Antioxidant Activity of a Geopropolis from Northeast Brazil: Chemical Characterization and Likely Botanical Origin

Figure 1

HPLC chromatogram of ethanol extracts of geopropolis of Scaptotrigona postica (“mandaguari”; Meliponini) from the meliponary at the University of Mossoró (state of Rio Grande do Norte, northeast Brazil), as characterized by HPLC-DAD. Digits of the chromatogram peaks correspond to the numbers seen in Table 2, used to indicate compounds characterized by HPLC-DAD-MS/MS.
