Chemical Composition and Antioxidant Activity of Propolis

Different products from a unique propolis extract obtained by using various solvents such as hydroalcoholic, glycolic (98% propylene glycol), and glyceric solutions, and oil, as well as in powder form, named ESIT12, were prepared. The molecular composition of the different preparations was evaluated and their antioxidant activity determined.

Chemical composition of propolis samples from north Algeria was characterized by chromatographic and spectroscopic analyses. High-performance liquid chromatorgaphy with diode-array detection (HPLC-DAD) fingerprint of the methanol extracts allowed the definition of two main types of Algerian propolis (AP) directly related to their secondary metabolite composition. Investigation of two
