Anti-diabetic and anti-urease inhibition potential of Amomum dealbatum Roxb. seeds through a bioassay-guided approach.

Using HPLC-PDA and HRMS analysis, five compounds p -coumaric acid, sinapic acid, quercetin, trans -ferulic and gallic acid were identified in seeds of Amomum dealbatum Roxb. The GC-MS analysis identified 1-dodecanol, phenol, 3,5-bis(1,1-dimethylethyl), Oleic Acid and 1-Heptacosanol which possess anti-diabetic properpties. A bioassay-guided technique was used to determine the degree of inhibition that A. dealbatum seeds crude methanol extract and its most active sub-fraction had against the α-glucosidase and Helicobacter pylori urease enzymes. In the Rat L6 myoblast cell line, glucose absorption through the GLUT4 transporter of most active subfraction (EASF80) was examined. According to a molecular docking investigation, these compounds strongly interacted with the GLUT4 transporter, H pylori and α-glucosidase enzyme. Sinapic acid interacted most strongly with the H. pylori urease enzyme while gallic acid interacted with both the α-glucosidase enzyme and the GLUT4 transporter. Additionally, a molecular docking simulation study was carried out to recognise the stability of the complexes.
