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).
