AbstractLiquid chromatography mass-spectrometry (LC-MS) analysis of Brazilian propolis and the leaves, buds, stem and flowers of Baccharis dracunculifolia were performed. The water extracts of propolis and B. dracunculifolia both contain 3,4-di-O-caffeoylquinic acid (28), 3,5-di-O-caffeoylquinic acid (31) and chlorogenic acid (32). The intensities of 28 and 31 in the water extract of the buds were stronger than the other parts, suggesting that the buds of B. dracunculifolia should be potent source of these caffeoylquinic acids. Moreover, 27 individual compounds including labdane-type diterpenes, prenylated compounds, flavonoids and other phenolics which were previously isolated from Brazilian propolis, were also identified in the MeOH extract of B. dracunculifolia. Among them, 24 compounds were detected in the buds alone, indicating that it should be an important source of Brazilian propolis. The botanical origin of 19 components of Brazilian propolis was, for the first time, established to be B. dracunculifolia.
