The chemical composition and antioxidant activity of mandaçaia geopropolis varies more due to region than month of collection.

Stingless bees are responsible for pollinating up to 90% of Brazilian flora, so their study is of commercial and ecological importance. Stingless bees mix plant resins with wax and soil, forming geopropolis. Studies of the variability in composition and activity due to species, place and season of collection are lacking.
