the imported willow leaf beetle, plagiodera versicolora is one of the main pests of forest trees worldwide including iran. activities of α- and β-glucosidases in the midgut of p. versicolora adults were studied in this research. the results showed a higher α- glucosidase activity of adultsthan β-glucosidase. the optimal phs for α- and β-glucosidases activities were found to be 6 and 9, respecti...

introduction: α-amylase is a major form of amylase found in humans and other mammals. it is the special key enzyme involved in carbohydrates breakdown. inhibition of this enzyme could be used in treatment of diabetes. in this study, the effect of ten iranian macrolichens on alpha amylase were tested. methods: different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated with enz...

objective(s):ethnopharmacological field surveys demonstrated that many plants, such as gentiana olivieri, helichrysum graveolens, helichrysum plicatum ssp. plicatum, juniperus oxycedrus ssp. oxycedrus, juniperus  communis var. saxatilis, viscum album (ssp. album, ssp. austriacum), are used as traditional medicine for diabetes in different regions of anatolia. the present study was designed to e...

the side effects associated with the usage of synthetic antidiabetic drugs make it imperative to search for alternative drugs from medicinal plants. therefore, this study was aimed at evaluating the α-amylase and α-glucosidase inhibitory potential of calotropis procera leaf, as well as its possible mode of inhibiting these enzymes. acetone, aqueous and ethanolic extracts of c. procera leaf was ...

in an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (pocl3). the synthesized compounds were identified by 1h-nmr, 13c-nmr, ft-ir spectroscopic techniques and elemental analysis. all products were...

Therefore, this study was aimed at evaluating the α-amylase and α-glucosidase inhibitory potential of Calotropis procera leaf, as well as its possible mode of inhibiting these enzymes. Acetone, aqueous and ethanolic extracts of C. procera leaf was ...

background: diabetes mellitus is a chronic disease. decreasing postprandial hyperglycemia by retarding glucose absorption through inhibiting carbohydrates digesting enzymes (α-amylase and α-glucosidase) is one of many approaches used for the management of this disease. this study was aimed at evaluating the normoglycaemic potential of helianthus annuus leaf. methods: the effect of the in vitro ...

the effects of allium sativum on yogurt formation and subsequent storage (4°c, up to 28 days) on proteolysis, microbial activity, and inhibition of α-amylase, α-glucosidase and angiotensin-i converting enzymes were investigated in vitro. allium sativum yogurt showed higher rates of ph reduction and increment of titrable acid than control during the incubation at 41°c. highest proteolysis was ob...

it is believed that the inhibition of carbohydrate hydrolyzing enzymes including α-amylase and α-glucosidase is one of the therapeutic approaches to decrease the postprandial glucose level after a meal, especially in the people with type 2 diabetes. medicinal plants and their extracts are one of the main sources to find new inhibitors to the enzymes. in our study four flavonoids, namely luteoli...
