A method for isolation and qantitative determination of anemarsaponin B from the rhizomes of Anemarrhena asphodeloides has been developed. Isolation of anemarsaponin B was achieved by silica gel and RP-18 column chromatography. The HPLC method for quantitative determination of anemarsaponin B provided a method for standardization of the crude drug. It suggested that the content of anemarsaponin B in Anemarrhena asphodeloides is about 0.12-1.48%.

여포 상피세포에 우수한 모발성장 촉진효과를 보이는 minoxidil의 단점을 보완하고자 대체의학제재로서의 모발 성장 촉진제로 지모를 연구하였다. 지모과(知母科)의 뿌리식물인 지모(知母)는 해열제, 항 당뇨병, 항우울제, 항염제 등으로 이용되고 있는 한국의 전통적인 약용식물이다. 지모 에탄올 추출물을 마우스의 등에 도포하여 관찰하였는데 모든 그룹의 마우스에서 체중과 음식 섭취량은 유의한 차이를 보이지 않았다. 지모 에탄올 추출물은 혈청 조성의 변화 없이 왕성한 모발성장 촉진효과를 보임으로써 향후 모발성장 촉진제로서 유용한 가치가 있으리라 사료된다.

1. Objective This study was aimed to screen the potential antitumor activity of one kinds of Korean medicinal herb extracts against cancer cell lines and to evaluate the growth inhibition effect of L-1210 and S-180 cancer cell lines. 2. Methods It confirmed Anemarrhena asphodeloides extracts to screen the potential antitumor activity. Then, it was extracted with 4 kinds of solvents ; hexane, ethyl acetate, butanol and $H_2O$, and the Growth inhibition effect of these extracts were determined against cancer cell and normal cell. The results were as follows : The IC50(50% inhibitory concentration) values of Anemarrhena asphodeloides extracts were shown to be $253{\mu}g/ml$ against L-1210 cell lines. The IC50 values of ethyl acetate extracts were shown to be $915{\mu}g/ml$ against L-1210 cell lines. The IC50 values of butanol extracts were shown to be $52.3{\mu}g/ml$, $485{\mu}g/ml$ against L-1210, S-180 cell lines, respectively. The butanol extracts were more selectively effective than other extracts to cancer cell lines. 3. Conclusion From these data, it could be concluded that the Anemarrhena asphodeloides extracts to the Growth inhibition effect of L-1210 and S-180 cancer cell lines.

지모 (Anemarrhena asphodeloides)는 탁월한 해열작용과 진정작용을 갖는 한약재로 한국, 중국, 일본에서 널리 이용되어 왔다. 본 연구에서는 먼저 국내 연구소에서 형태학적 분류 결과 지모로 확인된 3종의 식물체를 수집하여 엽록체 DNA의 trnL-F 염기서열을 분석하였다. 분석 결과, 국내 연구기관에서 보관중인 지모 식물체들이 모두 동일한 trnL-F의 염기서열을 보여서, 형태학적 분류와 계통유전학적 분류가 동일함을 확인하였다. 최초로 얻어진 지모 trnL-F 염기서열은 NCBI database에 등록하였다. 다음으로 국내 한약재 시장과 중국 한약재 시장에서 유통 중인 지모 한약재를 다량 구입하여 trnL-F의 염기서열을 분석하였다. 그 결과, 유통 중인 지모 한약재들이 모두 기원식물과 동일한 TrnL-F의 염기서열을 보여서 지모 약재의 경우 진품이 유통되고 있음을 알 수 있었다. TrnL-F의 염기서열로 계통수를 작성한 결과 지모는 아스파라거스목 (Asparagales), 용설란과 (agavaceae)에 속한 것으로 보여 졌다. 엽록체 rbcL 유전자 염기서열로 얻은 계통수와 비교한 결과 trnL-F 계통수와 rbcL 계통수가 비슷한 결과를 보여주어서 분자유전학적 분류에 두 유전자가 상호보완적으로 이용될 수 있음을 확인하였다.

A pyridyl alkaloid, 3-pyridylcarbinol (1) and benzoic acid derivatives, 4-hydroxy benzoic acid (2), 4-hydroxyactophenone (3), vanilic acid (4), and benzoic acid (5) were isolated from the rhizomes of Anemarrhena asphodeloides on the basis of spectroscopic and physicochemical analyses including 1D- and 2D- NMR techniques as well as by comparison of their data with the published values. Compounds 1 - 5 were isolated for the first time from this plant source.

EtOAc soluble part of MeOH extract of Anemarrhena asphodeloides rhizome was evaluated for the cytotoxicity against the five kinds of human tumor cell lines (A-549, SK-OV-3, SK-MEL-2, XF498 and HCT15) in vitro. Bioassay-guided fractionation of EtOAc soluble part led to the isolation of active compound which was identified as timosaponin A-III showed potent cytotoxic activity, but its genin, sarsasapogenin, did not show cell growth inhibition.

약용식물로 재배되고 있는 지모를 대상으로 McFISH 기법을 이용하여 45S와 5S rDNA 유전자의 염색체상의 위치를 확인하여 물리지도를 확립하였다. 2쌍의 45S rDNA는 1번 염색체의 단완 말단과 3번 염색체의 동원체 부위에서 관찰되었고, 1번 염색체의 signal이 3번 염색체에서의 signal보다 더 강하게 나타났다. 한 쌍의 5S rDNA signal은 45S rDNA signal과 함께 3번 염색체의 동원체 부위에서 관찰되었다.

Optimum condition for cultivation of Anemarrhena asphodeloides B$_{UNGE}$ and seasonal variation of saponin and sapogenin contents in the rhizome were investigated. It is confirmed that the best harvest time is 3rd year. Average contents of saponin in rhizome was 8.5% and 5.0%, in fibrous roots, being highest in winter. The facotrs of saponin content variation were seemed to be temperature and humidity. It was also proved that asphonin was the mixture of timosaponin A-III, timosaponin A-I and mangiferin. Mangiferin and isomangiferin were isolated from the flower.

This experiment was conducted to test the control effect of methanol extracts of 10 medicinal plants on apple storage diseases caused by Botryosphaeria berengeriana, Glomerella cingulata and Penicillium expansum. Out of the 10 medicinal plants, methanol extracts of Coptis japonica and Anemarrhena asphodeloides inhibited effectively the mycelial growth of B. berengeriana, G. cingulata and P. expansum in vitro, for which the inhibition ratios of the two plant extracts were 100.0% and 89.3%, 73.7% and 94.1%, and 100.0% and 51.6%, respectively. Spore germination of the three fungi was inhibited 100% only by C. japonica extract, but only P. expansum was inhibited 100% by A. asphodeloides extract. No lesion was formed y the fungi at 5$^{\circ}C$ up to 2 weeks after inoculation. Lesion sizes produced by the three fungi at the temperature ranges of 1$0^{\circ}C$ to $25^{\circ}C$ and infection of B. berengeriana and G. cingulata were inhibited by C. japonica extract, but not by A. asphodeloides extract, while no lesion was formed by the fungi at 5$^{\circ}C$. Infections of the fungi on apples were somewhat stimulated by A. asphodeloides extract.
