Abstract(s)
This study assessed the polyphenolic profile and the antioxidant and antibacterial activities ofmonofloral honeys
produced by Meliponini in the Brazilian semiarid region. Honeys from Ziziphus joazeiro Mart. (juazeiro) and
Croton heliotropiifolius Kunth (velame branco) showed the highest total phenolic contents (TPCs) and the
greatest antioxidant activity in assays with DPPH and ABTS•+ radicals. Honeys from Mimosa quadrivalvis L.
(malícia) presented the strongest anti-peroxyl activity in ORAC assay. Juazeiro honeys showed the highest quantities
of trans-cinnamic, p-coumaric, ellagic and ferulic acids, as well as of catechin, rutin, hesperetin and chrysin
when compared to the other honeys produced by the same bee species. Malícia honeys showed the greatest
quantities of myricetin, quercetin and kaempferol among the studied honeys. Honeys with the highest TPCs presented
the highest antimicrobial activity. The results showed the impact of the floral source on the polyphenolic
profile as well as on the antioxidant and antimicrobial properties of Meliponini honeys.
