Antiozidant Properties of Different Solvents Eztracts from Three Edible Mushrooms
Three edible mushrooms are popular in China, including Lentinula edodes, Agaricus bisporus and Pleurotus geesteranus. Their hot water, 70％ ethanolic and 70％ acetone crude extracts were prepared and antioxidant properties were evaluated. 70％ Ethanolic extracts showed strongest scavenging abilities on DPPH radicals. The hot water crude extracts from three mushrooms exhibited excellent scavenging abilities on hydroxyl radicals, and for Agaricus bisporus, three solvent extracts showed higher scavenging abilities. Reducing powers of hot water and 70％ ethanolic extracts were excellent and increased sharply with the increased concentrations. In the same conditions, the sequence of antioxidant capacity was Agaricus bisporus>Pleurotus geesteranus>Lentinula edodes, and hot water and 70％ ethanolic crude extracts were better than 70％ acetone crude extracts.
