CHEMICAL PROFILING OF SIX SAMPLES OF BRAZILIAN PROPOLIS

Six samples of Brazilian propolis from Minas Gerais and Parana states were analyzed to identify the constituents (GC/MS and HPLC/MS) and to determine their contents (HPLC and external standardization). All samples contained characteristic constituents of green propolis, but the samples from Minas Gerais had higher contents of prenylated phenylpropanoids and caffeoylquinic acids. Kaempferide and two other flavonoids were among the major constituents of the samples from Minas Gerais. Luteolin 5-O-methyl ether was detected only in samples from Parana. Baccharis dracunculifolia was a source of resins for all samples analyzed, but the samples from Parana had more complex plant origin.
