한 독성에 따른 사용 우려로 인해 천연 산화방지제에 대한 관심이 지속적으로 증가되고 있으나 천연 산화방지제 역시 한정적이다. 따라서 본 연구에서는 쿠민 종자의 에탄올 추출물의 산화 방지 효과와 유지 산화에 대한 산화 안정성을 평가해 보고자 하였다. 산화방지효과를 측정하기 위해 실시한 DPPH 라디칼 소거 활성 결과 0.5 mg/mL에서 73.4% 소거 활성을 보였으며, ABTS 양이온 라디칼 소거 활성 결과 1.0 mg/mL의 농도에서 50.1% 소거하였다. 총 페놀함량의 결과 $61.0{\mu}M$ tannic acid equivalent/g extract, FRAP 환원력 측정의 결과 $429{\mu}M$ ascorbic acid equivalent/g extract로 측정되었다. $100^{\circ}C$에서 9시간 열산화 시킨 옥수수기름에 첨가 후 산화안정성 평가 결과 초기 산화생성물을 측정하는 CDA의 양은 대조군보다 100 ppm의 농도로 첨가한 쿠민 종자 에탄올 추출물 첨가군이 13.4% 적게 생성되었으며, 이차 산화생성물을 측정하는 ${\rho}-AV$는 대조군에 비해 59.1% 적게 생성되었다. 이러한 유지산화 안정성효과는 쿠민 종자 에탄올 추출물에 존재하는 향기성분들에 의해 영향을 미친 것으로 판단된다. 본 연구 결과 쿠민 종자 에탄올 추출물에 존재하는 향기성분에 의해 산화방지와 유지 산화안정성의 우수한 효과를 나타낸 것으로 관찰되었으며 이는 유지가공식품 제조 시 불가피한 합성 산화방지제의 사용을 대체할 수 있는 천연 산화방지제로서의 가능성을 타진한 결과라고 사료된다.
