Polygonum Cuspidatum Extract is extracted and purified from dried roots and rhizomes of Polygonum Cuspidatum (Giant Knotweed) through ethanol extraction, macroporous resin separation, crystallization and spray-drying technology.
The core functional marker component are Trans-Resveratrol & Polydatin (resveratrol glucoside).
Resveratrol is a high-activity natural polyphenol monomer, it provides powerful antioxidant and anti-aging benefits with stable quality and high purity.
It scavenges free radicals, inhibits lipid peroxidation, protects cell DNA and mitochondria, and is widely used in anti-aging health products and cosmetics.
It helps regulate blood lipid levels, inhibits platelet aggregation, reduces atherosclerosis, and supports endothelial function.
It suppresses pro-inflammatory cytokines such as TNF-α and IL-6, alleviating chronic inflammatory responses.
It enhances insulin sensitivity and assists in maintaining healthy blood glucose and lipid metabolism.
It has been studied for inducing apoptosis, inhibiting proliferation, and suppressing metastasis of tumor cells in experimental research.
