New alpha-glucosidase inhibitors, CKD-711 and CKD-711a were produced from the fermentation broth of Streptomyces sp. CK-4416 which was isolated from a forest soil of Jeju Island, South Korea. CKD-711 and CKD-711a were purified by Dowex 50W-2X and Sephadex G-10 column chromatography. In in vitro studies, CKD-711 showed a potent inhibitory activity against a-glucosidase from mammalian, but less i...

The alpha-amylase is used extensively in many different industrial sectors and renowned for modifying starch by rupturing 1-4 glycosidic bands. Depending on the intrinsic properties of microorganism, several alpha-amylases with thermostable halotolerant are expressed. In current study, bacteria were isolated from Ergani Makam Mountain. Identification optimization performed. As a result 16S rRNA...

The aim of this study was production and partial purification of α-amylase enzyme by Bacillus licheniformis. B. Licheniformis was allowed to grow in broth culture for purpose of inducing α-amylase enzyme. Optimal conditions for amylase production by B. Licheniformis are incubation period of 120 h, temperature of 37 °C and pH 7.0. The α-amylase enzyme was purified by ion exchange chromatography ...

We hypothesized that some medicinal herbs and food plants commonly used in the management of diabetes can reduce glucose peaks by inhibiting key carbohydrate hydrolyzing enzymes. To this effect, extracts of Antidesma madagascariense (AM), Erythroxylum macrocarpum (EM), Pittosporum senacia (PS), and Faujasiopsis flexuosa (FF), Momordica charantia (MC), and Ocimum tenuiflorum (OT) were evaluated ...

Ten bacterial strains isolated from the soil samples in the presence of cyclohexane were screened for amylase production. Among them, culture RG-01 was adjudged as the best amylase producer and was identified as Bacillus tequilensis from MTCC, Chandigarh. The isolate showed maximum amylase production (8100 U/mL) in the presence of starch, peptone, and Ca(2+) ions at 55°C pH 7.0 within 24 h of i...

The purpose of this research was to investigate the inhibitory effect of jicama extract on α-glucosidase activity, α-amylase activity, and postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice. Jicama extract showed prominent inhibitory effects against α-glucosidase and α-amylase. The IC50 values of jicama extract against α-glucosidase and α-amylase were 0.083±0.004 and 0.091...

background and objectives: resistance towards reveling antibiotics has captured great interest in evaluating the antimicrobial properties of the natural plants. taraxacum mongolicum is widely used as a folklore medicinal plant for its diuretic, antirheumatic and anti-inflammatory properties. though there are some reports on antimicrobial properties of taraxacum mongolicum, studies on antibacter...

The aqueous extract of Triumfetta semitriloba is part of the Costa Rican folk pharmacopoeia. It shows no in-vitro inhibitory action on the hydrolytic activity of porcine pancreatic amylase, lipase or proteases, thus diminishing the concern of intestinal malabsorption in human beings.

The habitat of endophytic bacteria in plant tissues making it automatically used by plants to protect themselves against pathogenic bacteria. Endophytic have been applied various fields, including agriculture, pharmacy, medicine, and biotechnology. This review was carried out summarize recent studies focusing on the diversity derived from traditional medicinal which antibacterial activity extra...
