This study was conducted to evaluate the effect of different extraction solvents, including hydro-alcoholic (H-A), ethanolic (Et-OH), and methanolic (Me-OH), on chemical composition and synergistic antibacterial activity of Frangula alnus extract against Staphylococcus aureus and Escherichia coli. The chemical composition of the F. alnus bark extract was eval...

Blackberry (Rubus sp.) juice was fermented using four different strains of Saccharomyces cerevisiae (Vitilevure-CM4457, Enoferm-T306, ICV-K1, and Greroche Rhona-L3574) recognized because of their use in the wine industry. A medium alcoholic graduation spirit (<6°GL) with potential to be produced at an industrial scale was obtained. Alcoholic fermentations were performed at 28°C, 200 rpm, and no...

Introduction: Neuropathic pain is one of the common complications of diabetes mellitus which is caused by impairment in nerve conductivity. The role of flavonoid and polyphenol compounds in treatment of neuropathic pain has been revealed, and extract of onion contains significant amounts of these compounds. The aim of this study was to investigate the effect of alcoholic extract of onion on ...

Column chromatography of the alcoholic extract of Piper betle roots furnished aristololactam A-II and a new phenyl propene, characterized as 4-allyl resorcinol, while the petroleum-ether extract yielded a diketosteroid, viz. stigmast-4-en-3,6-dione. All these compounds were characterized by spectroscopic means. Isolation of these compounds from this source is being reported here for the first t...

In recent years, intensive studies have been carried out regarding the sensory activity of the individual components of the odours of various alcoholic beverages and the dependence between the odour and the chemical composition of the volatile fraction of these products, using gas chromatography with olfactometric detection (GC–O). GC–O is a technique based on sensory evaluation of the eluate f...

Alcoholic and aqueous extracts of endangered medicinal plants Balanites aegyptiaca and Tylophora indica were analyzed for antibacterial potential against various gram positive and gram negative bacteria including resistant strains harbouring bla genes by agar well diffusion method. Alcoholic extracts of both the plants showed activity against wider range of tested bacteria as compared to aqueou...

As an easily adapted culture, with overloaded production in some parts of the globe, apples and their by-products are being redirected to pharmaceutical, canning beverages industries, both alcoholic non-alcoholic. Fermentation is generally considered increase bioavailability bioactive compounds found apple, by impacting, through a high degree changes, product’s properties, including composition...

Abstract In this research, the chemical characterization of fixed and volatile compounds two different tannins in aqueous solution (Pratiko® L-Harvest L-Fruit) extracted from oak wood, has been studied. The influence above tannins, at concentrations, on alcoholic fermentation kinetics composition sensorial characteristics a white wine were then evaluated. wines added compared to control showed ...
