The aging process contributes to the sensory evolution of alcoholic beverages, producing changes in color and flavor final product. Traditionally, has occurred by storing beverages wooden barrels for several months or years. To meet demand aged there is a need large storage areas, number barrels, and, consequently, volumes stored Evaporation losses can also occur. In addition reactions beverage...

A series of novel 4-amino-5-mercapto-3-[(3-aralkyl amido/imidoalkyl) phenyl]-1,2,4-triazoles (5a-d) were obtained by treating m-(aralkyl amido/imidoalkyl) benzoic acid hydrazides (3a-d) with carbon disulphide in alcoholic KOH and hydrazine hydrate, respectively. These triazole derivatives were employed in the synthesis of 5-[(3'-aralkyl amido/imidoalkyl) phenyl]-1,2,4-triazolo[3,4-b]-1,3,4-thia...

Ninety-four samples of Asturian natural cider were analyzed for titratable and volatile acidities, pH, alcoholic, total polyphenol, and acidic polysaccharide contents, nonvolatile acids, polyalcohols, residual sugars, and major volatile compounds. A partial least-squares regression analysis (PLR-1) was performed to correlate the chemical composition and the origin of the raw material, the cider...

Six new asterosaponins, leptasteriosides A-F (3-8), one new and one previously known asterogenins (1, 2) were isolated from the alcoholic extract of the Far Eastern starfish Leptasterias ochotensis. The structures of 1-8 were elucidated by extensive NMR and ESI-MS techniques. Compounds 2-8 showed slight or moderate cytotoxic activities against cancer cell lines RPMI-7951 and T-47D. The asterosa...

We report a comparison of the steady-state absorption and fluorescence spectra of three representative uracil derivatives (uracil, thymine and 5-fluorouracil) in alcoholic solutions. The present results are compared with those from our previous experimental and computational studies of the same compounds in water and acetonitrile. The effects of solvent polarity and hydrogen bonding on the spec...

The flavonoids of Crotalaria grahamiana (family Popilionaceae) were isolated from the alcoholic extract by partition with benzene, diethyl ether, ethyl acetate respectively. On the basis of chemical and spectral analysis their structures are elucidated as 4’hydroxy flavone-7-O-rhamnoside and its aglycone.Identification of unknown compounds were established through comparison of chromatographic ...

In continuation of our search for new substituted pyridine based anti-inflammatories, reaction of 1-(2-thienyl or furanyl)-3-(2-hydroxyphenyl)-2-propen-1-ones (1) with malononitrile in alcoholic KOH solution afforded a mixture of 4-alkoxy-2-(2-thienyl or furanyl)-5H-[1]benzopyrano[3,4-c]pyridine-5-ones (2) and 2-alkoxy-4-amino-6- (2-thienyl or furanyl)-3,5-pyridinedicarbonitriles (3). Some of t...
