Objective: To screen α-amylase and α-glucosidase inhibitors from the different fractions of crude hydro-alcoholic extract of heartwood of Tecomella undulata Linn.

Methods: Four fractions of crude hydro-alcoholic extract of heartwood of plant were used for in-vitro inhibitory assays against digestive enzymes: α-amylase and α-glucosidase. For assay, different concentrations (20, 40, 60, 80, 100 µg/ml) were used for all fractions. Standard protocol was used for preliminary phytochemical screening of different bioactive components present in all fractions.

Results: The fractions have shown moderate to highest inhibitory activity against both enzymes. But, the strong inhibition was revealed by acetone fraction against α-amylase with very minimal inhibitory concentrations at IC50 values when compared with a standard drug acarbose. Several medicinally active phytocomponents such as flavanoids, saponin, anthraquinones, tannins, triterpenoids and phenols were observed in all studied fractions.

Conclusion: The different fractions prepared from crude hydro-alcoholic extract of heartwood of plant are capable of inhibiting α-amylase and α-glucosidase and it can be concluded that heartwood of Tecomella undulata Linn. is partially active against postprandial hyperglycemia, thus diabetes mellitus.

Keywords: Tecomella undulata Linn., Diabetes mellitus, α-Amylase, α-Glucosidase.
