Abstract
The purpose of this study was to determine the antimicrobial activity of rosella infusa ( Hibiscus sabdariffa L.). Antimicrobial inhibition test using infusa of rosella ( Hibiscus sabdariffa L.) against Staphylococcus aureus and Escherichia coli bacteria at a concentration of infusa 100%; 75%; and 50%. The concentration has highest potential antibacterial of infusa for Staphylococcus aureus is 100% witch has diameter of 13.6 mm and for Escherichia coli bacteria is 100%, its show that diameter of zone inhibitory zone is 13.3 mm. The Results of phytochemical screening show that infusa of rosella ( Hibiscus sabdariffa L.) contains flavonoids, saponins, and tannins. Based on the data above show that the infusa of rosella flower has high antibacterial potential. Keywords: Hibiscus sabdariffa L., antimicrobial activity , Staphylococcus aureus, Escherichia coli
