This research aimed at getting the optimum solvent dielectric constant and ratio teter leaves to solvents on the highest antioxidant activity of teter leaves extract. Response Surface Methodology (RSM) was used for the optimization of extraction conditions with the experimental design was a Central Composite Design (CCD) in two factors, namely solvent dielectric constant and ratio of teter leaves to solvent. The results showed that the optimum treatment was solvent dielectric constant value 40.74 and the ratio of teter leaves to solvent 1:10.19 to produced teter leaves extract which had the highest antioxidant activity was 84.34% with IC50 was 161.988 ppm, extract yield was 17.41%, total phenolic content was 175.151 mg GAE/g extract, total flavonoid content was 82.60 mg QE/g extract, total tannin was 12.30 mg TAE/g extract and vitamin C was 82.30 mg AAE/g extract.
