Background : Angelica species are representative medicinal plants and it has been used in traditional medicinal methods, especially, in the traditional Asian medicine. The Angelica species used in conventional medicine varies by country according to specific regulations, i.e. A. gigas Nakai in Korea, A. sinensis Diels in China, and A. acutiloba Kitagawa in Japan. Because of the similarity between the names among Angelica, they can be confused in the market. Methods and Results : In this study, twenty-four chloroplast insertion or deletion (cpInDel) markers were developed from chloroplast DNA of A. gigas Nakai and tested for the classification of Angelica species. Primer sets were designed from flanking sequences of the discovered InDel loci from chloroplast DNA of A. gigas Nakai using CLC Main Workbench with the following parameters : primer length = 18 - 26 bp (Opt. 23 bp); GC% = 50 - 70% (Opt. 60%); Ta = 55 - 62℃ (Opt. 58℃); product size range = 120 - 300 bp. Polymorphism and genotype analysis of 13 Angelica species were performed using the developed cpInDel markers. Conclusion : The 24 cpInDel markers developed in this study could be used for genetic diversity analysis and classification of Angelica species.

Background: Angelica gigas, A. sinensis, and A. acutiloba are commercially important in the herbal medicine market, and among them, A. gigas has the highest economic value and price. However, their similar morphological traits are often used for fraud. Despite their importance in herbal medicine, recognition of the differences between Angelica species is currently inadequate. Methods and Results: A multiplex polymerase chain reaction (PCR) method was developed for direct detection and identification of A. gigas, A. sinensis, and A. acutiloba. The gene for the distinction of species was targeted at ITS in the nucleus and trnC-petN gene in chloroplasts. The optimized multiplex PCR in the present study utilized each Angelica species-specific primer pairs. Each primer pair yielded products of 229 base pairs (bp) for A. gigas, 53 bp for A. sinensis, 170 bp for A. acutiloba. Additionally non-specific PCR products were not detected in similar species by species-specific primers. Conclusions: In the present study, a multiplex-PCR assay, successfully assessed the authenticity of Angelica species (A. gigas, A. sinensis, and A. acutiloba). and whole genome amplification (WGA) was performed after DNA extraction to identify, the species in the product. The detection method of raw materials developed in the present study could be applied to herbal medicine and health functional food management.

Background : In the herbal medicine market, Angelica gigas, Angelica sinensis, and Angelica acutiloba are all called "Danggui" and used confusingly. We aimed to assess the genetic diversity and relationships among 14 Angelica species collected from different global seed companies. Toward this aim we developed DNA markers to differentiate the Angelica species. Methods and Results : A total of 14 Angelica species, A. gigas, A. acutiloba, A. sinensis, A. pachycarpa, A. hendersonii, A. arguta, A. keiskei, A. atropurpurea, A. dahurica, A. genuflexa, A. tenuissima, A. archangelica, A. taiwaniana, and A. hispanica were collected. The genetic diversity of all 14 species was analyzed by using five chloroplast DNA-based simple sequence repeat (SSR) markers and employing the DNA fragment analysis method. Each primer amplified 3 - 12 bands, with an average of 6.6 bands. Based on the genetic diversity analysis, these species were classified into specific species groups. The cluster dendrogram showed that the similarity coefficients ranged from 0.77 to 1.00. Conclusions : These findings could be used for further research on cultivar development by using molecular breeding techniques and for conservation of the genetic diversity of Angelica species. The analysis of polymorphic SSRs could provide an important experimental tool for examining a range of issues in plant genetics.

