Quercetin content in propolis is influenced by geographical factors, differences in the season, climate, plants, bees, and the type of solvent. This study aims to determine differences of quercetin levels of propolis in the market area of ??Surakarta. Methods: This study uses observational analytic methods. Samples of propolis were sold in the market area of ??Surakarta. Sampling was done by purposive sampling as many as six brands of propolis which is divided into 6 groups: P1, P2, P3, P4, P5, and P6. Each group was measured five times. Determination of quercetin in propolis by using UV-Vis spectrophotometer method of Prussian Blue. Data were analyzed for quercetin levels with one-way ANOVA statistical test using the computer program SPSS 17 for windows. Results: Average of quercetin levels of propolis samples obtained results P1 = 9.4440 0.06465 g/mL, P2 = 4.4760 0.08591 g/mL, P3 = 10.2700 0.04000 g/mL, P4 = 7.4120 0.06648 g/mL, P5 = 8.6780 0.03347 g/mL, P6 = 8.4960 0.10877 g/mL with p < 0.001. Conclusion: There are differences of quercetin levels of propolis in the market area of ??Surakarta. Keywords: Propolis, quercetin levels, UV-Vis spectrophotometer, Prussian Blue
