당귀는 약용으로 널리 사용되는 대표적인 다년생 식물이다. 다양한 당귀 계통의 유전적 다양성에 대한 정보는 당귀의 유전자원의 발굴 및 보존의 차원에서 매우 중요하다. 당귀는 현재 한국에 등록 된 중요한 약용 식물 종이지만, 다른 나라의 다른 유사한 종과 구별 할 수 있는 분자표지가 없는 실정이다. 그러므로, 본 연구에서는 HRM 분석을 통해 국내 토종 당귀계통인 참당귀를 식별하기 위해 유전체 염기서열의 핵리보솜 DNA 내부(ITS)영역에서 단일염기다형성(SNP) 분자 표지를 개발하였다. 본 연구에서는 또한 5가지 당귀계통들의 혼합된 염색체 DNA 시료를 이용하여 HRM 분석을 수행하였으며, 최종적으로는 혼합된 염색체 DNA의 다양한 비율을 사용하여 혼용되는 대표적인 당귀계통인 참당귀와 중국 당귀를 재료로 HRM 분석을 진행하였다. 그러므로, 본 연구에서 개발된 SNP 분자표지는 다양한 지역 또는 국가에서 서식하는 당귀 계통들의 신속한 확인을 위해 매우 유용하게 이용될 것으로 생각된다.

Eight species of the genus Angelica in Korea were examined for the activity of affecting drug metabolism and for the presence of coumarins. The results showed that various parts, especially roots and fruits of Angelica plants had strong effects on drug metabolism and that they contained various derivatives of coumarins.

A flavone glycoside was isolated from the roots of Angelica gigas (Umbelliferae) and identified as diosmin $[diosmetin-7-O-{\alpha}-{_L}-rhamnopyranosyl \;(1{\rightarrow}6)-{\beta}-{_D}-glucopyranoside]$ by spectroscopic methods. This is the first report of a flavone gylcoside from Angelica species.

The ethanol extracts from Angelica gigas Nakai and Angelica acutiloba Kitagawa were fractionated to diethyl ether and aqueous partitions. Both partitions had strong antimutagenic effect on the MNNG (N-methyl-N-nitro-N-nitrosoguanidine) by Ames mutagenicity test. Diethyl ether fractions exhibited the greatest antimutagenic effect suppressing the mutagenicity of MNNG with inhibition of 78-80%. The ethanol extracts from both species showed the inhibitory effect on the growth of several human cancer cell lines. Especially, the diethyl ether fraction from ethanol extracts was most effective on human hepatocellular carcinoma cells, inhibiting 90-95% of cell growth. However, the aqueous fractions had least inhibition activity on many cancer cells. There was little cytotoxicity on human normal liver cell by ethanol extracts. Diethyl ether fraction from Angelica gigas Nakai ethanol extract had cytotoxicity less than 20% on human normal liver cells, compared with that from Angelica acutiloba Kitagawa ethanol exract. The adding of 0.5 (g/l) of diethyl ether fractions of Angelica gigas Nakai or Angelica acutiloba Kitagawa increased immune activity by enhacing human B and T cells up to three to four times. It was proven that diethyl ether fraction (0.7 g/1) from Angelica gigas Nakai could control blood pressure by suppressing angiotensin converting enzyme activity up to 98%. From TLC, it was appeared that both of diethyl ether partitions had umbelliferon, known to one of active substances from Angelica gigas Nakai and Angelica acutiloba Kitagawa.

다양한 지역에서 채취한 참당귀(Angelica gigas Nakai)의 잎, 줄기, 뿌리에서 내생균을 분리하였다. 내생균 균주는 형태적특징과 ITS (internal transcribed spacer) 지역의 염기서열을 이용하여 동정하였다. 총 35종의 내생균이 동정되었다. 내생균의 다양성은 참당귀의 조직에 따라 다르게 나타났다. 분리된 내생균은 참당귀 점무늬병균 Phoma sp. Y11 균주와 대치배양하여 항균활성을 측정하였다. 총 14종의내생균이균주 Y11에대해억제효과를나타내었다. 본 연구는 참당귀에서 분리한 내생균이 참당귀의 점무늬병에 대한 생물학적 방제제로 사용될 수 있다는 것을 제시하고 있다.

Objectives : Angelicae gigas, A. sinensis and A. acutiloba are three types of plants used as Angelicae Radix (Dang-Gui). Many doctors of Korean medicine want to know the difference in clinical use of these three species. This study aimed to compare the hemoglobin-related activity of the extracts of Angelicae gigas, A. sinensis and A. acutiloba roots by measuring the intensity of binding oxygen to hemoglobin using Raman spectroscopy. Methods : Hemoglobin activity was measured by chemical analysis and Raman spectroscopy to compare the pharmaceutical efficacy of three Angelica root extracts. The oxygenated hemoglobin intensity, blood decursinol and acetylcholinestrase(AChE) concentration in mice were measured. In addition, the effects of three Angelica root extracts on oxygenated hemoglobin intensity, decursinol and AChE concentration in red blood cells (RBC) from human were also investigated. Results : The contents of decursin, decursinol and decursinol angelate, which affected physiological activity and RBC properties, were higher in the extract of A. gigas root than in those of A. sinensis and A. acutiloba roots. Moreover, oxygenated hemoglobin intensity in the A. gigas extract was higher than that of other two species in the blood of mice and human RBCs. Also, the blood decursinol and AChE concentrations of A. gigas root extract were higher than that of A. sinensis and A. acutiloba roots. Conclusions : These results suggest that A. gigas is more effective in treating disease related oxygen deficiency in RBC deformation under oxidative stress.

