Taraxacum officinale F.H. Wigg (Asteraceae) root is traditionally used to treat diabetes, dyspepsia, heartburn, anorexia and hepatitis. In this work, petroleum ether, chloroform, methanol and aqueous extracts of T. officinale root were evaluated for their antidiabetic activity in normoglycemic and alloxan-induced diabetic mice at two concentrations (200 and 400 mg/kg) using antidiabetic and subcutaneous glucose tolerance tests. Herein, in vitro glucose uptake assay was performed using HepG2 and 2-NDBG, while LC-MS/MS was employed for the phytochemical study of the main active constituents in the active extract. In the experiments, T. officinale root aqueous extract (400 mg/kg) showed a significant decrement in blood glucose level (62.33%, p ≤0.05), while other extracts (p >0.05) showed insignificant activity – in alloxan-induced diabetic mice with no apparent effect on the normoglycemic model.
