Background: The Chenopodium album L. commonly recognized as Bathua, is widely distributed globally and contains various phytoconstituents that help treat several diseases. However, until now, aerial parts{\textquoteright} antidiabetic potential and the plant{\textquoteright}s acute toxicity at fraction level have never been established. Objectives: To investigate the acute toxicity, the in-vitro, in-vivo antidiabetic potential of the plant at fraction level. Materials and Methods: The aerial parts of the plant were fractionated into different fractions, i.e., flavonoid fraction (CAFF), tannin fraction (CATF), alkaloid fraction (CAAF), saponin fraction (CASF), and were analyzed for in-vitro alpha-amylase inhibition assay. The CAFF, CATF, and CAAF were selected based on in-vitro alpha-amylase inhibition assay results and were further screened for its acute toxicity and in vivo antidiabetic activity using a high-fat diet and streptozotocin-induced diabetes model. The CAFF was characterized by LC-MS, and a molecular docking study was carried out. Results: The in-vitro alpha-amylase inhibition assay revealed that CAFF was found to be more potent than standard Acarbose having IC50 values 122.18 {\textpm} 1.15 and 812.83{\textpm} 1.07 μg/ml, respectively. The CAFF fraction was found to possess potent antidiabetic activity in a dose-dependent manner in both in vitro and in vivo diabetic models and did not produce any sign of severe toxicity. Furthermore, the bioactive CAFF fraction was characterized by LC-MS, showed the presence of quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-O-rhamnosyl) glucoside (QRG) or quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-Orhamnosyl) galactoside (QRGa) and quercetin 3-O-rutinoside (rutin) (QR). It is predicted from the molecular docking study that the CAFF fraction primarily acts as an alphaamylase inhibitor. Conclusion: The CAFF fraction was found to poses dose-dependent potent antidiabetic activity and did not produce any sign of severe toxicity and primarily act as an alpha-amylase inhibitor.
