Abstract

Anemarrhena asphodeloides (Korean name "Ji-Mo") has been used for oriental medicinal purposes in Korea, China and Japan. In this study, 29 A. asphodeloides samples were collected including 3 certified A. asphodeloides plants and many commercially marketed A. asphodeloides products. Chloroplast trnL-F regions of the "Ji-Mo" samples were sequenced and used to identify whether the samples were genuine A. asphodeloides or not. As the result, the trnL-F sequences of all the "Ji-Mo" samples were shown to be identical and it was proven that commercially available medicinal products "Ji-Mo" are genuine A. asphodeloides. Phylogenetic tree of. A. asphodeloides using the trnL-F sequences was constructed and compared with phylogenetic tree using rubisco large subunit (rbcL) gene sequences. In these tree, A. asphodeloides was affiliated in the family Agavaceae in the order Asparagales. It is proven that trnL-F phylogenetic tree is useful to study taxonomic position of A. asphodeloides.

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.
