Grape Skin Extract
Aliases: Anthocyanins, Grape Skin Pigments
Latin Name: Vitis vinifera
Specification:
- Polyphenols 25%-85% by UV
- Resveratrol 2%-5% by HPLC
Functions:
- Antioxidant Properties: Anthocyanins, found in grape skin, possess strong antioxidant effects, effectively scavenging free radicals in the body. They reduce the activity of oxidases and inhibit the formation of oxidative stress.
- Cholesterol & Lipid Regulation: In animal studies, grape skin extract has shown the ability to lower triglyceride levels in hyperlipidemic rats and improve the levels of high-density lipoprotein cholesterol (HDL-C).
- Anti-mutagenic, Anti-tumor, and Anti-allergy Effects: Studies have indicated that grape skin extract exhibits anti-mutagenic and anti-tumor activities, along with its ability to suppress allergic reactions and protect the gastric mucosa.
- Cognitive Benefits: Research on Alzheimer's disease models suggests that grape skin extract significantly improves cognitive function and memory in rats. It enhances the activity of key enzymes in the brain, such as superoxide dismutase, nitric oxide synthase, and acetylcholinesterase. Additionally, it inhibits malondialdehyde (MDA) activity and reduces the expression of β-APP and β-AP positive neurons in the hippocampus and cortex, which are markers of Alzheimer's disease.
- Neuroprotective Effects: By reducing oxidative stress and enhancing the cholinergic system, grape skin extract may help prevent the formation of β-amyloid plaques, which are associated with age-related cognitive decline, and could potentially serve as a preventative treatment for early-onset dementia.
- Antioxidant and Free Radical Scavenging: As a potent antioxidant, anthocyanins from grape skins are excellent at neutralizing free radicals, thus helping to delay aging and reduce the risk of degenerative diseases.
