A study of the chemical composition and biological activity of propolis of varying geographic origin
Propolis is a resinous substance produced by honey bees from various plant sources. The present research focused on the chemical and biological study of ethanolic extracts of 22 different propolis samples obtained from different geographical regions. The samples were investigated initially by high performance liquid chromatography (HPLC) in order to see if they contained any of the common marker compounds used to assess the quality of propolis. The antimicrobial activity of the propolis samplesdoi:10.48730/yewn-x687 fatcat:d44to27fsndatmxfmafpzmro2e
