ABSTRACT
Propolis is a natural product collected by honeybees and has a large range of pharmacological activity, including antimicrobial, antitumoral, antioxidant andanti-inflammatory. Its use as a popular medicine is increasing all over the world, creating a need for quality control of the commercial products. In this study the levels of calcium and magnesium in commercial hydroalcoholic propolis extracts from varios states of Brazil were determined by atomic absorption flame spectrophotometry and different values were obtained for northern and southern states. This study can beextended to the analysis of metals that are harmfulto health. The results showed that the calibration curves were linear over a wide concentration range (0.5-4.0 miug.mL-1 for calcium and 0.05-0.4 miug.mL-1 formagnesium) with good correlation coefficients (0.999 and 0.988, respectively). Good analytical recovery (94%) was obtained. The proposed method showed adequate precision and relative standard deviation lower than 2%. The method is accurate and precise as well as having advantages such as simplicity and speed.
