Objective. To study the effect of different proportions of Huangqi (Radix Astragali Mongolici) and Honghua (Flos Carthami) injection on α-glucosidase and α-amylase activity simultaneously. Methods. The injections were prepared according to the standards of the China Food and Drug Administration. The assay for potential α-glucosidase inhibitors was based on the hydrolysis of 4-methylumbelliferyl...

biochemical characteristics of α-amylase in the digestive system and head glands of cryptolaemus montrouzieri, a key predator of citrus mealybug, planococcus citri (pseudococcidae), were studied. the major isoform of α-amylase with the same molecular weight was detected in both gut and head glands loaded on polyacrylamide-starch gel electrophoresis. moreover, a minor band with much lower intens...

Chen, Z.-Y., Brown, R. L., Russin, J. S., Lax, A. R., and Cleveland, T. E. 1999. A corn trypsin inhibitor with antifungal activity inhibits Aspergillus flavus α-amylase. Phytopathology 89:902-907. In this study, we found that the inhibition of fungal growth in potato dextrose broth (PDB) medium by the 14-kDa corn trypsin inhibitor (TI) protein, previously found to be associated with host resist...

Diabetes is a metabolic disorder affecting about 220 million people worldwide. One of the most critical complications of diabetes is post-prandial hyper-glycemia (PPHG). Glucosidase inhibitor and α-amylase inhibitors are class of compounds that help in managing PPHG. Low-cost herbal treatment is recommended due to their lesser side effect for treatment of diabetes. Two plants with significant t...

In maltose syrup production, one of the critical processing stages is starch conversion process. During this process, reaction time and enzyme concentrations are two important parameters to obtain standard sugar spectrum. The purpose study is; i) find optimum during ii) determine process control dynamic in production. different amounts beta alpha-amylase enzymes (0.10, 0.15, 0.20 0.25 ml β-amyl...

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 ...