Background : Angelica gigas is a monocarpic biennial or short lived perennial plant. A. gigas, also called Dang Gui or Korean Angelica, is a major medicinal herb used in Asian countries such as Korea, Japan and China. In Korea, we are using the roots of A. gigas, but, they are using Angelica sinensis in China and Angelica acutiloba in Japan to obtain many active constituents. The biggest problem in the using of A. gigas would be the confusion with A. acutiloba or A. sinensis. These three plants can't be distinguished by appearance. And the constituent ratios of the three plants are different. This confusion can cause an accident or the pharmaceutical effects do not meet the expectations. In this study, we developed chloroplast SSR markers that can distinguish A. gigas, A. acutiloba and A. sinensis. Methods and Results : We collected A. gigas, A. acutiloba and A. sinensis. and extrated DNA using CTAB method. The DNA was diluted to 10 ng/㎕ and kept -20℃. We designed the primer sets using CLC Main Workbench based on chloroplast DNA SSR region of A. gigas. PCR were performed on the three angelica plant samples (in 5 repeat). Conclusion : We made five primer sets from five SSR regions of A. gigas cpDNA. All of the primer sets amplified the amplicon effectively. Two of the 5 primer sets had polymorphism. We can distinguish A. gigas, A. acutiloba, and A. sinensis using the 2 primer sets

The root of Angelica tenuissima Nakai (Umbelliferae) has been used in traditional medicines of Korea as a headache, common cold and a fever remedy. A. tenuissima contains ferulic acid and various compounds of essential oil group such as limonene, 3-butylidenephthalide, γ-terpinene, neocnidilide, ligustilide, senkyunolide and neocnidilide. This study carried out to compare the contents of ferulic acid, z-ligustilide and n-butylidenephthalide between native and cultivated species of A. tenuissima by HPLC. The average contents of ferulic acid, z-ligustilide and n-butylidenephthalide indicated that native species (9 samples) were 0.060%, 0.616%, 0.025% and cultivated species (15 samples) were 0.037%, 0.141%, 0.029%, respectively. All samples were collected from different places in Korea.

This study was performed to investigate the discrimination of Angelica gigas, Angelica acutiloba and Angelica sinensis on the treatment of chromaticity and colorfastness. Angelica gigantis root has been used as a Korean traditional medicine for the treatment of woman disease. Natural dyes give us many great benefits, including diversified color, but no pollution. These studies were carried out acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was dyed with Angelica gigas, Angelica acutiloba and Angelica sinensis. The results of experiment showed as follows: In discrimination by dyeing, the colors of Angelica acutiloba and Angelica sinensis were very similar, but that of Angelica gigas was different. There were no differences among colors of materials using non-mordant. But dyeing with iron acetate and copper dichloride were showed dark in Angelica gigas than other angelica species.

An analysis of RAPD-PCR (random amplified polymorphic DNA-polymerase chain reaction) was performed with three Angelica species (A. gigas Nakai, A. sinensis (Olive.) Diels and A. acutiloba Kitag) in an effort to distinguish between members of these three species. Two arbitrary primers (OPC02, OPD11) out of80 primers tested, produced 17 species-specific fragments among the three species. Eight fragments were specific for A. sinensis, four fragments specific for A. gigas, five specific for A. acutiloba. When primers OPC02 and OPD11 were used in the polymerase chain reaction, RAPD-PCR fragments that were specific for each of the three species were generated simultaneously. Primer OPC02 produced eight species-specific fragments: four were specific for A. sinensis, one for A. gigas, and three for A. acutiloba. Primer OPD11 produced nine speciesspecific fragments: four for A. sinensis, three for A. gigas, and two for A. acutiloba. The RAPD-PCR markers that were generated with these two primers should rapidly identify members of the three Angelica species. The consistency of the identifications made with these species-specific RAPD-PCR markers was demonstrated by the observation that each respective marker was generated from three accessions of each species, all with different origins. We also performed the RAPD-PCR analysis with the dried Angelica root samples that randomly collected from marketed and from the OPC02 primer, obtained a A. gigasspecific band and the band were cloned and sequenced.

