  Propolis is a resinous substances collected by honeybees from various plant sources,it has strong antioxidant activity, and has high value to research.This study examined the chemical composition and antiodant activity of 29 propolis samples from 20 provinces of China.E1%Spectrophotometry was used to determine the color intensity, the specific absorbance(1cm) and the content of total phenol, total flavonoids, flavone-flanonol, and flavanone.Reversed phase-high performance liquid chromatography (RP-HPLC) was used to determine the concent of 23polyphenolic components, and ferric reducing antioxidant power for total antioxidant activity,1,1-diphenyl-2-picrylhydrazyl (DPPH) assay for antiradical activity.
