The skins and seeds of grapes are known to be rich sources of phenolic compounds, both flavonoids and non-flavonoids. The aim of the present study is to determine polyphenolic composition, antioxidant potential along with free radical scavenging activity and antimicrobial properties of ethanol extract of Grape skin and seed. Grape seed showed high antioxidant and antimicrobial activity compared...

The identification of archaeological charred grape seeds is a difficult task due to the alteration of the morphological seeds shape. In archaeobotanical studies, for the correct discrimination between Vitis vinifera subsp. sylvestris and Vitis vinifera subsp. vinifera grape seeds it is very important to understand the history and origin of the domesticated grapevine. In this work, different car...

Infusions and extracts of different grapes inactivated poliovirus; agents responsible for this property resided in the skin of the grape. Commercial grape juice at both natural and neutral pH inactivate various enteric viruses and herpes simplex virus; a 1,000-fold reduction in poliovirus infectivity occurred after incubation with grape juice, pH 7.0, for 24 h at 4 degrees C. A variety of wines...

GRAPE (GRavity PipE) processors are special purpose computers for simulation of classical particles. The performance of MD-GRAPE, one of the GRAPEs developed for molecular dynamics, was investigated. The effective speed of MD-GRAPE was equivalent to approximately 6 Gflops. The precision of MD-GRAPE was good judging from the acceptable fluctuation of the total energy. Then a software named PEACH...

Grape seeds represent a high percentage (20% to 26%) of the grape marc obtained as a byproduct from white winemaking and keep a vast proportion of grape polyphenols. In this study, seeds obtained from 11 monovarietal white grape marcs cultivated in Northwestern Spain have been analyzed in order to characterize their polyphenolic content and antioxidant activity. Seeds of native (Albariño, Caiño...

The purpose of present study was to investigate the effect of water and ethanol extracts of red grape seeds on inhibition of pancreatic -amylase and lipase in vitro. Total proanthocyanidins were determined in grape seed extracts (GSEs). Different concentrations (400, 800, 1300 and 1800 ppm) of each GSE were employed to evaluate their potentials on pancreatic -amylase and lipase after pre-incuba...
