An effective analytical method of gas chromatography/mass spectrometry (GC/MS) was developed for the rapid determination of essential oils in the crude extract of Acorus species (Acorus gramineus, Acorus tatarinowii, and Acorus calamus). Major phenypropanoids (${\beta}$,${\alpha}$-asarone isomers, euasarone, and methyleugenol) and ${\beta}$-caryophyllene in Acorus species were used as marker compounds and determined for the quality control of herbal medicines. To extract marker compounds, various extraction techniques such as solvent immersion, mechanical shaking, and sonication were compared, and the greatest efficiency was observed with sonication extraction using petroleum ether. The dynamic range of the GC/MS method depended on the specific analyte; acceptable quantification was obtained between 10 and 2000 ${\mu}g/mL$ for ${\beta}$-asarone, 10 and 500 ${\mu}g/mL$ for ${\alpha}$-asarone, 10 and 200 ${\mu}g/mL$ for methyleugenol, and between 5 and 100 ${\mu}g/mL$ for ${\beta}$-caryophyllene. The method was deemed satisfactory by inter- and intra-day validation and exhibited both high accuracy and precision, with a relative standard deviation < 10%. Overall limits of detection were approximately 0.34-0.83 ${\mu}g/mL$, with a standard deviation (${\sigma}$)-to-calibration slope (s) ratio (${\sigma}$/s) of 3. The limit of quantitation in our experiments was approximately 1.13-3.20 ${\mu}g/mL$ at a ${\sigma}$/s of 10. On the basement of method validation, 20 samples of Acorus species collected from markets in Korea were monitored for the quality control. In addition, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed on the analytical data of 20 different Acorus species samples in order to classify samples that were collected from different regions.

국내 자생 수생식물인 노랑꽃창포와 창포를 수질 내 카드뮴(Cd) 제거용 식물재료로 이용하고자 Cd 축적과 내성을 조사하였다. Cd 농도에 따른 치사율을 근거로 Cd에 대한 반수치사량($LD_{50}$)을 계산한 결과, 노랑꽃창포는 $78.5{\mu}M$, 창포는 $47.6{\mu}M$로 나타났다. Cd 스트레스에 대해 노랑꽃창포에서는 POD와 SOD, 창포에서는 CAT와 SOD, 폴리페놀이 활성화되었다. 노랑꽃창포에서는 폴리페놀이 측정되지 않았다. 노랑꽃창포와 창포 모두 Cd 처리 농도가 증가하고 기간이 길어질수록 식물체 내 Cd 축적량이 증가하였고, 두 종 모두 지상부보다는 지하부 축적량이 현저하게 많았다. 지상부에 축적된 Cd 함량은 노랑꽃창포 $548.1mg{\cdot}kg^{-1}$(지하부 축적 대비 82.1%) 창포 $121.4mg{\cdot}kg^{-1}$(지하부 축적 대비 13.7%)로 두 종 모두 Cd 고축적식물로 확인되었으며, 특히 노랑꽃 창포가 Cd 축적능력과 내성이 우수하였다.

국내 자생 수생식물인 창포의 중금속 카드뮴(Cd)에 대한 생리적 구조적 장해를 알아보고자 본 연구를 실시하였다. Cd 농도에 따른 생장률, 광합성, 뿌리활력의 생리적 반응과 잎과 뿌리 조직의 해부학적 상해 반응을 조사하였다. 잎이 5매 전개된 식물체를 대상으로 Cd 농도를 반치사농도 범위이하 조건에서 0(control), 10, 25, $50{\mu}M$로 15일간 처리하였다. Cd에 대한 생리적 장해는 $10-25{\mu}M$, 구조적 상해는 $25-50{\mu}M$ 범위에서 나타났다. 생리적 장해의 경우 지상부(광합성)는 $10{\mu}M$, 지하부(뿌리활력)는 $25{\mu}M$에서 발생하였다. 구조적 상해의 경우 지상부(엽육조직)와 지하부(뿌리조직) 모두 $25{\mu}M$에서 시작되었으나, Cd 농도가 증가할수록 엽육조직보다는 뿌리조직의 상해 정도가 현저하였다. Cd에 대한 창포의 생리적, 구조적 장해 반응을 고려할 때, Cd 오염지역에서 창포의 경관적 가치와 지속적인 생장을 유지할 수 있는 Cd 한계농도는 $10{\mu}M$ 정도인 것으로 확인되었다.

