Abstract
Ganoderma lucidum, a species of basidiomycetes, is known as an oriental medicine which has various biological properties. Recently, G. lucidum can be cultivated with several kinds of trees as a substrate. In this study, we prepared acetone extracts from the fruiting bodies (FBs) of G. lucidum cultivated with the pruned branches of mulberry, apple, plum, persimmon, cherry, oak and grapevine and evaluated their antioxidant properties. At 0.1 mg/mL, FB cultivated with grapevine chips showed the highest antioxidant activity (56.3% in the 1.1-diphenyl-2-picrylhydrazyl radical scavenging activity). At 0.2% (extracts-weight/oil-weight), the oil stability index of the FB cultivated with grapevine chips was highest. Total phenols contained in acetone extracts from the FBs correlated strongly with their antioxidant activities. These results indicated the possibility that the antioxidant activities and total phenol contents of the extracts from G. lucidum are affected by the substrates.
