Abstract

According to several studies, Kangkung Pagar (Ipomoea carnea Jacq.) that have many beneficial properties. The
aim of this study are to characterize the secondary methabolites from ethanol extract and determine antibacterial
activity against Pseudomonas aeruginosa. Methode s of this study are maceration by ethanol, fractionation by
column chromatography and antibacterial activity assay by disc diffusion method. Melting point of compound
139-140ºC. The results from characterization by Uv-Vis and IR spectroscopy is flavan 3-ol or catechin. The
result of antibacterial activity against psudomonas aeruginosa had strong level of activity.
