Abstract

Abstract: Backround - Shallots (Allium cepa L) is one of  the plant that can be used as a traditional medicine. Method - This study was performed by using onion leaf to determine the inhibitory against the growth of Escherichia coli. Onion leafs extracted by maceration using 95%  alcohol. The extract of the Onion leaves was diluted with distilled water to reach concentration of 1000 ppm, 3000 ppm, and 10,000 ppm. The test of inhibition effect of the extract of onion leaves was performed by using the papper disc method. Results - The results showed all the leaves of onion extract concentration did not produce a clear zone on the media. Conclusion - onion leaf extract has no inhibition on the growth of the bacterium Escherichia coli.
