Analysis of Proanthocyanidins in Grape Seed Extracts, Health Foods and Grape Seed Oils
Grape seed extract (GSE) is one of Japan's natural food additives, and is recommended for use as an antioxidant. The component of interest is polyphenol, mainly proanthocyanidins, which are condensed tannins. A vanillin-hydrochloric acid (HCl) assay is specific for flavan-3-ol. The sensitivity of GSE components to the vanillin-HCl assay differed according to the chemical structure. We applied t...
متن کاملProtective Effect of Grape Seed Proanthocyanidins against Liver Ischemic Reperfusion Injury: Particularly in Diet-Induced Obese Mice
BACKGROUND Hepatic ischemia and reperfusion injury (IRI) is a major complication in liver surgery, and hepatic steatosis is a primary factor aggravating cellular injury during IRI. Both pro-inflammatory cytokines and reactive oxygen species (ROS) are key mediators of hepatic IRI. Ischemic preconditioning (IpreC), remote ischemia preconditioning (RIPC) and ischemic postconditioning (IpostC) have...
متن کاملEffect of heating conditions of grape seeds on the antioxidant activity of grape seed extracts
This study was carried out to evaluate the effect of heating and physical conditions of grape seeds on the antioxidant activity of their extracts. Two forms of grape seeds, whole and powdered forms, were heated at four different temperatures 50, 100, 150 and 200 C. After heating, grape seeds were extracted with 70% ethanol (0.1 g grape seed/10 mL of 70% ethanol), and total phenol contents (TPC)...

Background Exposure to glucocorticoids such as dexamethasone (Dex) leads to numerous changes in various biological systems including the reproductive system .The present study investigates the efficacy grape seeds , source of the most useful groups of plant flavonoids, phenolic procyanids, to attenuate Dex-induced spetmatogenic defects in the mouse testicles. MaterialsAndMethods A total of 32 m...
متن کاملDermal wound healing properties of redox-active grape seed proanthocyanidins.
Angiogenesis plays a central role in wound healing. Among many known growth factors, vascular endothelial growth factor (VEGF) is believed to be the most prevalent, efficacious, and long-term signal that is known to stimulate angiogenesis in wounds. The wound site is rich in oxidants, such as hydrogen peroxide, mostly contributed by neutrophils and macrophages. We proposed that oxidants in the ...
