Abstract:Objective
To  compare  the contents of baicalein and galangin in propolis of different origins.Methods The contents of baicalein and galangin in 13 kinds of prololis of different origins were determinated by high performance liquid chromatography (HPLC).The　samples were separeted by C18 cloumn with the mobile phase of methanol-0.15% phosphoric (60∶40) and methanol-0.15% phosphoric (65∶35),the wavelength of detection was  268 nm.Results  Five samples were collected in each  area.The contents of baicalein and galangin in propolis of Jilin Jiaohe and Henan Changge were higher,all  over　2.0% and 1.8%,and the former was higher than the later(P<0.05);compared with the other 11 areas,there were significant differences（P<0.05）.Conclusion The contents of baicalein and Galangin in propolis of Jilin Jiaohe and Henan Changge are higher.
