Bioactive compounds of propolis from Scaptotrigona bipunctata and Scaptotrigona depilis

This study aimed to identify bioactive compounds of propolis obtained from two stingless bees, S. bipunctata and S. depilis. Both propolis showed similar qualitative composition, but with quantitative differences. Propolis from S. bipunctata had a higher concentration of ferulic acid and propolis from S. depilis a higher concentration of p-coumaric acid. The propolis S. depilis proved to be rich in lutein. The α-pinene was the volatile compound found in greater concentration in both propolis.
