Figure 2: Acute effects of GS extract on blood glucose of diabetic rats. GS extract (200 or 400 4or 600 mg/kg) or GB (5.0 mg/kg) or water was administered orally to overnight-fasted rats and blood glucose was measured at 0, 1, 2, and 3h after extract administration. Values are mean ± SEM (n=7). Db, diabetic rats treated with water only; Db+CS-200, Db+CS-400, Db+CS-7600, diabetic rats treated with 200, 400 and 600 mg/kg of GS extract, respectively. Db+GB, diabetic rats treated with glibenclamide. *P<0.05, **P<0.01, ***P<0.001, compared to their respective 0h values.
