Abstract

As a first step for improvement of breeding and productivity of Epimedii Herba, the patterns of components and the difference in icariin, a main component of this plant, in compliance with seasons and places of collection were evaluated by HPLC. As a result, the patterns of components in samples collected in July-September were shown to be markedly increased compared to those collected in May. Corresponding to the alternations of the pattern, the amount of icariin, which was estimated to be 0.017% in May was found to be increased markedly up to 0.82% in September. The samples collected at Chul-won district showed the highest icariin contents (0.94%), however, those collected in China was only 50% level (0.4%) of domestic ones. These results strongly suggest that the quality of Epimedii Herba might be quite different with respect to the seasons and places of the collection.

삼지구엽초의 번식과 재배법을 개발하여 자생지에서의 남획과 자연 소멸을 막는 동시에 양질의 삼지구엽초 생약을 확보하긴 위한 일련의 실험중 채취시기 및 생산지에 따른 주요성분의 함량차를 비교 검토하였던바 채취시기에 따라서는 여름보다는 가을(9월 증순)에 채취한 것이 icariin성분이 월등히 높았고, 재배산과 자연산간에는 자연산이 약간 높은 경향이었다. 한편 철원지역에서 채취한 지구엽초(0.94%)에 비해 중국산(0.4%)의 icariin함량은 절반수준에 불과하여 삼지구엽초는 채취시기 및 장소에 따라 품질의 차이 가 큰 것으로 사료된다.
