This study aimed to investigate antioxidant activity of various extracts from fruiting bodies and mycelia of two Phellinus linteus strains and P. baumii. The Phellinus strains have cultivated on oak and mulberry logs. The fruiting bodies species were harvested from each Phellinus strain and used in this study. The tested items include: 2, 2’-azinobis[3-ethylbenzthiazoline]-6-sulfonic acid (ABTS), free radical scavenging assay and determination of total phenolics contents (TPC), ferric reducing antioxidant power assay (FRAP), and DPPH (1, 1-diphenyl-2- picrylhydrazyl) radical-scavenging activities. Different extractions with 60% Ethyl alcohol, 70% methyl alcohol and heat water were done on the mycellial and fruiting bodies samples of the mushroom species. The methyl alcohol extraction from fruiting body of P. linteus KACC93057P displayed the highest antioxidant activity on ABTS, FRAP, and DPPH assays. The ethyl acetate fraction was concentrated and subjected to an ODS column chromatography, followed by Sephadex LH-20 column chromatography. Finally six compounds 1-6 were detected by preparative reversed-phase HPLC.

Cellulose is the most abundant organic polymer constituent of the cell wall of green plants and of various forms of algae. The complexity of lignocellulosic biomass is a major challenge in industrial research. Most mushroom species that naturally grow on soil or wood possess cellulases and the corresponding enzymatic system and, potential candidates for the direct bioconversion of softwood polysaccharides into fermentable sugars. However, there have been fewer studies on mushroom cellulases than on fungi such as Trichoderma spp., exploit the full potential of mushroom cellulases. This review will focus on the current status ofmushroom cellulase research and applications and will provide insight into promising future prospects.
