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.
In DNA level, genetic study of Angelica species was firstly conducted to discriminate the bolting-resistant or low bolting variety, so called as Manchu, from other Korea collected lines and also this technuque was applied to identify the origin of commercial dried materials obtained from current oriental medicinal market. By RAPD analysis with 72 primers including sixty of 10-mers and twelve of 20-mers, respectively, three primers, which were related to the bolting resistant traits of Angelica gigas, were identified. Comparing the RAPD bands, URP04 primer showed the 1.7 kb specific band, which seemed to be related to delaying bolting traits, since it was observed only in Jinbu elite lines but not in others. On the other hand, since 1.2 kb band amplified by OPD11 was observed in other collected lines but not in Manchu var. and Jinbu line, this primer also could be considered as a selection marker for identifying bolting resistant or delaying bolting traits. In the same manner, since OPP09 did not show 1 kb major band but produced 0.8 kb and 1.2 kb bands in Manchu var., these three bands amplified by the primer could be considered one of the important key specifying Manchu var. related with the trait of Angelica gigas. OPC02 primer showed the same band patterns in all Korean collected lines, but not in other foreign introduced lines, such as A. sinensis from China, and A. acutiloba from Japan. Since these four RAPD primers, OPD11, OPP09, URP04, and OPC02 showed the specific polymorphisms in Angelica species, thus, these were useful to discriminate the three Angelica species, A. gigas, A. sinensis, and A. acutiloba.
