Abstract

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).

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.
