Zusammenfassung:•Twenty-six phenolic compounds were found in stingless bee honeys.•Honey of stingless bees has remarkable antioxidant activity.•The minerals of stingless bee honey are highly bioaccessible.•Absence of heavy metals in stingless honey. 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 (8.02–94.8μg 100g1), p-coumaric acid (4.54–64.3μg 100g1), naringin (4.00–32.0μg 100g1) and taxifolin (12.0–1920μg 100g1). 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 (263–4980μgg1), followed by calcium (88.7–138μgg1), sodium (12.7–261μgg1) and magnesium (25.9–231μgg1). 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.
