Characterization of proanthocyanidins from grape seeds

Fitoterapia, 2000
Leucoselect (grape seed selected proanthocyanidins) was analyzed. HPLC thermospray mass spectrometry (TSP-MS) allowed the detection of monomeric flavan-3-ols and dimeric proanthocyanidins. Fractionation over Sephadex LH-20 resin and analysis of the isolated fractions by gel permeation chromatography (GPC) and electrospray mass spectrometry (ESI-MS) led

Vasodilating Procyanidins Derived from Grape Seeds

Annals of the New York Academy of Sciences, 2002
Abstract: We have shown in previous work that extracts of grape seeds (GSE) and skins, grape juice, and many red wines exhibit endothelium‐dependent relaxing (EDR) activity in vitro. This EDR activity involves endothelial nitric oxide (NO) release and subsequent increase in cyclic GMP levels in the vascular smooth muscle cells.

Drying kinetics of grape seeds

Journal of Food Engineering, 2008
Abstract Drying of grape seeds representing waste products from white wine processing (Riesling), red wine processing (Cab Franc), and juice processing (Concord) was studied at 40, 50, and 60 °C and constant air velocity of 1.5 m/s. Equilibrium moisture content had a significant effect on the normalized drying curve and was determined for each grape ...

Polyphenolics in Grape Seeds—Biochemistry and Functionality

Journal of Medicinal Food, 2003
Grape seeds are waste products of the winery and grape juice industry. These seeds contain lipid, protein, carbohydrates, and 5-8% polyphenols depending on the variety. Polyphenols in grape seeds are mainly flavonoids, including gallic acid, the monomeric flavan-3-ols catechin, epicatechin, gallocatechin, epigallocatechin, and epicatechin 3-O-gallate ...

Grape Seed Proanthocyanidins Ameliorate Doxorubicin-Induced Cardiotoxicity

The American Journal of Chinese Medicine, 2010
Doxorubicin (Dox) is one of the most widely used and successful chemotherapeutic antitumor drugs. Its clinical application is highly limited due to its cumulative dose-related cardiotoxicity. Proposed mechanisms include the generation of reactive oxygen species (ROS)-mediated oxidative stress.

Improving the quality of grape seed oil by maceration with grinded fresh grape seeds

European Journal of Lipid Science and Technology, 2011
AbstractSamples of refined grape seed oil macerated with grinded fresh grape seeds were analyzed in order to study the consumers' preferences for the new oil characteristics provided by the maceration. Physical and chemical parameters have also been analyzed to study whether they remain unchanged during this process.