당귀는 우리 나라는 참당귀 (Angelica gigas), 중국은 중국당귀 (A. sinensis) , 일본은 일당귀 (A.acutiloba)를 각각 같은 용도의 한약재로 사용하고 있다. 일당귀는 과거부터 우리나라에서도 일부 재배되고 있으며, 중국당귀는 ‘97년 이후 종자를 도입하여 재배하였으나 실패하여 농가의 피해가 발생한다. 이들 종의 생산성과 중국당귀의 국내 적응성을 수원 (해발 50 m), 진부 (해발 500 m), 태백 (해발 700 m) 3개지역에서 시험하였던 바 얻어진 결과를 요약하면 다음과 같다. 1. 참당귀, 일당귀는 3개 지역 모두 정상적으로 생육되고 수확이 되었다. 2. 중국당귀의 생존율은 테백 70.3%, 진부 45.2%, 수원 4%로 수원에서는 7월 이후 고온기에 고사되었다. 3. 중국당귀의 10a당 수량은 태백 160 kg, 진부 127 kg, 수원 8 kg으로 태백, 진부에서는 수확이 가능하였으나 수량이 극히 낮았으며, 수원에서는 생산이 불가능하였다. 4. 중국당귀는 해발 500 m 이하에서는 생존율이 극히 낮으며, 해발 700 m 이상의 높은 지역에서는 생존은 가능하나 생산성이 낮아 국내생산은 어려운 것으로 나타났다.

당귀의 품종과 수집종의 구분 수단으로 내추대성과 추대성 당귀의 구분과 수입 약재와 국산 약재를 건재로 혼용하여 사용하였을 때 기원 식물을 판별하기 위해 RAPD based primer를 선발하고자 PCR을 수행한 결과는 다음과 같다. 임의의 10-mer primer와 20-mer primer 등 총 72개의 primer를 사용하여 3개의 내추대성 특이적인 primer를 찾았는데, URP04 primer에서는 1.7 kb 부근에서 내추대성 특이적인 band가 나타났고, OPD11 primer에서는 1.2 kb 부근에 band가 없는 것이 내추대성으로 나타났으며, OPP09 primer에서는 1 kb 부근의 major band가 없고 1.2 kb와 0.8 kb부근에 band가 있는 만추당귀 특이적인 band pattern이 나타났다. 한편 OPC02 primer는 참당귀내에서 내추대성과 추대성 4집단 모든 sample에서 똑같은 band pattern을 보였던 primer로써, 이 primer를 사용하여 국내산 참당귀를 중국당귀, 일당귀와 판별할 수 있었고, OPD11과 OPP09 및 URP04 primer는 참당귀내에서 내추대성과 추대성을 구분 할 수 있었던 primer들로써 이들 primer로도 참당귀를 중국당귀, 일당귀와 판별할 수 있었다.

RAPD 분석을 통한 marker선별과 건조약재의 비교, 그리고 내부형태 특징을 통해 당귀3종(種)을 구별할 수 있는 결과를 요약하면 다음과 같다. 1. 50개의 primer중 5개의 primer에서 당귀류 3품종을 모두 구별할 수 있는 특이적인 band가 나타났다. 2. 유연관계 분석에서 중국당귀와 일당귀가 참당귀보다 더 근연관계임을 알 수 있었다. 3. 신선한 잎과 건조된 약재에서 RAPD 재현성이 확인되어 RAPD 분석법을 통해 당귀감별에 응용할 수 있을 것으로 사료된다. 4. 뿌리 내부구조에서 중국당귀는 정상적인 2기사부와 2기목부에 덧붙여 일부 이상비대생장을 보였고, 일당귀나 참당귀의 도관절에 비하여 더 넓고 짧아 계통학적으로 훨씬 더 진화된 것으로 여겨진다. 5. 일당귀는 현저하게 두꺼운 코르크층이 발달한 반면 참당귀의 코르크층 아래에 5~7층의 후각세포층이 환상으로 발달하여 뚜렷한 대조를 이루었다.
