국내 자생하는 야생버섯 추출물의 항산화 활성 및 베타 글루칸 함량을 알아보기 위하여 버섯추출물에 대한 DPPH 라디컬 소거능, ABTS + 라디컬 소거능, 총 폴리페 놀 함량, 베타글루칸 함량을 분석하였다. 수집 야생버섯 중에서 DPPH 라디컬 소거능과 ABTS 라디컬 소거능이 높은 버섯은 간버섯속(OK1071), 명아주자작나무버섯 (OK1090), 등갈색미로버섯(OK1094)이었다. 아질산염 소거능과 총 폴리페놀 함량은 간버섯속(OK1071)이 각각 74.2%와 37.7 mg GAE/g의 값을 나타내며 가장 높았다. 베타글루칸 함량은 조개껍질버섯(OK1040), 구름송편버섯 (OK1044), 간버섯속(OK1071)이 각각 47.8%, 43.9%, 41.8%로 높은 수치를 나타냈다. 본 연구결과로부터 야생 버섯들 중에서 항산화 활성 등이 우수한 버섯자원들이 존재하는 것을 확인하였으며, 기능성 소재로서의 활용가능 성이 높을 것으로 기대한다. 더 나아가 국내 버섯산업의 확대를 위하여 토종 버섯자원을 이용한 새로운 천연물 유래 생리활성 물질로 활용하기 위한 기초자료로 활용도가 높으리라 기대된다.

This study was executed to evaluate the immune activity, nitrite scavenging activity and ABTS radical scavenging activity against extracts of various concentration of ethanol solvent from Codonopsis lanceolata cultured at 6 local regions. The immune responses from both human T and B cell line was significantly enhanced in the cell growth compared to control while the cell growth was influenced at a certain period of culture. The results revealed that the cell growth of both human T and B cell was altered in a time dependent manner. The nitrite scavenging activity of ethanol extracts from various solvent concentration of C. lanceolata were affected by pH. At a pH of 1.2, the nitrite scavenging effect of all of the extracts tested observed higher than that of the other two pH ranges. There was no distinct detection of nitrite scavenging effects of the pH range 6.0. The ABTS radical scavenging activity was progressively increased in a dose-dependent manner, and the activity was the highest in 100% ethanol extract. The result from this investigation suggests that the extract of Codonopsis lanceolata could be an addition to basic medicine for immune modulation and natural food additives.
