Antioxidant-Rich Ampelopsis Extract powder for Liver and Skin Health CAS27200-12-0
Ampelopsis grossedentata is a plant of the grape family. Its tender leaves are processed into an extract powder, also known as vine tea extract or berry tea extract. The main active ingredients include flavonoids such as dihydromyricetin (DHM), quercetin, and myricetin. The extract is a light yellow to white powder with moderate water solubility and a natural fragrance. It is widely used in the fields of medicine, food, and cosmetics.
Active ingredients:
• Dihydromyricetin (≥30%): core antioxidant ingredient, can scavenge free radicals (ORAC value ≥34,553 μmol TE/g), inhibit tyrosinase activity, and has a significant whitening effect.
• Quercetin: anti-inflammatory, antiviral, regulates NF-κB and MAPK pathways.
• Myricetin: lowers cholesterol and improves lipid metabolism.
Test standards:
• Purity: total flavonoids ≥50% (HPLC test).
• Microorganisms: total colony count ≤1000 CFU/g, no pathogenic bacteria.
• Heavy metals: lead ≤3ppm, arsenic ≤2ppm. |
1. Anti-inflammatory and liver protection:
• Inhibit TLR4/NF-κB/MLKL pathway, reduce inflammatory factors (TNF-α, IL-6) and oxidative stress markers (MDA) in alcoholic liver disease (ALD) model mice, and improve liver pathological damage.
• By regulating the gut-liver axis, repair the intestinal barrier and reduce the entry of endotoxin into the blood circulation.
2. Metabolic regulation:
• Improve the glucose and lipid metabolism of type 2 diabetic rats, reduce fasting blood glucose (FBG) and total cholesterol (TC), and upregulate the expression of liver SIRT1, and PGC-1α proteins
3. Antioxidant and anti-aging:
• Clear ROS, inhibit UV-induced collagen degradation, and reduce skin wrinkle formation (clinical trials show that collagen density increased by 18% in 28 days).
• Reduce cell pyroptosis and inflammatory response by inhibiting NLRP3 inflammasome.
4. Antiviral and immune regulation:
• Inhibit influenza virus H5N1 and H9N2 subtypes in vitro, with a killing rate of up to 99.99%.
• Activate macrophages and NK cells to enhance innate immunity.
1. Medicine and health products:
• Auxiliary treatment of alcoholic liver disease
• Diabetes management: compounded with pueraria flavonoids into sugar-control capsules
2. Cosmetics:
• Whitening essence: contains 0.5%-3% extract, inhibits melanin production (tyrosinase inhibition rate ≥ 95%).
• Anti-aging mask: combined with yeast β-glucan to improve skin elasticity.
3. Food industry:
• Functional beverages: added to low GI meal replacement powder to reduce calorie intake.
• Natural preservatives: replace chemical preservatives and extend the shelf life of food.
