DPPH free radical scavenging activities of extracts from liquid culture of Acremonium terricola with different solvents.
DPPH-TLC and DPPH-microplate assays were used to determine the free radical scavenging activities of different solvent extracts from the mycelia and the fermentation broth of Acremonium terricola.The results revealed that all extracts had free radical scavenging activities.The free radical scavenging activities of the extracts were different with different solvents and 75% ethanol was the best.At the concentration of 5.0 mg·mL-1,the extracts from the mycelia and the fermentation broth of Acremonium terricola could decrease 63.75% and 91.23% of 0.2 mg·mL-1 DPPH free radicals after incubating at 37℃ for 10 minutes.
