Maceió: SBQc2022  ap. 698.  aThe stingless bee Melipona mandacaia popularly known as mandacaia is endemic to the Caatinga biome, being found in the region of Vale do São Francisco. It is a very important bee for meliponiculture in the municipalities of Petrolina (PE) and Juazeiro (BA), where they are used for honey production. Due to its importance and endemism, the mandaçaia has been the subject of research, mainly due to the fact that there is little information about the species, together with the great demand for the rational creation and commercialization of its products. Profile of compounds by Ultra-Performance Liquid Chromatography coupled with a Diode Array Detector and quadrupole Time of Flight Mass Spectrometry MS/MS) of sixteen Melipona mandacaia honeys from semiarid region of the Northeast of Brazil are presented. The melissopalynological analysis showed one principal pollen types of Mimosa tenuiflora (jurema preta). Mandaçaia monofloral honeys have similar characteristic profile of phenolic compounds. Fifty-three compounds were identified, mainly phenolic derivatives. Forty aglycone flavonoids: 26 flavones/flavonols and 14 flavanones/flavanonols.  aBee pollen  aChemical analysis  aMelipona  aAbelha  aAnálise Química  aCaatinga  aMel  aAbelha sem ferrão  aBioma Caatinga  aMel de Mandaçaia  aMeliponicultura1 aF.
