BACKGROUND Some Ficus species have been used in traditional African medicine in the treatment of diabetes. The antidiabetic potential of certain species has been confirmed in vivo but the mechanism of activity remains uncertain. The aim of this study was to determine the activity and to investigate the mechanism of antidiabetic activity of ten selected Ficus species through inhibition of α-amyl...

Staphylococcus aureus is one of the prominent Gram positive human pathogen secretes many surface and secretary proteins including various enzymes and pathogenic factors that favour the successful colonization and infection of host tissue. α-amylase is one of the enzymes secreted by S. aureus which catalyses the breakdown of complex sugars to monosaccharides, which are required for colonization ...

In the present study, selection of an appropriate volume and temperature for α-amylase production by Saccharomyces cerevisiae GCB-20 has been reported. The fermentation medium at the level of 15-40 ml was investigated in 250 ml conical flasks for enzyme production. Maximum α-amylase production (210 IU/ml/min) by S. cerevisiae GCB-20 was obtained in 25 ml of fermentation medium at 35°C. The kine...

Materials and Methods: Antidiabetic potential of GW was evaluated by assay of α-amylase and α-glucosidase inhibitory activity; haemoglobin glycosylation and yeast glucose uptake. The antioxidant potential of GW was assessed by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2′azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation decolorization assay and superoxide assay. The inh...

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...

BACKGROUND Cereal seed germination involves mobilization of storage reserves in the starchy endosperm to support seedling growth. In response to gibberellin produced by the embryo the aleurone layer synthesizes hydrolases that are secreted to the endosperm for degradation of storage products. In this study analysis of intracellular protein accumulation and release from barley aleurone layers is...

PURPOSE Recent reports suggest that the hypoglycaemic effects of the triterpenes involve inhibition of glucose transport in the small intestine. Therefore, the effects of Syzygium spp-derived triterpenes oleanolic acid (OA) and maslinic acid (MA) were evaluated on carbohydrate hydrolyzing enzymes in STZ-induced diabetic rats and consequences on postprandial hyperglycaemia after carbohydrate loa...

The objective of the present study was to determine the antilipidperoxidation and in vitro α-amylase and lipase inhibitory activity of the Boswellia ovalifoliolata Bal Henry (BOB) extract. The polyphenolic compounds, flavonoids, and tannins content of the extracts were estimated by spectrophotometry. Antioxidant activity on goat liver lipid peroxidation and linoleic acid was d...

BACKGROUND Fungal amylase, mainly constitute of fungal α-amylase and glucoamylase, are utilized in a broad range of industries, such as starch hydrolysis, food and brewing. Although various amylases have been found in fungi, the amylases from Aspergillus dominate the commercial application. One of main problems exist with regard to these commercial use of amylases is relatively low thermal and ...
