A thermostable and detergent-stable α-amylase from a newly isolated Anoxybacillus sp. AH1 was purified and characterized. Maximum enzyme production (1874.8 U/mL) was obtained at 24 h of incubation. The amylase was purified by using Sephadex G-75 gel filtration, after which an 18-fold increase in specific activity and a yield of 9% were achieved. The molecular mass of the purified enzyme was est...

The current objective of the study is to evaluate the α-amylase inhibitory activity of butein and tricetin using in silico docking studies. In this perspective, butein and tricetin ligands were prepared for the docking evaluation. Acarbose, a known α-amylase inhibitor was used as the standard. In silico docking studies were carried out using recent version of AutoDock 4.2, which has the basic p...

BACKGROUND Diabetes mellitus is one of the most common endocrinal disorders and medicinal plants continue to play an important role in the management of this disease. In this study, Rosa canina was investigated for the antioxidant and α-amylase inhibition activities. MATERIALS AND METHODS Methanolic extract of Rosa canina was investigated for its potential antioxidant activity. The extracts' ...

Persea americana fruit and leaves had been known in folk medicine for their anti-diabetic prowess. Therefore, this study sought to investigate the inhibitory effect of phenolic extract from avocado pear (Persea americana) leaves and fruits on some key enzymes linked to type 2 diabetes (α-amylase and α-glucosidase); and sodium nitroprusside (SNP) induced lipid peroxidation in rats' pancreas in v...

the carob moth is one of the most devastating pests of pomegranate and some other products. various pest control measures have been undertaken in order to control this pest but none of them has been successful so far. in the current study the effects of cereal seed proteinaceous extracts including triticale and three wheat cultivars (mv17, aflak, and zare) have been studied on α-amylase and pro...

Background. This study sought to investigate the antioxidant and antihyperglycemic properties of Musa sapientum (Latundan banana) (MSL), Musa acuminata (Cavendish banana) (MAC), and Musa acuminate (Red Dacca) (MAR). Materials and Methods. The sugar, starch, amylose, and amylopectin contents and glycemic index (GI) of the three banana cultivars were determined. Furthermore, total phenol and vita...

An extracellular α-amylase from the obligate halophilic Aspergillus penicillioides TISTR3639 strain was produced and enriched to apparent homogeneity by ammonium sulfate precipitation and Sephadex G100 gel filtration column chromatography. The mass of the purified amylase was estimated to be 42 kDa by SDS-PAGE. With soluble starch as the substrate it had a specific activity of 118.42 U · mg(-1)...

Objective: The purpose of this study is to isolate and characterize the andrographolide betulin from methanolic leaves extract Andrographis echioides also used evaluate alpha-amylase alpha-glucosidase inhibitory activity isolated compounds using in silico docking studies.
 Methods: isolation was done column chromatography gradient mobile phase. Structural elucidation carried out on basis s...

Betalains in Amaranthus tricolor leaf were identified by means of reversed phase high-performance liquid chromatography (HPLC) and Liquid chromatography-Mass spectrometry (LC-MS). In addition to the known compound red-violet amaranthin, two yellow pigments were detected in Amaranthus tricolor. A novel betaxanthin, methyl derivative of arginine betaxanthin was identified on the basis of UV-Vis s...

The present investigation was carried out to determine the nutritional and functional properties of T. cucumerina. Water extracts of freeze dried flowers, fruits, and leaves of T. cucumerina were evaluated for their total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity, α-amylase inhibitory activity, and fiber and mineral contents. Antioxidant activity, TPC, and TFC ...
