deoxynojirimycin/morus

1-Deoxynojirimycin (DNJ), the main hypoglycemic constituent in mulberry (Morus alba) latex, has been extensively researched. Although there is considerable interest in the biological effects of DNJ, the roles of 1-deoxynojirimycin (DNJ) in glycometabolism and energy metabolism in insects have

Folium mori ( Sāng Yè, leaf of Morus alba L.; FM) is known to possess hypoglycemic effects, and 1-deoxynojirimycin (1-DNJ) has been proposed as an important functional compound in FM. However, the hypoglycemic activity of purified 1-DNJ has been rarely studied. It is also not known how FM and 1-DNJ

A rapid, reliable and suitable method for the determination of 1-deoxynojirimycin (DNJ) in Morus alba L. leaves has been developed. The DNJ in 100 mg dried leaves was extracted twice with 10 mL aqueous 0.05 mol/L HCl, then derivatized by 6-aminoquinoiyi-N-hydroxysuccinimidyl carbamate (AQC) in K3BO3

A simple and rapid method for determining 1-deoxynojirimycin (DNJ), a potent glucosidase inhibitor present in mulberry leaves (Morus alba and Morus bombysis), by high performance liquid chromatography coupled to an evaporative light scattering detector (ELSD) has been developed. DNJ was separated

A novel HPLC-MS/MS method was developed for the quantitative determination of 1-deoxynojirimycin (DNJ), a potent glucosidase inhibitor present in mulberry leaves (Morus alba L.). DNJ was isolated from the mulberry leave extract on a TSKgel Amide-80 column using a mixture of 0.1% formic acid and

In the present study, the extraction technology and preparative separation of 1-deoxynojirimycin from mulberry leaves were systematically investigated. Four extraction parameters (ethanol concentration, extraction temperature, extraction time and ratio of solvent to sample) were explored by response

A new method based on a Direct Analysis in Real Time (DART) ionization source coupled with triple quadrupole tandem mass spectrometry has been developed for rapid qualitative and quantitative analyses of 1-deoxynojirimycin (DNJ) in mulberry leaves. Two ions produced from DNJ, [M+H](+) (m/z 164) and

Aims/Introduction: The glucose analogue, 1-deoxynojirimycin (DNJ), found in mulberry (Morus alba) leaves, is a promising α-glucosidase inhibitor. We evaluated the effect of the ingestion of mulberry leaf extract with enriched DNJ content on postprandial hyperglycemia in subjects with impaired

Mulberry (Morus alba L.) represents one of the most commonly utilized plants in traditional medicine and as a nutritional plant used worldwide. The polyhydroxylated alkaloid 1-deoxynojirimycin (DNJ) is the major bioactive compounds of mulberry in treating diabetes. However, the DNJ content in

OBJECTIVE The present study focused on isolation, characterization and evaluation of purified compounds from Morus alba against Streptococcus mutans biofilm formation. METHODS The effect of crude extract from M. alba leaves was evaluated against oral pathogens, chiefly S. mutans. MICs were

A simple and rapid method for determining 1-deoxynojirimycin (DNJ), a potent glucosidase inihibitor present in mulberry leaves (Morus alba and Morus bombysis), by high-performance liquid chromatography coupled to an evaporative light scattering detector (ELSD) has been developed. DNJ was separated

The relationship between 1-deoxynojirimycin (DNJ) content and alpha-glucosidase inhibitory activity in mulberry (Morus) leaves is discussed. Mulberry leaves were collected from the Center for Bioresource Field Science, Kyoto Institute of Technology, Kyoto, Japan on 19 May, 9 July, and 9 August,

A rapid and reliable method suitable for assays of a large number of Morus alba leaves for 1-deoxynojirimycin (DNJ) has been developed. DNJ in 0.1 g of freeze-dried leaves was double-extracted in 10 mL of aqueous 0.05 M HCl by vortexing for 15 s at room temperature, derivatized with

A silkworm (Bombyx mori L.) extract known to contain naturally occurring iminosugars, including 1-deoxynojirimycin (1-DNJ) derived from the mulberry tree (Morus alba L.), was evaluated in surrogate HCV and HBV in vitro assays. Antiviral activity of the silkworm extract and one of its purified
