Abstract

This study aimed to discriminate the geographical origins of domestic and chinese Wolfiporia extensa. They were subjected to oxygen (45.32 to 48.07%), carbon (38.09 to 40.12%), hydrogen (6.05 to 6.78%), and nitrogen (0.16 to 0.23%). Antioxidant activity was examined by DPPH free radical scavenging activity. According to the results of the experiment, no significant differences were found between domestic ($IC_{50}$, 7.25 mg/ml) and Chinese ($IC_{50}$, 8.35 mg/ml) W. extensa. However, as determined by the inorganic mineral contents were significantly different between domestic and Chinese W. extensa. The amount of potassium in domestic and Chinese W. extensa was and $33.14{\pm}17.27%$, $47.60{\pm}8.78%$, respectively. The results of this study suggested that the analysis of inorganic components by ED-XRF should be useful for origin identification of W. extensa.

본 연구는 국내산과 중국산 복령의 원산지를 판별하기 위한 방법을 모색하고자 진행되었다. 분석 결과 일반 성분은 산소 45.32-48.07%, 탄소 38.90-40.12%, 수소 6.05-6.78% 및 질소 0.16-0.23%로 국내산과 중국산 복령에서 유사한 값을 가짐을 확인하였으며, DPPH 자유라디칼 소거능 확인을 통한 항산화 활성 또한 유의적인 차이는 없었으나, ED-XRF (X-선 형광 분석기)를 이용한 무기원소 분석에서 국내산과 중국산 복령간에 차이점을 확인하였다. 중국산 복령의 경우 칼륨(K), 철(Fe)이 각각 $47.60{\pm}8.78%$와 $14.5{\pm}3.86%$로 확인되었으며 이는 국내산 복령($33.14{\pm}17.27%$, $9.13{\pm}4.83%$)보다 높은 수치를 보였다. 전반적인 실험 결과 ED-XRF 분석을 통한 무기원소의 차이를 확인할 수 있었으므로 향후 복령의 원산지 판별에 이를 이용할 수 있을 것이라 생각된다.
