The polyphenols were extracted from peanut seed testa by ultrasonic-assisted extraction with 70% of ethanol as solvent. The crude extracts were purified,and the composition and antibacterial activi-ty of the polyphenols against common contaminated bacteria were investigated. The results indicated that the contents of polyphenol, flavone, procyanidins and resveratrol in peanut seed testa polyphenols were 64. 45%, 12. 76%, 81. 90% and 0. 005%, respectively. The polyphenols from peanut seed testa had strong inhibitory effects on bacteria, while it had no significant effect on fungus, and the antibacterial ac-tivity increased with the mass concentration of the polyphenols increasing.
