Vine tea extract manufacturer
Our Vine tea extract comes from southern China. It is known as the "king of flavonoids" in Chinese tea culture. We extract the active ingredient dihydromyricetin (DHM) from its young stems and leaves through modern refining technology. This active ingredient has multiple effects on liver protection, lowering blood lipids and blood sugar, anti-inflammatory, antibacterial and antioxidant. As a natural ingredient, its safety has been proven and it is widely used as a raw material for skin care products, health care products and pharmaceuticals.

Products Description
1. High-content 98% Vine tea extract:
The high-content Vine tea extract we produce uses advanced purification technology to extract high-purity dihydromyricetin from the young stems and leaves of Ampelopsis grossedentata, ensuring that impurities are controlled within 0.5%. In addition, compared with traditional rattan tea extracts, this product greatly increases the concentration of DHM, making every milligram rich in powerful pharmacological activity.
2. 30% water-soluble Vine tea extract:
Although DHM has rich pharmacological effects, it is not easily soluble in water and has a low absorption rate in the human body, which limits the bioavailability of the product. To solve this problem, we developed a 30% water-soluble DHM product. By encapsulating the DHM molecular structure, using sodium caseinate and β-cyclodextrin, we have greatly improved its solubility in water, making your application range wider. Currently, this specification is used in personal care, skin care products and food and beverage fields.
3. 75% Vine tea extract: Breakthrough bioavailability improvement
The traditional bioavailability of Vine tea extract is only 4.21%, which means that most of the ingested DHM is not effectively absorbed and utilized by the human body. To address this problem, we have innovatively developed DHM with a bioavailability of up to 50%. This breakthrough technology enhances the stability and absorbability of DHM by molecularly modifying it, making it retain longer in the intestines, thereby significantly improving the absorption efficiency of DHM by the human body.
In this 75% DHM product, DHM not only achieves a qualitative leap in bioavailability, but also retains all its original functionality. Whether in health foods, functional beverages, or pharmaceutical products, it can achieve better health effects with less dosage.
The physical and chemical properties of our dihydromyricetin
kintai dihydromyricetin is a white powder with low solubility at room temperature and in cold water. It is easily soluble in hot water, hot ethanol, methanol, and slightly soluble in ethyl acetate. Because it contains an o-triphenolic hydroxyl structure, it is easily oxidized and has poor stability. Many factors such as pH value, temperature, metal ions, and solvents have an impact on its stability.
According to our company's existing research, pH value is an important factor affecting its stability. Dihydromyricetin is stable under weakly acidic conditions with a pH value of ≤4, but an increase in pH value will accelerate its oxidation rate. Under alkaline conditions with a pH value of ≥9, it will be oxidized and turn yellow. The second factor is temperature. As the temperature increases, its instability will increase, and an irreversible oxidation reaction will occur. It has different sensitivities to different metal ions. Al3+, Fe3+, Cu2+, etc. play an inducing catalytic role in its oxidation, and contact needs to be avoided during application.
Pharmacological effects of Vine tea extract:
1. Antioxidant Activity: Relevant researchers from our team have shown that our Vine Tea Extract has significant antioxidant capabilities. Among them, laboratory testing found that kintai dihydromyricetin has a scavenging rate of 73.3% to 91.5% of stable free radicals DPPH, and can inhibit linoleic acid peroxidation at a concentration of 0.01% to 0.04%. Its effect is similar to that of synthetic antioxidants. Oxidant TBHQ is comparable or even better. Its antioxidant mechanism in the linoleic acid peroxidation system triggered by FeSO4 is to complex Fe²⁺, thereby preventing the peroxidation reaction triggered by Fe²⁺.
In addition, it can effectively inhibit lipoxygenase, with a half inhibitory concentration (EC50) of 6.7 to 74.1 mmol, showing competitive inhibition of linoleic acid at the active site of lipoxygenase. It has a strong scavenging effect on free radicals O2⁻, ROO⁻ and OH⁻. Its scavenging ability for DPPH free radicals is stronger than vitamin C (Vc), and it significantly increases SOD (superoxide dismutase) activity. , reducing the MDA (malondialdehyde) content.
2. Antibacterial activity: kintai's vine tea extract dihydromyricetin has broad-spectrum antibacterial effects on a variety of Gram-positive and Gram-negative bacteria, such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Fu Shigella, Bacillus subtilis, Klebsiella pneumoniae, Proteus mirabilis and Salmonella paratyphi b all showed significant antibacterial effects, and the minimum inhibitory concentration (MIC) was low.
3. Anti-inflammatory and anti-allergic effects: Kintai researchers found that dihydromyricetin has significant anti-inflammatory and anti-allergic effects. It inhibits the dilation and increase of permeability of auricular blood vessels in a dose-dependent manner, reduces the degree of edema, and shows strong efficacy. Inhibitory effect on acute inflammation. Its anti-inflammatory and anti-allergic mechanism mainly inhibits the production of leukotrienes, a metabolite of arachidonic acid, inhibits the synthesis or release of histamine, and scavenges oxygen free radicals.
4. Inhibition of tyrosinase activity: Researchers found that this ingredient has a significant inhibitory effect on the monophenolase and diphenolase of tyrosinase, with inhibition rates of 95.87% and 69.01% respectively. DMY inhibits monophenolase by prolonging the lag time of the enzyme-catalyzed reaction (from 0.38 minutes to 0.97 minutes), and the inhibition of diphenolase shows a reversible mixed inhibition mode, indicating that dihydromyricetin is a natural tyrosinase Inhibitors.
Benefits and Application
