Efficacy of coffee peel extract as natural antimicrobial in coconut oil soap to against staphylococcus aureus

Abstract

The aim of the study was to evaluate the efficacy of coffee (Coffea canephora) peel extract as natural antimicrobial in coconut oil soap to against Staphylococcus aureus. S aureus, a pathogenic bacteria, was common to be found on human skin. By using Minimum Inhibitory Concentration (MIC) and inhibition zone, the antimicrobial activity of coffee peel extract were 16,7 + 7,22% and 0,38 + 0,21 mm, respectively. Phytochemical compounds of coffee were caffeic acid, cathecin, coumaric acid, gallic acid, hesperetin, kaempferol, hesperidin, luteolin, quercetin. Antimicrobial activity of coffee peel extract showed to be potential as natural antimicrobial in coconut oil soap to inhibit S. aureus.
