Pogostemon cablin (Lamiaceae) has been widely used in traditional medicine. In this study, the antioxidant and antimicrobial activities of leaves from P. cablin extracts were investigated. The water extracts had the highest total phenolic content mg gallic acid equivalent/g of dry plant extract. Nevertheless, high levels of total flavonoid content were found in ethanolic extracts mg quercetin equivalent/g of dry plant extract. The highest antioxidant activities were found for the ethanolic extract (, μg/mL) by DPPH and ABTS scavenging assays, respectively. Both extracts showed moderate inhibition of superoxide inhibition () and nitric oxide (NO) production in concentration-dependent manner. Antibacterial activity was calculated by disk diffusion, minimum inhibitory concentration (MIC), and minimum bacterial concentration (MBC). The ethanolic extract had the greatest activity against methicillin resistant Staphylococcus aureus, methicillin sensitive S. aureus, and Streptococcus pyogenes with zone diameters of , , and mm, respectively. The corresponding MIC and MBCs were 5, 0.625, and 0.039 mg/mL. P. cablin extracts contain antioxidant and antibacterial properties that should be exploited for possible clinical application.
