Resumen: "The honey produced by the stingless bees Melipona beecheii and Trigona nigra, is traditionally being used in religious ceremonies and for healing. Its composition is determined by the floral origin and kind of bee. Our aim was to correlate the total content of phenolic compounds (PC) with the floral origin of the honey produced in Tenosique,Tabasco, Mexico. A total of four M. beecheii honey samples were analyzed: one from Miguel Hidalgo and three from San Marcos. Only one T. nigra honey sample was collected (San Marcos). Total PC was determined using Folin-Ciocalteu method and acetolysis method was followed for palynological analysis. Three honey samples from M. beecheii were translucent yellow, two of them showed dominance of Eugenia sp. and one sample registered abundant Lonchocarpus sp. pollen grains. Three pollen types with percentages = 10% were registered both in one of the M. beecheii samples, dark yellow, and in the T. nigra honey sample, dark amber. PC concentration was related to both the color of the honey and the variety of flowers visited. In general, honey samples with three taxa = 10% are darker and contain a greater proportion of phenolic components than those in which only one pollen type was abundant. Due to its richness in both floral species and bees, Tabasco has the potential to produce different types of honey that may be highly accepted in the market, since in general it is appropriate to make the floral origin known. When the honey is of monofloral origin, prices greatly increase."
