Griff) include flavonoids, alkaloids, tannins, triterpenoids, phenols and saponins. Flavonoids function as antioxidants by stabilizing free radicals so that they can reduce cell damage due to inflammation, so testing the antioxidant activity of purple leaf extract to determine IC50 in purple leaf extract as an antioxidant. This type of research is an experimental research. Calculation of IC50 using UV-Visible spectrophotometric method with DPPH at a wavelength of 518 nm with the standard used is ascorbic acid. The concentration of purple leaf extract was 105µg/mL, 115µg/mL, 125µg/mL, 135µg/mL, 145µg/mL. The results of the measurement of the antioxidant activity of purple leaf extract obtained data based on the IC50 value at a concentration of 84.91μg/mL. The IC50 results obtained were compared with the inhibition value of Ascorbic Acid solution with various concentrations of 10 g/mL,&nbsp; 12 g/mL, 14 g/mL, 16 g/mL, 18 g/mL, it was concluded that the antioxidant activity of purple leaf extract was strong.</p><br/><p>The following message is being delivered on behalf of Jurnal Insan Cendekia. ________________________________________________________________________</p>
