 note = {The number of obesity and type 2 diabetes mellitus（T2DM）patients is increasing worldwide. T2DM ischaracterized by the decreasing of insulin sensitivity and insufficient insulin release from pancreatic β-cells caused by insulin resistance. in addition, impaired adipocyte differentiation enhances insulin resistance. as the peroxisome proliferator-activated receptorγ（PParγ）plays an important role in insulin sensitivity and adipocyte differentiation, the thiazolidine drugs which are known to PParγagonist can clinically improve insulin resistance. Persicaria tinctoria has been used as a dye and traditional Japanese medicine in Japan over the years. Tryptanthrin, which is an ingredient of this plant is reported to have a variety of bioactivity such as antibacterial, anti-cancer, and anti-inflammatory. recently, Persicaria tinctoria is also used as edible food, and its usefulness has attracted attention. Thus, to investigate the effect of tryptanthrin on the cell differentiation and adipogenesis process in 3T3-L1 cells, 3T3-L1 cells were cultured to determine the effect of cell differentiation and glucose uptake with tryptanthrin. as a result, tryptanthrin enhanced adipocyte differentiation in 3T3-L1 cells similar to rosiglitazone. This effect was inhibited by cotreatment with GW9662, a PParγ antagonist. in mature 3T3-L1 adipocytes, the lipid droplet size and accumulation were reduced by this compound and observed micro lipid droplets. The glucoseconsumption were also significantly increased. in conclusion, this finding suggested that tryptanthrin is a potential anti-diabetic compound for T2DM by promoting adipocyte differentiation and glucose consumption via PPAR γ.},
