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.

본 연구는 비자나무 숲을 대상으로 Z.-M. 학파의 방법으로 식물사회학적 연구가 이루어졌으며, 비자나무 숲에 대한 식생구조 및 관리방안을 중심으로 기술하였다. 그 결과는 다음과 같이 요약될 수 있다. 비자나무 숲은 수평적으로 난온대 상록활엽수림역의 저지대 및 구릉지에 발달하고 있었다. 총 50과 80속 95종으로 구성되어진 비자나무 숲은 종조성에 의해 비자나무-상산군락의 전형하위군락, 가는쇠고사리하위군락으로 구분되었으며, 서식처 환경조건에 대응하였다. 3~4층으로 구성된 비자나무 숲의 아교목층과 관목층은 과거 간벌이후 일제히 재생된 형태를 나타내고 있었으며, 난온대 상록활엽수림의 동백나무군강(Camellietea japonicae Miyawaki et Ohba 1963)을 특징짓는 진단종군으로 구성되어진 것이 특기되었다. 또한 임상의 경우 소엽맥문동, 십자고사리, 큰천남성 등의 순으로 기여도가 높았으며, 임연식생의 주요 구성종으로 대표되는 주름조개풀이 높은 기여도로 나타났다. 이러한 사실은 비자나무 숲이 지속적으로 인간간섭에 노출되어 있음을 나타내는 것이다. 비자나무의 치수는 반음지, 음지에서 높은 빈도로 출현하였다. 또한 비자나무 숲을 유지하기 위하여 삼림생태계의 구조와 기능을 쇠퇴시킬 가능성이 큰 강도간벌 대신에 난온대 상록활엽수림을 구성하는 교목수종을 간벌하되, 아교목 및 관목수종을 대상으로 밀도조절이 이루어져야 할 것으로 판단되는 바이다. 향후 지속가능한 비자나무 숲을 유지하기 위하여 식생구조와 관리방식에 대한 지속적인 모니터링이 이루어져야 할 것이다.

Lipoxygenase inhibitory acitivity of the methanolic extract of 60 different kinds of plant seeds was determined by a spectrophotometric method using a soybean lipoxigenase(SLO) and linolenic acid. Among the extracts examined, the methanolic extract of nutmeg(Myristical fragrans)seed showed the most potent SLO inhibitory activity. To isolate SLO inhibitor, hence, the defatted methanol extract was further partitioned with ether, ehtylacetate , and n-butanol , stepwise. The ether souble fraction was successively chromatographed on silica gel, Sephadex LH-20 and preparative TLC. Three phenolic compounds were isolated , and one of them showing a strong SLO inhibition activity was identified as a 2,6-dihydroxy-9-(3', 4', -dihydroxyphenyl)nonylphenone (IC50a=0.39$\mu\textrm{g}$/ml) by 1H-& 13C0NMR, IR, and MS spectroscopy.

In our program to search for new AMP-activated protein kinase (AMPK) activators from plants that exert potential anticancer property, we found that an EtOAc extract of Myristica fragrans (nutmeg) activated AMPK enzyme in human breast cancer MCF-7 cells. Two major diarylbutane-type lignans, macelignan and meso-dihydroguaiaretic acid (MDGA), were isolated as active principles from this extract. Treatment of breast cancer cells with two compounds induced cellular apoptosis, evidenced by cleavage of poly-(ADP-ribose) polymerase (PARP) and Ser 15 phosphorylation of p53. Moreover, macelignan and MDGA significantly inhibited the colony formation of MCF-7 breast cancer cells on soft agar. Intraperitoneal injection of macelignan and MDGA (20 mg/kg) suppressed the tumor growth of 4T1 mammary cancer cells. These results indicate that the chemopreventive effects of two major diarylbutane-type lignans from Myristica fragrans (nutmeg) may be associated with induction of apoptosis presumably through AMPK activation.

Macelignan is a bioactive compound isolated from nutmeg (Myristica fragrans Houtt.) which has been traditionally used for the food and pharmaceutical purposes. In this study, the activities of macelignan against vegetative cells and spores of Bacillus cereus were evaluated in vitro. Our results showed that the vegetative cells of B. cereus were significantly inhibited in growth by macelignan with minimum inhibitory concentration (MIC) of $4{\mu}g/mL$. The vegetative cells of B. cereus were completely killed with minimum bactericidal concentration (MBC) of $8{\mu}g/mL$ of macelignan. Killing time of macelignan against vegetative cells of B. cereus was very fast; endpoint of macelignan was reached after 4 hr of incubation at $4{\times}MIC$. Macelignan inactivated more than 3-log (99.9%) of spores/mL of B. cereus at the concentration of $100{\mu}g/mL$. Macelignan was found to be effective against vegetative cells and spores of B. cereus. These results suggest that macelignan might be good to be developed as a food preservative.

This study investigated the antioxidative and antimicrobial activities of nutmeg (water, ethanol extract and essential oil). The total phenol contents of water, ethanol extract and essential oil were 3.4%, 16.9%, and 3.2%, respectively. Hydrogen donating abilities of water, ethanol extract and essential oil at 1,000 ppm were 4.9%, 41.8% and 6.8%, respectively. The antioxidative activities in linoleic acid substrates were in the order of BHT > ethanol > extract > ${\alpha}$-tocopherol > essential oil > water extract. The antioxidative activities in linoleic acid emulsion substrates were in the order of BHT > water extract > essential oil > ethanol extract > ${\alpha}$-tocopherol. In antimicrobial activity, ethanol extract showed growth inhibition effect against Micrococcus luteus, Bacillus cereus and Salmonella enteritidis, and the essential oil showed growth inhibition effect against Micrococcus luteus. However, no antimicrobial activity of water extract was observed. The nitrite-scavenging abilities of water, ethanol extract and essential oil at 1,000 ppm were 4.5%, 28.8% and 98.8%, respectively, and the ACE inhibitory activities were 0.2%, 11.0% and 10.0%, respectively.

A novel sampling method of the headspace poly(dimethylsiloxane) (PDMS) mini-disk extraction (HS-PDE) was developed, optimized, validated and applied for the GC/MS analysis of spices flavors. A prototype PDMS mini-disk (8 mm outer diameter, 0.157 mm thickness, 9.4 mg weight) has been designed and fabricated as a sorption device. The technique uses a small PDMS mini-disk and very small volume of organic solvent and less sample size than the solvent extraction. This new HS-PDE method is very simple to use, inexpensive, rapid, requires less labor. Linearities of calibration curves for ${\alpha}$-pinene, ${\beta}$-pinene, limonene and ${\gamma}$-terpinene by HS-PDE combined with GC/MS were excellent having $r^2$ values greater than 0.99 at the dynamic range of 6.06~3500 ng/mL. The limit of detection (LOD) and the limit of quantitation (LOQ) showed very low values. This method exhibited good precision and accuracy. The overall extraction efficiency of this method was evaluated by using partition coefficients ($K_p$) and concentration factors (CF) for several characteristic components from nutmeg and mace. Partition coefficients were in the range from $2.04{\times}10^4$ to $4.42{\times}10^5$, while CF values were 0.88-15.03. HS-PDE was applied successfully for the analysis of flavors compositions from nutmeg, mace and cumin. The HS-PDE method is a very promising sampling technique for the characterization of volatile flavors.
