fagomine/morus

D-Fagomine is an iminosugar first found in buckwheat (Fagopyrum esculentum Moench) which if used as a dietary supplement or functional food component may reduce the risks of developing insulin resistance, becoming overweight and suffering from an excess of potentially pathogenic bacteria. As

The mechanisms of potentiation by fagomine, an N-containing pseudo-sugar derived from mulberry leaves, of insulin secretion from isolated rat pancreatic islets in response to glucose was studied. Fagomine at more than 1 mmol/L significantly potentiated insulin secretion induced by 10 mmol/L glucose.

The aqueous MeOH extract of the leaves and root of Xanthocercis zambesiaca (Leguminosae) and eight structurally related nitrogen-containing sugars, fagomine (1), 4-O-beta-D-glucopyranosylfagomine (2), 3-O-beta-D-glucopyranosylfagomine (3), 3-epifagomine (4), 2,5-dideoxy-2,5-imino-D-mannitol (5),

OBJECTIVE To find out dynamic changes of flavonoids and alkaloids in Morus alba leaves by analyzing influence of different drying method and drying degrees, in order to provide evidence for quality evaluation of Morus alba leaves. METHODS Different drying methods, programmed temperature methods and

OBJECTIVE To study the chemical constituents from the leaves of Morus multicaulis. METHODS The compounds were isolated by ion exchange resin, silica gel and Sephadex LH -20 column chromatographies. Their structures were elucidated on the basis of physico-chemical properties and spectral

OBJECTIVE To study the chemical constituents from the root barks of Morus atropurpurea. METHODS The chemical constituents from the 70% ethanol extract of M. atropurpurea were isolated and purified by column chromatographic methods. Their structures were identified by physico-chemical properties as

The effects of hot water extracts and six compounds of N-containing sugars, 1-deoxynojirimycin (DNJ), N-methyl-DNJ (N-Me-DNJ), 2-O-alpha-D-galactopyranosyl-DNJ (GAL-DNJ), fagomine, 1,4-dideoxy-1,4-imino-D-arabinitol (DAB), and 1,2 alpha,3 beta,4 alpha-tetrahydroxynortropane (calystegin B2), derived

Mulberry leaves contain iminosugars, such as 1-deoxynojirimycin (1-DNJ), fagomine, and 2-O-α-D-galactopyranosyl deoxynojirimycin (GAL-DNJ) that inhibit α-glucosidase. In this study, we quantified iminosugars in Morus australis leaves and made the kinetic analysis in the hydrolysis of

It is known that 1-deoxynojirimycin (1) is contained in the leaves and roots of Morus sp. The modified purification procedures of 1 from leaves of Morus bombycis led to the isolation of many polyhydroxylated alkaloids. These include 1, N-methyl-1-deoxynojirimycin (2),

The leaves of Morus alba L. have a long history in Traditional Chinese Medicine and also became valued by the ethnopharmacology of many other cultures. The worldwide known antidiabetic use of the drug has been suggested to arise from a complex combination effect of various constituents. Moreover,

The reexamination of N-containing sugars from the roots of Morus alba by improved purification procedures led to the isolation of eighteen N-containing sugars, including seven that were isolated from the leaves of Morus bombycis. These N-containing sugars are 1-deoxynojirimycin (1),

A rapid, sensitive, and validated method was developed for the simultaneous determination of four iminosugars, 1-deoxynojirimycin (DNJ), d-fagomine (FAG), 2-O-a-d-galactopyranosyl-DNJ (Gal-DNJ), and 4-O-β-d-glucopyranosyl-fagomine (Glu-FAG), in mulberry leaves. The method used hydrophilic

Metabolism, transformation and dynamic changes of DNJ, 2-O-α-D-Gal-DNJ, fagomine, isofagomine and 4-O-β-d-Glc-fagomine from mulberry leaves in silkworms at different instars were observed. UPLC-Q/TOF-MS and UPLC-TQ/MS methods were adopted for qualitative and quantitative analysis respectively. Three

Mulberry leaves are rich in aza-sugars, particularly 1-deoxynojirimycin (DNJ), fagomine, and 2-O-α-d-galactopyranosyl-1-deoxynojirimycin (GAL-DNJ), which have antidiabetes and antiobesity properties. To help us understand the mechanisms of action of aza-sugars, pharmacokinetic studies are

Mulberry 1-deoxynojirimycin (DNJ, a potent alpha-glycosidase inhibitor) has been investigated thoroughly for its analytical methods and therapeutic potential against diabetes, whereas little attention has been given to other iminosugars such as 2-O-alpha-D-galactopyranosyl-DNJ (GAL-DNJ) and
