vitis labrusca/glutathione

One-year-old grapevines (Vitis labrusca L. cv. Concord) were supplied with 0, 5, 10, 15, or 20 mM nitrogen (N) in a modified Hoagland's solution twice weekly for 4 weeks. As leaf N decreased in response to N limitation, leaf chlorophyll (Chl) decreased linearly whereas leaf absorptance declined

Bioactive polyphenols in grapes are influenced by grape variety and cultivation conditions. The Vitis labrusca L. varieties are cultivated in tropical regions and used for grape juice production. We hypothesized that polyphenols from tropical grape juices would beneficially affect redox homeostasis

Sparkling wines were elaborated with the nontraditional varieties Villenave, Niagara, Manzoni, and Goethe, and monitored in relation to the changes in phenolic composition, browning index, and glutathione content during 18 months of biological aging (sur lies). Important changes in the phenolic

This study analyzed fruit stem extract (MGFE) from Muscat Bailey A grape (Vitis labrusca × Vitis vinifera) for their ameliorative effects on Ultraviolet B (UVB)-induced skin damage in Balb/c mice. Well established in vivo assays were used to determine the biological effects of MGFE upon UVB

OBJECTIVE The aim of this study was to evaluate the potential protective effects of ad libitum black grape (Vitis labrusca) juice against liver oxidative damage in whole-body acute X-irradiated rats. METHODS Animals were fed ad libitum and drank voluntarily black grape juice or placebo (isocaloric
