Abstract

This study was conducted to investigate electron donating ability, antioxdative activity and nitrite-scavenging effect of solvent extracts from Gyrophora esculenta. The phenolic compounds of diethylether, butanol, petroleum ether and hexane extracts were 194.20$\mu\textrm{g}$/ml, 98.80$\mu\textrm{g}$/ml, 1.60$\mu\textrm{g}$/ml and 0.20$\mu\textrm{g}$/ml, respectively. Electron donating abilities of diethyleter and butanol extracts from Gyrophora esculaenta were 80.79% and 72.81%, respectively. Absorption of DPPH by diethyleter and butanol extracts sharply increaed at initial stage. Antioxidative activities of fiethylether and butanol extracts by peroxide values are rather high as compared to those of control, but low s compared to those of BHA. Nitrite-scavenging abilities of diethylether, butanol and petroleum ether from Gyrophora esculenta were 96.07%, 77.39% and 15.07%, respectively.
