To identify the plant origin of Brazilian propolis directly, we observed the behavior of honeybees in Minas Gerais State of Brazil. Honeybee workers bit and chewed leaves of the plant, Baccharis dracunculifolia, packed the material into their pollen basket, brought it back to their nest, and used it as propolis. We collected the leaves of B. dracunculifolia and propolis, and compared their constituents by liquid chromatography-mass spectrometry (LC/MS) analysis. There was no difference between the chemical constituents of the ethanol extracts of B. dracunculifolia and those of propolis. This indicates directly that the plant origin of Brazilian propolis is B. dracunculifolia.
为了直接确定巴西蜂胶的植物来源，我们观察了巴西米纳斯吉拉斯州蜜蜂的行为。工蜂叮咬并咀嚼了植物巴西酒神菊的叶子，将材料装入花粉篮，带回蜂巢，并将其用作蜂胶。我们收集了巴西酒神菊的叶子和蜂胶，并通过液相色谱 - 质谱联用（LC/MS）分析比较了它们的成分。巴西酒神菊乙醇提取物的化学成分与蜂胶的化学成分之间没有差异。这直接表明巴西蜂胶的植物来源是巴西酒神菊。
