Determination of 5-Hydroxymethyl-2-furaldehyde of Crude and Processed Fructus Corni in Freely Moving Rats Using In Vivo Microdialysis Sampling and Liquid Chromatography
The purpose of this study was to develop a sensitive and fast microdialysis coupled with high-performance liquid chromatographic (HPLC) method for determination of 5-hydroxymethyl-2-furaldehyde (5-HMF) in free-moving rats after i.g. administration of the aqueous extract of crud Fructus corni and its processed products of jiuzheng pin (JZP). The concentration of 5-HMF in free-movi...
متن کاملChemicals from Biomass: Aerobic oxidation of 5-hydroxymethyl-2-furaldehyde into diformylfurane catalyzed by immobilized vanadyl-pyridine complexes
Introduction 5-Hydroxymethyl-2-furaldehyde (HMF), as diformylfurane precursor (DFF), is obtained from fructose or glucose dehydration. DFF is a versatile chemical, and there are numerous reports describing various applications as a monomer, as starting materials for the synthesis of pharmaceuticals and antifungal agents [1]. To date, few reports describe the use of air to oxidize (HMF) with het...
متن کاملCoupling of nanoporous chromium, aluminium-containing silicates with an ionic liquid for the transformation of glucose into 5-(hydroxymethyl)-2-furaldehyde.
Micro/mesoporous chromium, aluminium-containing silicates of the type TUD-1 (Al-TUD-1, Cr-TUD-1, CrAl-TUD-1) and zeolite BEA, Cr-BEA, and related composites BEA/TUD-1 and Cr-BEA/TUD-1, were prepared, characterised, and tested as solid acids coupled with the ionic liquid (IL) 1-butyl-3-methylimidazolium chloride ([bmim]Cl) as solvent, in the transformation of D-glucose into 5-(hydroxymethyl)-2-f...
متن کاملSynthesis of 5-acetoxymethyl- and 5-hydroxymethyl-2-vinyl-furan.
5-Acetoxymethyl- and 5-hydroxymethyl-2-vinylfuran were synthesized by two routes. The first route starts from 2-methylfuran and the second from furfuryl acetate. The latter route, involving successive Vilsmeier-Haack and Wittig reactions, is suitable for producing 5-acetoxymethyl-2-vinylfuran and 5-hydroxymethyl-2 vinylfuran in 68% and 60%yields, respectively.
متن کاملDetermination of 5-hydroxymethyl-2-furaldehyde of crude and processed Fructus Corni in freely moving rats using in vivo microdialysis sampling and liquid chromatography
BACKGROUND Fructus Corni is derived from the dry ripe sarcocarp of Cornus officinalis Sieb. et Zucc. 5-hydroxymethyl-2-furaldehyde (5-HMF) is an important active composition of the Fructus Corni. However, there have been no reports on the concentration of 5-HMF in freely moving rats using microdialysis coupled with HPLC. MATERIALS AND METHODS The concentration of 5-HMF in free-moving rats aft...
