Abstract Sembung rambat (Mikania micrantha Kunth) is one of the medicinal plants widely used in traditional medicine and belongs to the Asteraceae family. Its leaves contain various phytochemical compounds, including alkaloids, flavonoids, tannins, and steroids. Among these compounds, flavonoids play a significant role as natural antioxidants and possess strong pharmacological activities. This study aimed to determine the flavonoid content and antioxidant activity of the ethanolic extract of sembung rambat (Mikania micrantha Kunth) leaves. This study was experimental research design using a purposive sampling technique. The flavonoid content was determined using the colorimetric method, while antioxidant activity was evaluated using the DPPH (2,2-difenil-1-pikrilhidrazil) free radical scavenging assay. All analyses were performed using UV-Visible spectrophotometry. The results showed that the ethanolic extract of sembung rambat (Mikania micrantha Kunth) leaves contained a total flavonoid content of 38.472 mg QE/g extract and exhibited an IC₅₀ value of 87.5702 ppm, indicating strong antioxidant activity. The conclusion of this study showed that the ethanolic extract of sembung rambat (Mikania micrantha Kunth) leaves contains flavonoid compounds and demonstrates strong antioxidant activity, indicating its potential as a natural source of antioxidant.
