Propolis is a viscous substance produced and collected from plant shoots or exudates by worker bees. This study aimed to identify phenolic compounds, carotenoids, volatile compounds, and antiradical activity of propolis obtained from two stingless bees (SB), Scaptotrigona bipunctata (Tubuna) and Scaptotrigona depilis (Canudo), all native from Rio Grande do Sul. The two propolis showed a similar qualitative composition, but with quantitative differences. Catechin was the major phenolic compound found in propolis from S. bipuncata and S. depilis. The propolis from S. depilis showed a higher concentration of carotenoids, mainly lutein. The α-pinene was the volatile compound found in greater concentration in the two propolis.
