The phenolic composition, antioxidant capacity and bioaccessibility of the minerals of thirteen honey samples from nine different species of stingless bees (Meliponinae) were determined in this study. Twenty-six phenolic compounds were found. The major phenolic compounds were salicylic acid (8.02-94.8 mu g 100 g(1)), p-coumaric acid (4.54-64.3 mu g 100 g(1)), naringin (4.00-32.0 mu g 100 g(1)) and taxifolin (12.0-1920 mu g 100 g(1)). Moreover, the presence of mandelic acid, caffeic acid, chlorogenic acid, rosmarinic acid, aromadendrin, isoquercetrin, eriodictyol, vanillin, umbelliferone, syringaldehyde, sinapaldehyde and carnosol in stingless bee honeys was reported for the first time. The study also states that the abundant minerals in the samples were potassium (263-4980 mu g g(1)), followed by calcium (88.7-138 mu g g(1)), sodium (12.7-261 mu g g(1)) and magnesium (25.9-231 mu g g(1)). The estimation of the minerals bioaccessibility demonstrated high fractions (73.62-107.6% of the total concentrations). Stingless bee honey has considerable concentrations of phenolic compounds and macro minerals (K, Ca, Na and Mg) as well as a related antioxidant capacity, suggesting a source of natural antioxidants.
