Hass plants from various types of solvents show some activities such as antioxidants and antibacterials. In this research has been studied antioxidant activity test from wedelolactone isolate resulted from Eclipta alba (L.) Hass leaves. The isolation process is carried out conventionally by means of maceration, partition, and column chromatography and characterized by TLC, LCMS and UV-Vis and NMR spectroscopy. The results showed that wedelolactone isolate had antioxidant activity of IC50 at concentration (5.6 ± 0.5) ppm.