Karyotype analysis and chromosomal localization of 5S and 45S rDNAs using multi-color fluorescence in situ hybridization (McFISH) technique were carried out in two Angelica species. The numbers of diploid chromosomes were the same in two same in two species as 2n=22, however the lengths of chromosomes were varied from 4.25 to 6.50 ${\mu}{\textrm}{m}$ in A gigas and 4.95 to 8.50 ${\mu}{\textrm}{m}$ in A acutiloba. The chromosomes of A. gigas were composed of five metacentric and six submetacentric pairs, while those of A. acutiloba were six metacentic, one submetacentric and four subtelocentric paris. In FISH experiments, the numbers and size of 45S rDNA signals were varied between two species, however dach signal of the 5S rDNA was observed in two species.

Sa-Mul-Tang (Si-Wu-Tang, SMT), a kind of Chinese medicine, has been used for the hemato-deficient disease for hundreds of years. In this work, investigations on the anti-anemic activity of an aqueous extract of SMT were undertaken in order to find the pharmacological basis for the ethnomedical use of the formulation. Three kinds of Angelicase species, such as Angelica sinensis, Angelica acutiloba, and Angelica gigas, were used for preparing the water extracts of SMT. Anemic model rats were induced by the treatment of phenylhydrazine (40 mg/kg/day, i.p.) for 4 days. After the treatment of phenylhydrazine, rats were divided into several groups for their different treatment of three kinds of SMT. Red blood cell (RBC), hemoglobin (Hg), and hematocrit (Hct) were determined on the day 0, 3, 6, 10, 14 after the treatment of SMTs and erythrocytes deformabilities were also determined at the end of experiments. Oral administration of SMT (1g/kg/day) for 14 days did not ameliorate drug-induced anemic states evaluated by RBC counts, Hg contents, and Hct values. However, the erythrocyte deformabilities were improved in phenylhydrazine-treated group by the administragest that SMTs (p<0.05). Especially, these effects were high in the Angelica acutiloba group. These results suggest that SMTs have an ameliorative effect on blood rheology related to the blood stasis syndrome in oriental diagnostics not on the blood deficient states related to the anemic syndrome.

한방에서 당귀로 쓰여지고 있는 참당귀(Angelica gigas)와 일당귀 (A. acutiloba)의 추출물로 3종의 그람양성균, 2종의 그람음성균과 1종 효모에 대한 항균활성을 조사한 결과는 다음과 같다. 참당귀 지상부와 지하부 추출액의 항균활성은 ethyl acetate 분획물에서만 나타났는데 지상부 추출액에서는 그람양성균인 S. aureus에 대한 항균활성이 가장 강했고, 지하부 추출물에서는 그람양성균인 B. subtilis와 그람음성균인 E. coli에 대한 항균활성이 가장 강했다. 일당귀 추출액의 항균활성은 지상부 추출액은 n-hexane 분획물에서 지하부 추출액 은 water분획물에서 전혀 나타나지 않았으며 지상부와 지하부 추출액의 ether분획물에서 가장 강했다. 효모 S. cerevisiae에 대해서는 항균환성이 전혀 나타나지 않았다.

Background: In the herbal medicinal industry, Angelica gigas Nakai, Angelica sinensis (Oliv.) Diels. and Angelica acutiloba (Siebold & Zucc.) Kitag. are often confused, because the roots of the three species can not be distinguished by their appearance. This confusion can cause serious side effects. In this study, we determined the origins of Angelica roots distributed in the Korean market using the simple sequence repeat (SSR) markers developed based on the A. gigas chloroplast DNA sequence. Methods and Results: We collected twenty seven A. gigas and three A. acutiloba samples from the Seoul, Daegu, and Cheongju herbal medicinal markets. Fifty sections of one collection were mixed and ground to make a powder, which was used for DNA extraction using the cetyl trimethylammonium bromide (CTAB) method. Chloroplast based SSR markers were applied to the DNA for the determination of the species. In addition, polymorphism was found in eight samples. The phylogenetic analysis showed that the A. gigas roots collected from herbal medicinal markets were clearly discriminated from A. sinensis and A. acutiloba even though they were grouped into four clusters. Conclusions: This study showed that chloroplast based SSR markers would help the discrimination of Angelica roots in the Korean herbal medicinal industry and the markers are useful to prevent confusion between Angelica roots.
