In this study, we investigated whether Sargassum yezoense extract (SYE) could inhibit α-glucosidase and α-amylase activities, and alleviate postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice. Freeze-dried S. yezoense was extracted with 80% ethanol and concentrated for use in this study. The hypoglycemic effect was determined by evaluating the inhibitory activities of SYE a...

Inhibition of α-amylase is an important strategy to control post-prandial hyperglycemia. The present study on Ruellia tuberosa, known as traditional anti-diabetic agent, is being provided in silico study to identify compounds inhibiting α-amylase in rat and human. Compounds were explored from PubChem database. Molecular docking was studied using the autodock4. The interactions were further visu...

Alpha-amylase inhibitor protein, which inhibits the activity of insect (Callosobruchus analis) α-amylase, was characterized from V. sublobata. The molecular weight of purified inhibitor protein was 14 kDa by SDS-PAGE. The inhibitor is non-glycosylated protein and its N-terminal sequence is similar (A P S P V...) to Phaseolus vulgaris α-AI-1. Its pI value is 6.0 and largely localised in cotyledo...

Diabetes mellitus is a multifactorial metabolic disease characterized by post-prandial hyperglycemia (PPHG). α-amylase and α-glucosidase inhibitors aim to explore novel therapeutic agents. Herein we report the promises of Dioscorea bulbifera and its bioactive principle, diosgenin as novel α-amylase and α-glucosidase inhibitor. Among petroleum ether, ethyl acetate, methanol and 70% ethanol (v/v)...

This study evaluated the in vitro antioxidative activity of Khaya senegalensis extracts and inhibitory effects of some solvent fractions on α-glucosidase and α-amylase activities. The stem bark, root and leaf samples of the plant were sequentially extracted with ethyl acetate, ethanol and water and then tested for antioxidative activity. Our findings revealed that the ethanolic extract of the r...

The management of postprandial hyperglycemia is an important strategy in the control of diabetes mellitus and complications associated with the disease, especially in the diabetes type 2. Therefore, inhibitors of carbohydrate hydrolyzing enzymes can be useful in the treatment of diabetes and medicinal plants can offer an attractive strategy for the purpose. Vaccinium arctostaphylos leaves are c...

Aqueous extracts of four seaweeds collected from Gulf of Mannar coastal waters were tested for α-amylase and α-glucosidase inhibition properties. The aqueous extracts of seaweeds in the order of Gracilaria edulis, Sargassum polycystum, Ulva lactuca and Gracilaria corticata showed significant inhibitory activity against α-amylase and α-glucosidase enzymes. G. edulis was found to be a potent inhi...
