The purpose of this study was to determine the levels of flavonoids contained in the sembung leaf methanol extract. To identify the flavonoid content, Spectrophotometry UV-Vis method. Further, the analysis of methanol extract flavonoid in sembung leaves was carried out at a wavelength of 382 nm with successive absorbance values of 0.094; 0.090; 0.084. The total content of flavonoids in the sample was calculated by calibrating the absorbance value of the example with a standard linear equation of quercetin, y = 0.060 x -0.016 with a correlation coefficient (R2) = 0.997, and; the average total flavonoid content in the methanol extract of the leaves was 0.175%.
