From the roots of Myxopyrum smilacifolium Blume, five known compounds, verbascoside (1), arenarioside (2), myxopyroside (3), 3-formylindole (4), and 5-hydroxymethyl furfural (5) were isolated. Their chemical structures determined by ESI-MS, 1D, 2D-NMR spectrascopic data analysis as well in comparison with those reported literatures.

Some physicochemical parameters of honey have been introduced by the International Honey Commission to evaluate its quality and origin but processes such as heating and filtering can affect these parameters. In traditional Iranian medicine, deslagging process involves boiling honey in an equal volume of water and removing the slag formed during process. The aim of this study was to determine th...

Geographical and botanical origin of honeys can be characterized on the basis physico-chemical composition, sensory properties melissopalynological analysis. No comprehensive description characteristics Czech honey has been published so far. This study provides insights that are important for correct classification. The analysed 317 samples authentic from randomly selected localities. Due to di...

2,5-Furandicarboxylic acid (FDCA) is a valuable compound that can be synthesized from biomass-derived hydroxymethylfurfural (HMF), and holds great potential as promising replacement for petroleum-based terephthalic in the production of polyamides, polyesters, polyurethanes used universally. However, an economical large-scale strategy HMF lignocellulosic biomass yet to established. This study ai...

5-hydroxymethylfurfural (HMF), accessible from various feedstocks, represents an important renewable platform-chemical, precursor for valuable biofuels and bio-based chemicals. In this work, the continuous hydrogenation of aqueous solution HMF to give strategic monomers, 2,5-bis(hydroxymethyl)furan (BHMF) 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) was investigated in a flow reactor adopting...

Ethanol production from lignocellulosic biomass comprises pretreatment, hydrolysis, and fermentation. However, several inhibitors are generated during rice straw chemical including furfural, 5-hydroxymethylfurfural (HMF), phenolics. These inhibitors, i.e., furfural HMF, toxic to yeast cells, can negatively impact growth metabolism, reduce the process efficiency yield. Total phenolics also repor...

In this study, it was aimed to determine the physical, chemical and antioxidant properties of pomegranate sauces sold in market Turkey. A total 18 were studied; 17 which purchased from market, one them produced a rotary evaporator laboratory. For each sample, analysis activity, titratable acidity, brix, hydroxymethyl furfural, pH, color analysis, sugar analyzes performed. Antioxidant activity v...
