초록

본 연구에서는 표고버섯 원목재배 방법을 통하여 생산한 버섯의 품종별 항산화 특성을 분석하였다. 원목재배 표고버섯 추출물의 총 폴리페놀과 총 플라보노이드 함량을 측정한 결과는 5.10~10.88 mg GAE/g과 0.76~5.78 mg QE/g으로 나타났으며, 원목재배용 표고버섯 품종 중에서 천백고가 다른 품종들에 비해서 가장 높게 나타났다(총 폴리페놀 10.88 mg GAE/g, 총 플라보노이드 5.78 mg QE/g). 원목재배 표고버섯 추출물의 DPPH 라디칼 소거 활성과 FRAP을 측정한 결과 추출물의 농도에 비례하여 전자공여능과 환원력이 증가하였으며, 원목 재배용 표고버섯 중에서 천백고는 0.2~2.0 mg/mL 농도 범위에서 38.19~90.11%과 0.075~0.231로 다른 품종들에 비해서 가장 높게 나타났다. 본 연구를 통해 원목재배용 표고버섯 품종에 따른 항산화 활성을 확인하였으며, 향후 원목재배용 표고버섯 품종 개발과 항산화 활성 연구에 있어 기초 자료로서 활용될 수 있을 것이다.

We investigated the antioxidant activities of nine Lentinula edodes varieties cultivated on oak log. The total polyphenol content (TPC), total flavonoid content (TFC), and antioxidant properties of L. edodes (varieties: Dasanhyang, Chunbaegko, Poongnyunko, Soohyangko, Baekwhahyang, Chunjang 1ho, Chunjang 2ho, Sanlim 5ho, and Sanlim 7ho) were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay and the ferric reducing antioxidant power (FRAP) assay. The TPC and TFC of mushroom extracts ranged from 5.10 to 10.88 mg gallic acid equivalent (GAE)/g and 0.76 to 5.78 mg quercetin equivalent (QE)/g, respectively. In addition, mushroom extracts exhibited DPPH radical scavenging activity of 24.22~90.41%, 2.0 mg/mL and FRAP of 0.056~0.231, 2.0 mg/mL. The Chunbaegko variety showed the highest TPC (10.88 mg GAE/g), TFC (5.78 mg QE/g), DPPH activity (38.19~90.11%, 0.2~2.0 mg/mL), and FRAP (0.075~0.231, 0.2~2.0 mg/mL).
