Resumo:  ABSTRACT Leishmaniasis is a parasitic disease caused by protozoa of the Leishmania genus. It may manifest in visceral and tegumentary forms, and pentavalent antimonials are the first choice drugs used for the treatment. Frequently these drugs show low efficiency and high toxicity to mammalian host. The present study describes the chemical profile and the in vitro leishmanicidal effects of red propolis and Dalbergia ecastaphyllum extracts from Sergipe, Brazil, in Leishmania chagasi and Leishmania amazonensis promastigotes. The phenolic composition of the extracts was evaluated by direct infusion electrospray ionization mass spectrometry (ESI-MS) fingerprinting. The leishmanicidal effect was evaluated by the Resazurin colorimetric method. Similar composition profiles have been found for D. ecastaphyllum and propolis samples. The isoflavones formononetin, biochanin A, daidzein and pinocembrin were identified in both extracts. Propolis extract showed leishmanicidal activity in both L. chagasi and L. amazonensis, with IC50 values of 21.54 and 9.73 µg/mL, respectively. The D. ecastaphyllum extract presented activity only in L. amazonensis, with IC50 of 53.42 µg/mL. These results suggest that red propolis extract from Sergipe has the leguminosae D. ecastaphyllum as botanical origin, and that it presents potential leishmanicidal activity, which may be associated with the presence of the phenolic compounds found in its composition.
