摘要

The chemical profiles of honey vary depending on floral sources and bee species origin. These variations may influence honey quality and therapeutic potential. This study evaluated the physicochemical and antioxidant properties of honey samples from three stingless bee species in the genus Hypotrigona: H. gribodoi, H. ruspolii and H. araujoi. Our findings show that honey composition was influenced by bee species, whereby H. ruspolii honey demonstrated a distinct chemical profile compared to H. gribodoi and H. araujoi. Principal component analysis (PCA) revealed that honeys from the three Hypotrigona species can be discriminated based on the levels of moisture content, acidity, total dissolved solids and monosaccharide sugars. All honey samples met the acceptable levels of moisture content (18.92–26.02%), free acidity (19.24–53.87 meq/Kg), sucrose (0.28–1.6 g/100 g), ash content (0.1–0.5%) and hydroxymethylfurfural (1.27–21.38 mg/Kg) stipulated in the existing stingless bee honey quality standards of Tanzania and the East African Community. Additionally, Hypotrigona honey displayed appreciable levels of total flavonoid content (39.55–45.96 mg QE/100 g), total phenolic content (70.97–75.03 mg GAE/100 g), and radical scavenging activity (54.13–56.89%), indicating antioxidant potential. This study contributes to the scant knowledge of honeys produced by Afrotropical stingless bees, particularly from the genus Hypotrigona, which is among the least studied.
