Grape metabolites can be affected by many extrinsic and intrinsic factors, such as grape variety, ripening stage, growing regions, vineyard management practices, and edaphoclimatic conditions. However, there is still much about the in vivo formation of grape metabolites that need to be investigated. The winemaking process also can create distinct wines. Nowadays, wine fermentations are driven m...

Introduction: Antioxidants protect body against the oxidative stress caused by free radicals. This study aims at comparing the antioxidant properties of hydro-alcoholic extract and extract of Nepeta crispa (from its shoot part). Methods: The study was carried out in Lorestan University of Medical Sciences in 2012. Both hydro-alcoholic extract and essence of Nepeta crispa were prepared and an...

Abstract The aim of the paper was to determine potential using grape must and unconventional yeasts in beer production process. Samples were fermented non- Saccharomyces ( Dekkera bruxellensis 3429, Wickerhamomyces anomalus MG971261, Kluyveromyces lactis MG971263), cerevisiae Safale US-05 used as a control. Grape pasteurized and, together with wort, volumetrically introduced into fermentation f...

Receipt 10 January 2003, accepted 28 April 2003. Abstract The efficient methods for extracting phenolics from grape seeds have been of great interest to many investigators, due to the special health promoting and disease preventing effects of polyphenols. In this study, extractions were performed by using aqueous ethanol. The effects of single factors such as the concentration of ethanol, the r...

background & aim: nowadays, the application of traditional medicine and herbal medicinal plants instead of chemical and synthetic drugs has captured the attention of the researchers. the purpose of this study was to investigate the antimicrobial effects of the aquatic, ethanolic and methanolic (80%) extracts of the aerial and root parts of stachys lavandulifolia vahl which were taken from t...

Grape must harbors a complex community of yeast species responsible for spontaneous alcoholic fermentation. Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, less is known about the diversity and behavior of yeast communities present on fermenting grape must from other species of Vitis. In this work, we used a culture-dependent method to study the identity and d...

In breast cancer, in situ estrogen production has been demonstrated to play a major role in promoting tumor growth. Aromatase is the enzyme responsible for the conversion of androgen substrates into estrogens. This enzyme is highly expressed in breast cancer tissue compared with normal breast tissue. A wine extract fraction was recently isolated from red wine that exhibited a potent inhibitory ...
