Subject of this research is propolis from Gejen RT 3 RW 2, Kerjo, Karanganyar. The samples were carried out by purposive sampling. Concentration of quercetin is determined by using UV-Vis spectrophotometer by Prussian-blue methode. Five samples are made for each extract. The data then analized using unpaired t-test by SPSS 17 for windows. Results: Averages of quercetin level in this research are 10,0480±0,53798 µg/mL in Ethanol extract propolis and 1,0440±0,06804 µg/mL in Water Extract propolis with p < 0,05.
