Effects of SE on biochemical markers associated with diabetes in db/db mice. Serum (a) TG and (b) TC levels. c Serum insulin and (d) HOMA-IR levels. Serum (e) SOD and (f) GPx levels. The data were presented as mean ± SD. N + : db/m +  + saline; NC: db/db + saline; PC: db/db + metformin; SE200: db/db + stevia extract 200 mg/kg BW; SE500: db/db + stevia extract 500 mg/kg BW; SV: db/db + stevioside 40 mg/kg BW. ^### p < 0.001 vs. N + ; ^*** p < 0.001, ^** p < 0.01, ^* p < 0.05 vs. NC
