【 摘 要 】

Ganoderma lucidum (Leyss.:Fr.) Karst is one of the medicinal mushrooms, whichpossesses enviable antioxidant properties. Objective of this investigationwas to evaluate antioxidant activity, reducing power, scavenging abilities on1.1-diphenyl-2-picrylhydrazyl (DPPH) radicals and chelating effects onferrous ions of hot water extracts obtained from carpophore and spores ofthis mushroom. Hot water extract from carpophore (Gl-I) showed highantioxidant activity of 85.7 ± 0.7%, at 10 mg/ml, while antioxidant activityof hot water extract from spores (Gl-Is) was 9.2 ± 0.3% at 10 mg/ml. Reducingpower of Gl-I reached a plateau of 3.4 ± 0.1 at 20 mg/ml, and 0.3 ± 0.0 at 20mg/ml for Gl-Is. At 10 mg/ml, scavenging ability on DPPH radicals of Gl-Iincreased to 96.8 ± 2.5%, whereas Gl-Is scavenged DPPH radicals by 69.6 ±2.5% at 10 mg/ml. Gl-I chelated 81.6 ± 3.6 % of ferrous ions at 20 mg/ml,while the chelating effect of Gl-Is was 73.8 ± 1.7%. The antioxidativeactivities of hot water extracts from carpophore and spores of the mushroomG. lucidum were concentration dependent and increased with an increase in theconcentration.
