Abstract

In this study, the cardinal and purple peanut testa were used as the raw materials for extracting polyphenol substances with ultrasonic and freeze-drying. Then the bacteriostasis and antifungal activities of the extracts were investigated by the methods of disc diffussion and equivalent against the Benzylpenicillin Sodium to certain bacteria. The results showed that, at the same concentration, bacteriostatic activity of the crude extract of cardinal peanut testa was stronger than that of purple peanuts. The inhibitory concentrations of crude extracts were up to 0.5 g/L for cardinal peanut testa, 1 g/L for purple peanut testa and equivalents against the Benzylpenicillin Sodium were 6000 U and 6400 U, respectively.
