“…A synergistic effect of the nonpolar compounds in M. quadrifasciata propolis was also suggested as responsible for its antibacterial activity. The hexane (MIC = 62.5 mg/L) and dichloromethane (MIC = 125 mg/L) fractions presented the most promising antibacterial results against M. pneumoniae [77].…”

Propolis has been extensively studied and several chemical constituents, mainly flavonoids, terpenes and phenolics, have been identified. With the emerging microbial resistance to antibiotics, the interest in the search for active compounds, mainly secondary metabolites of plants, has been increasing significantly. In this chapter, we describe the characteristics of the main species of native stingless bees found in South America, especially in Brazil, the ancestral use of propolis produced by them, its chemical composition and its potential for the development of new therapeutic compounds. Its chemical composition is very rich, and for many bee species it remains to be unfolded. Its biological properties evaluated so far include the antibacterial, antimycoplasmic, antifungal, antiviral, antioxidant and anti-inflammatory activities, but not for all known bee species. However, their existence is threatened by the introduction of exotic bees in the environment or using pesticides that annually kill millions of individuals. As if that were not enough, we face the destruction of original forests themselves, and the reforestation strategies with exotic plants.

The biodiversity of Brazil provides an excellent climate and favorable pollination conditions for Apis mellifera L., especially in the Eastern Amazon region, which boasts vast floral wealth, including an abundance of açaí (Euterpe oleracea) flowers and fruits. In the present study, seven types of honey were evaluated: three containing floral nectar from açaí (Açaí honey) collected in the Eastern Amazon region (Açaí honey from Breu Branco (AH1 and AH2) and Açaí honey from Santa Maria (AH3), both from the state of Pará, Brazil) and four honeys from different regions of Brazil (Aroeira honey from Minas Gerais, Cipó-Uva honey from Distrito Federal, Mangue honey from Pará, and Timbó honey from Rio Grande do Sul). The characteristics of these honeys were evaluated by examining their physicochemical properties, melissopalynological aspects, color, antioxidant potential, and their constituent compounds, which were confirmed through GC-MS analysis. Açaí floral nectar honeys presented physicochemical results similar to those of other honeys, aligning with Brazilian legislation norms, but differed in their high values of free acidity, apparent sugars, and lower reducing sugars, which are directly related to their botanical origin. These differences correlate with unique flavor and distinct aroma characteristics. Melissopalynological analysis confirmed the botanical origin of the honeys containing açaí floral nectar, which had a color range from amber to dark amber. The three açaí honeys demonstrated high antioxidant capacity and superior flavonoid and polyphenol content compared to other honeys, particularly the açaí honey from Breu Branco (AH1), which had four times the content to combat free radicals compared to the honey with the highest potential (Aroeira honey). GC-MS analysis confirmed the presence of antioxidant properties as well as potential anti-inflammatory, antibacterial, antimicrobial, and antitumor capabilities in açaí honeys, which have not yet been fully studied.
