Abstract
Propolis is a honeybee product with various biological activities, including antidiabetic effects. We previously reported that artepillin C, a prenylated cinnamic acid derivative isolated from Brazilian green propolis, acts as a peroxisome proliferator-activated receptor γ (PPARγ) ligand and promotes adipocyte differentiation. In this study, we examined the effect of baccharin, another major component of Brazilian green propolis, on adipocyte differentiation. The treatment of mouse 3T3-L1 preadipocytes with baccharin resulted in increased lipid accumulation, cellular triglyceride levels, glycerol-3-phosphate dehydrogenase activity, and glucose uptake. The mRNA expression levels of PPARγ and its target genes were also increased by baccharin treatment. Furthermore, baccharin enhanced PPARγ-dependent luciferase activity, suggesting that baccharin promotes adipocyte differentiation via PPARγ activation. In diabetic ob/ob mice, intraperitoneal administration of 50 mg/kg baccharin significantly improved blood glucose levels. Our results suggest that baccharin has a hypoglycemic effect on glucose metabolic disorders, such as type 2 diabetes mellitus.
Highlights
Propolis is a sticky, resinous material that honeybees (Apis mellifera L.) collect from plants and mix with wax and other secretions to maintain hive temperatures and seal cracks in the hive [1]

Summary
Resinous material that honeybees (Apis mellifera L.) collect from plants and mix with wax and other secretions to maintain hive temperatures and seal cracks in the hive [1]. Propolis has a complex composition that includes beeswax, resin, and volatile compounds as main constituents [7]. The biological activity of propolis is attributed to plant-derived substances. Baccharis dracunculifolia is the main botanical source of Brazilian green propolis, which characteristically contains cinnamic acid derivatives, such as p-coumaric acid, baccharin, drupanin, and artepillin C [8,9]. The worldwide prevalence of type 2 diabetes is increasing annually [10,11].
