Abstract
|
|
|
|
The inhibitory effects of extracts from Agrimonia pilosa, which were obtained via different extraction methods, on the growth of Weissella viridescens and Leuconostoc carnosum were examined. Compared with simple water extraction, the sample extracted with alkalified water (pH 11) and 50% ethanol (pH 11) had 43% and 24% enhanced inhibitory effects on W. viridescens and Leu. carnosum growth, respectively. However, ultrasonic treatment did not exert a profound effect on the antimicrobial activity of A. pilosa regardless of the extraction solvent used.
