We found that Brazilian propolis (I,II) and the propolis of other countries [Chinese (III), Japanese(IV), Australian(V), New Zealand, Hungarian, Bulugalian, Ukrainian, Uzbekistanian, Uruguayan (VI), American (VII) and South African (VIII)] could bedistinguishedfrom each other by 3D-HPLC analysis. Brazilian propolis were cinnamic acid derivative type containing drupanin, artepillin C,(E)-3-prenyl-4-(2,3-dihydrocinnamoyloxycinnamic acid, (E)-3-(2,2-dimethyl-8-prenyl-2H-benzopyran-6-yl)-2-propenoic acid as the main constituents,whereas, the propolis of other countries are flavonoid type containing pinobanksin, chrysin, pinocembrin, galangin and pinobanksin-3-acetetae as the main constituents. The above results suggest that they are useful markers for the identification of the place of production of propolis. The 3D-HPLC analysis may be a effective method not only for the detection of flavonoids and cinnamic acid derivatives but also for chemical evaluation of propolis.
