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...

Recently, we reported a novel congenital disorder of glycosylation (CDG-IIb) caused by severe deficiency of the glucosidase I. The enzyme cleaves the alpha1,2-glucose residue from the asparagine-linked Glc(3)-Man(9)-GlcNAc(2) precursor, which is crucial for oligosaccharide maturation. The patient suffering from this disease was compound-heterozygous for two mutations in the glucosidase I gene, ...

The purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. The levels of phenolic constituents in these medicinal plants were also quantified and compared. Antioxidation potentials were determined colorimetrically for scavenging activities against DPPH and NO radicals. Metal chelating assay was based on the mea...

Background: In Nigeria, the leaves of Manihot esculenta (Crantz) are eaten as vegetables. The leaves are rich in phytochemicals, valuable and natural sources of antioxidants, and are highly useful for human health and disease prevention. This study was aimed to evaluate the in vitro inhibitory effects of two extracts derived from the plant leaves on α-glucosidase and α-amylase. The total flavon...

The present study was to evaluate the anti-diabetic activity of the aqueous extract of Actinidia kolomikta root against baker's yeast α-glucosidase and rat intestinal α-glucosidase. As a result, the aqueous extract of Actinidia kolomikta root exhibited excellent baker's yeast α-glucosidase inhibitory activity which was better than acarbose. It also showed rat intestinal α-glucosidase inhibitory...

N sweetclover (Melilotus alba Desr.) the allelic pair designated B/b was I originally thought to be concerned with coumarin biosynthesis. Extracts of BB plants were reported to contain substantial amounts of both free and bound coumarin, while extracts of bb plants contained only bound coumarin (GOPLEN. GREENSHIELDS and BAENZIGER 1957; HASKINS and GORZ 1957), more recently identified as coumari...

A soil microorganism producing αand β-glucosidase inhibitors was identified as Bacillus lentimorbus, based on the fatty acid and morphological analyses, along with biochemical and physiological tests. The α-glucosidase inhibitor was highly produced by this strain in a culture medium containing 0.25% of sodium glutamate and 0.5% of glucose, pH 8.0 at 30C for 2 days. The α-glucosidase inhibitor f...

the purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. the levels of phenolic constituents in these medicinal plants were also quantified and compared. antioxidation potentials were determined colorimetrically for scavenging activities against dpph and no radicals. metal chelating assay was based on the mea...

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 o...