The insecticidal activities of 30 aromatic plant extracts against four insect pests were examined by direct contact application. Against Nilaparvata lugens female adults, Myzus persicae female adults, and Plutella xylostella larvae, at 5,000 ppm, >90% mortality was achieved in the methanol extracts of the rhizomes from Cnidium officinale, Acorus gramineus, Acorus calamus var. angustatus and Curcuma Ionga, the whole plant from Agastache rugosa, the fruits from Illicium verum and Piper nigrum, and the flower bud from Eugenia caryophyllata as well as Cinnamomum camphora steam distillate. Against Spodoptera litura larvae, all test plant extracts were ineffective. The plants described merit further study as potential insect-control agents against insect pests.

The effects of four extracts of medicinal herbs, Rubus coreanum, Acorus calamus, Morus alba and Rehmannia glutinosa on hair growth activity and acnes control were investigated. In the course of screening natural extracts for hair growth, we found that the extract of dried root of Rubus coreanum has the hair growth promoting effect. After topical application of these extracts to the back of C57BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. The growth of dermal papilla cells and mouse vibrissae hair follicle cultured in vitro, however, was not affected by treatment of these extracts. Furthermore these extracts do not possesspotent inhibitory effect on $5{\alpha}-reductase$ I and II activity and anti-bacterial effect on Escherichia coli , Propionibacterium acnes, Pityrosporum ovale, Staphylococcus aureus, Staphylococcus epidemidis, and Candida albicans. RT-PCR analysis showed that these extracts did notinduce mRNA levels of growth factors such as insulin-like growth factor-I, keratinocyte growth factor, hepatocyte growth factor and vascular endothelial growth factor in dermal papilla cells. These results suggest that Rubus coreanum has hair growth promoting effect. However, the effects of these materials on the hair growth promotion are not mediated through inhibition of $5{\alpha}-reductase$ I and II activity, stimulation of hair follicle cells and expression of growth factors in the dermal papilla cells.

Seven essential oils were tested for in vitro cytotoxicity against the cancerous cell lines A-549, HEp-2 and DLA and normal BRL-3A, NRK-49F and Vero cell lines using standard MTT, SRB and dye exclusion techniques. The A-549 cell line was found to be the most susceptible to all the essential oils. The essential oils of A. nilagirica, A. calamus and O. sanctum were found to be the more active against these cells with mean $CTC_{50}$ values of 17.75, 19.00 and $24.37\;{\mu}g/ml$, respectively. The essential oil of Acorus calamus was found to be the most potent with low $CTC_{50}$ values against the cancerous and comparatively higher $CTC_{50}$ values against the normal cell lines. Artemisia pellens and Pelargonium graveolens oils also showed potent activity. These oils merit further investigation to identify the active principles and nature of the anti tumor activity in animal models.

식물명 창포, 석창포를 비롯하여 수창포와 계손 등은 우리나라 옛날 고전에서부터 혼란스럽게 혼용되어 왔으며 오늘날에도 마찬가지이다. 따라서 본 연구에서는 이들의 정확한 실체를 규명하기 위해서 중국 고전과 우리나라 고전, 그리고 최근의 중국과 우리나라 식물지를 비교 검토했다. 중국에서는 창포와 석창포는 잎에 잎맥이 뚜렷하게 발달하는 Acorus calamus를 지칭하는 이름으로 사용되어 왔고, 수창포와 계손은 잎에 잎맥이 뚜렷하지 않은 A. gramineus를 지칭하는 이름으로 사용되어 왔음이 확인되었다. 그러나 우리나라에서는 석창포와 계손은 A. gramineus로, 수창포와 창포는 A. calamus를 지칭했으나, 이름들이 혼용되어 온 것으로 확인되었다. 혼용에 따른 혼란을 피하기 위해 계손과 석창포라는 이름을 사용하지 않고 A. calamus는 창포로, A. gramineus는 수창포로 부를 것으로 제안한다. 그리고 생물다양성협약에 대응하기 위해서는 한자로 표기된 식물명의 정확한 분류학적 실체를 규명해야 하며, 동시에 예부터 사용해왔던 한글로 표기된 식물명에 대한 연구가 필요함을 덧붙인다.

The structure of natural vegetation and soil condition in bog area of Woopo, Changnyeung, South Korea were observed. The vegetations in the investigated area could be classified into two groups; a typical bog vegetation with dominant species of Eleocharis mamillats, Acorus calamus and Persicaria hostatosagittata and the transitional vegetation of three neighboring areas. Interspecific correlation in the investigated area was very close. In the typical bog vegetatiion regions (region II, III, V, VI, VII, VIII and X) soil pH, field moisture capacity, available P content and exchangeable K were moderate. But, In the transitiional area I, with the highest humus content, field moisture capacity and exchangeable K Salix gracilistyla was dominant. In the region IV with the lowest humus and a ailable P content and with high soil pH Geophyta was a major component species. Also Acorus region IX with the lowest content of exchangeable K Therophyta was dominant and plant species was diverse due to weak water influence. The vegetation structure of the region IX was most different from that of the whole vegetation.
