Abstract
The primary goal of this research is to examine the α-amylase inhibitory effect of phytoconstituents found in the roots of the Cyclea peltata plant. The extract will also be used to investigate the effect of root extract on α-amylase inhibition assay. The roots were gathered, processed, and extracted in petroleum ether before being kept at 4ºC. The extract was exposed to a preliminary phytochemical examination. The extract was employed in the α-amylase inhibition experiment at concentrations of 50, 100, 200, 400, 600, 800, and 1000 µg/ml with acarbose as a control. Molecular docking analysis was performed on the phytoconstituents cycleapeltine, cycleadrine, cycleacurine, cycleanorine, cycleahomine chloride, and acarbose on human pancreatic alpha-amylase 1B2Y. A preliminary phytochemical study revealed the presence of alkaloids, saponins, and terpenoids. The tests came back negative for flavonoids, steroids, and tannin. The root extract inhibited α-amylase at 69.42 ± 0.74 % at 1000 µg/ml and acarbose at 94.63 ± 0.57 %. The IC50 value was calculated and found to be 484.08 µg/ml for the extract and 42.47 µg/ml. The docking studies, revealed that cycleacurine (-4.751 Kcal/mol) has a comparable anti-diabetic effect to Acarbose (-6.713 Kcal/mol). Furthermore, the function groups –OH and –NH found in phytoconstituents interacted with the active site of 1B2Y similarly to acarbose. This provides evidence that the function groups –OH and –NH present in the phytoconstituents might inhibit alpha amylase.
