This experiment was conducted to determine the quality and quantity of chemical compounds and the proper harvesting time of propolis form honey bee hives in Karaj. A completely randomized design with three treatments (propolis harvesting time) and six replicated (hives) were used. Propolis samples were collected from hives in June, July and August. Ethanol extract was prepared from samples and standard methods were used for evaluation. Methods of pholin, FRAP, and Alominium chloride were used to measure phenol level, felavenoide, and antioxidant patency respectively. The results showed that amount of phenol, felavenoide and antioxidant potency were 216.7 mg/gr, 61.69 mg/gr, and 3305.27 μmol respectively and antioxidant activity was 52.42%. these amounts were higher than the qualities of samples harvested in June and July.
