Bottom Line: This material, as well as the secretions of 20 plant species that are often mentioned as its probable botanical source, have been investigated by RP-HPTLC.The propolis and plant resin showed high relative percentages of the isoflavonoids 3-Hydroxy-8,9-dimethoxypterocarpan and medicarpin.To our knowledge this is the first report of the secretion of a leguminous species being the source of propolis.

ABSTRACT
Red propolis is a new type of Brazilian propolis. This material, as well as the secretions of 20 plant species that are often mentioned as its probable botanical source, have been investigated by RP-HPTLC. Phytochemical evidence based on UV-VIS spectra, RP-HPLC and GC-MS, showed Dalbergia ecastophyllum (L.) Taub. to be the main source of red propolis in Alagoas state. The propolis and plant resin showed high relative percentages of the isoflavonoids 3-Hydroxy-8,9-dimethoxypterocarpan and medicarpin. To our knowledge this is the first report of the secretion of a leguminous species being the source of propolis.

Mentions: The results of UV-VIS spectroscopy, HPLC (Fig. 1) and GC-MS (Table 1) demonstrated that the chemical profile of Dalbergia ecastophyllum was similar to the chemical profile of red propolis. According to GC-MS, the main constituents of both extracts are the isoflavononoids medicarpin and 3-Hydroxy-8,9-dimethoxypterocarpan, the latter representing more than 60% of the composition in both extracts (Table 1).Figure 1.
